Original SME SME technology story

Chemical plant explosions have occurred frequently at home and abroad, which is frightening.

One to two, people have a fear of dangerous chemicals.

But life is always inseparable from chemistry, and even the fertilizer used in the cultivation of essential grain may be explosive and dangerous goods. Ammonium nitrate is a commonly used agricultural fertilizer, but it is also the "culprit" that caused the worst industrial disaster in American history.

Smoke billowing from the explosion in the worst industrial disaster in American history.

This chemical with the word "nitrate" as the head is always disturbing.

Perhaps it is because they are often known together with explosions. For example, trinitrotoluene, the main component of TNT explosives, is made by nitration of toluene.

The great power of TNT has long been recognized. A Grenade thrown on the battlefield killed and injured a large area only contains 50 grams of TNT, and 14 kilograms of TNT can destroy a football field.

As early as the mid-19th century, Swedish engineers applied for a patent to support mixed explosives with ammonium nitrate and other combustion improvers.

Ammonium nitrate has since become a widely used raw material for industrial explosives.

A quarter pound TNT Grenade

Although ammonium nitrate can be used as an explosive, pure ammonium nitrate without combustion improver is actually the most difficult nitric explosive to detonate.

It does not burn by itself at room temperature, and ammonium nitrate is extremely insensitive to impact.

The experimental study shows that the 50kg hammer falls on solid ammonium nitrate from a height of 50cm, and its explosion probability is 0;

Compared with the famous explosive nitroglycerin, a 200g hammer can be detonated 100% when it falls from a height of 20cm.

At the same time, ammonium nitrate has a high nitrogen concentration and stable performance, so people often use it as a nitrogen-containing fertilizer.

Nitrogen fertilizer is mainly helpful to improve the yield and quality of crops.

As everyone knows, ammonium nitrate fertilizer, which made people relax their vigilance, triggered a sudden compound disaster of land, sea and air.

Ammonium nitrate fertilizer

After World War II, although the United States won the war, most areas fell into the post-war economic depression.

However, the southern city of Texas is a different story.

This coastal city is busy day and night, with chemical plants and oil refineries running nonstop, and there are endless cargo ships in the port.

At that time, Texas was praised as a "port of opportunity" by major American media and newspapers, and it was the core of industrial development in the South.

This prosperity made the whole country envy, but soon, the prosperous industrial development also brewed a small Mars that destroyed everything.

By 1947, about 2,500 ships visited the ports in Texas every year, and even Monsanto opened a chemical plant in the town.

On April 16th, the wharf began to operate before dawn as usual, but it was a special day recorded in American industrial history.

There is a cargo ship, the Grand Camp, moored beside the port. This French cargo ship has been staying for five days.

The ship is loaded with some oilfield equipment, drill pipes, hemp ropes and weapons and ammunition shipped from Belgium.

And its main "passenger" is actually 2300 tons of ammonium nitrate fertilizer.

At 8 o’clock in the morning, the crew was carrying the few remaining bags of ammonium nitrate into the cabin, when a smell of smoke caught their attention.

They looked intently and saw that the smoke seemed to be coming from the No.4 cabin where fertilizer was piled up.

Perhaps some ignorant crew member or docker ignored the no-smoking sign and smoked on the ship, which caused the fire.

The fire quickly spread to the deck and hull surface, and the smoke became bigger and bigger.

The crew quickly picked up fire extinguishers and fire pipes to put out the fire, and more than 20 firefighters arrived in time.

Seeing that the fire did not decrease, it became more and more intense, and the crew came up with another fire extinguishing method.

Rescuers stopped using water to put out the fire, but sealed the warehouse with slats and covered it with tarpaulins;

Then the high-temperature steam is introduced into the cabin, and it is intended to squeeze out the oxygen in the cabin in this form.

In this way, without one of the three elements of combustion, combustion can not continue.

This method was a common fire fighting method for cargo ships at that time, and the captain also mixed selfishness in it-reducing the loss caused by the wet goods.

* Note: Material combustion requires three elements: combustion improver, combustible and temperature reaching the ignition point. Among them, oxygen is the most common combustion promoter.

People never expected that this method was really good, but it was equivalent to adding fuel to the fire for the cargo ship transporting ammonium nitrate.

More terrible than the fire of ammonium nitrate is the explosion.

Although ammonium nitrate is resistant to impact, it is very fragile in the face of high temperature.

When the temperature reaches about 165℃ or comes into contact with an open flame, solid ammonium nitrate will rapidly decompose to produce nitrous oxide and water vapor.

Nitrous oxide will also be converted into oxygen at high temperature, and the gas that rescuers tried their best to remove reappeared.

At this time, the reaction brewing in the air is not just as simple as burning.

The high temperature and high pressure environment created by firefighters made the warehouse a closed container to accelerate the explosion reaction.

People didn’t know anything about it at that time, only to find that even with powerful rescue forces, the fire was still too big to control.

At 8: 30, the captain ordered to abandon the Grand Camp and bear the loss of all the goods.

However, he was only distressed to lose a ship and cargo, but he didn’t expect the fire to turn into a bigger disaster.

At 9: 12, a loud bang from the port made almost the whole city tremble.

A fireball went straight into the sky and turned the sky red. Thick smoke soared to an altitude of 610 meters and spread everywhere. Part of the hull melted into pieces and jetted out of the dock.

Two planes accidentally flew over at this time and were directly destroyed and fell.

The explosion near the wharf caused the 160km water body in Fiona Fang to be choppy, which triggered a tsunami, and set off waves as high as 4.5m, hitting the land.

Even Houston, 40 kilometers north of Texas, felt a violent vibration, and the window glass of some houses was directly shattered.

This has become a major disaster facing the sea, land and air in all directions.

In the sudden explosion, none of the first firefighters who entered the rescue survived.

Nearby residents took refuge at home with trepidation, but they still could not escape the surging tsunami.

The fire that continues the explosion is still going on, which makes people afraid to get close.

The busy Texas dock is not a harbor of the Grand Camp, but dense cargo ships and chemical plants and refineries along the coast have become another hidden danger.

Just 15 hours after the explosion, people have not recovered from it, and the second explosion happened.

A large number of chemical plants and refineries are densely distributed.

On the coast 200 meters away from the Grand Camp, there is also a cargo ship named Success.

This cargo ship also contains nearly 1000 tons of ammonium nitrate and 180 tons of sulfur.

The explosion and fire extended to the USS Success, bringing a second thrilling explosion.

The explosion triggered a series of chain reactions, and nearby freighters and factories exploded one after another.

Successive disasters eventually killed 581 people and injured more than 3,500 people. At that time, more than a quarter of the population in Texas was killed or injured in the disaster.

Thousands of residential buildings and commercial buildings were destroyed by the tsunami, and 1,100 docks were damaged.

At that time, the prosperous capital and industrial city of Texas lost about $100 million (equivalent to more than $1 billion now).

This is the worst disaster in American industrial history, and the reasons behind it are complicated and strange.

First of all, there was a small fire in the cabin for reasons that have not been clear so far.

Then rescuers used self-defeating fire fighting methods, which eventually aggravated the explosion.

At the same time, the government regulatory agencies themselves have many loopholes.

In the era of post-war economic recovery, the industrial process has become the most important thing beyond laws and policies, and managers can only ignore the interests.

After the accident, a large-scale funeral was held for the unidentified victims.

At that time, there were about 6,000 fertilizer chemical plants in the United States, but most of them did not report the storage of ammonium nitrate in the Department of Homeland Security, although the inventory was as high as 1,300 times that of the mandatory review.

It is conceivable that the industrial intensive Texas was equivalent to hiding countless stealth bombs at that time, just waiting for an opportunity to detonate.

Once detonated, it will lead to irreparable loss of life and property.

Only in this way can the federal government face up to the audit and supervision of chemical plants and dangerous chemicals.

The government has drawn up new standards and improved the management and transportation system of dangerous chemicals. Enterprises have also established an industrial mutual aid system, and agreed to join hands in the event of danger.

This appalling Texas explosion has become history, and the United States has entered a new era of strict industrial management.

Afterwards, major media rushed to report the accident.

But no matter what era the strict system is put in, there will always be people who exploit loopholes.

Dangerous chemicals such as ammonium nitrate are never kind to those who neglect them.

In 2013, also in Texas, another chemical fertilizer factory exploded.

However, this time, it was no longer because of people’s ignorance that the mistake was made, but the chemical fertilizer plant built a non-compliant ammonia storage tank privately.

Up to 24 tons of anhydrous ammonia accidentally triggered an explosion, killing 35 people.

Sadly, some people were killed innocently in the explosion of ammonium nitrate, and some people deliberately used ammonium nitrate as a weapon for terrorist attacks.

In 2011, a nightclub in Bali exploded. This is a vicious explosion in which 202 people were killed by terrorists using ammonium nitrate.

In 1995, terrorists used ammonium nitrate to make explosives to blow up the federal building.

Chemicals usually have both advantages and disadvantages for human beings.

Ammonium nitrate is a common industrial explosive, but it is also a good fertilizer.

Nitroglycerin, which can be used as an explosive, is also a good medicine for cardiovascular diseases …

People often suffer while using them to achieve certain interests.

However, the progress of human beings lies in that no matter how dangerous the substance is, it can be controlled by human beings and finally serve human beings.

　　On February 11th, 1958, the Fifth Session of the First National People’s Congress approved and promulgated the Chinese Pinyin Scheme. In the past 55 years, the implementation of Chinese Pinyin has achieved fruitful results. Chinese Pinyin has become an important tool for reading Chinese characters, learning Mandarin, cultivating and improving reading and writing abilities, an important basis for reforming and creating minority languages, and an important basis for compiling Braille, sign language, semaphore and signal language, which is widely used in Chinese literature sorting and retrieval, and models and codes in industrial and scientific fields. With the popularization of modern information technology, hanyu pinyin is widely used to input Chinese characters, and hanyu pinyin permeates all aspects of social life, which is indispensable for a moment. As an international standard for spelling names and place names in China, as an important basis for foreign languages to refer to China and express the concept of China, and as a cultural bridge for China’s foreign exchange, Chinese Pinyin is widely used in teaching Chinese as a foreign language, foreign exchange and other fields. As a scientific, convenient and practical language tool, Hanyu Pinyin has provided great convenience for the modernization and informatization of China’s economic and social life, made important contributions to eliminating illiteracy, popularizing education, developing science and technology and improving the level of informatization in China, and played an irreplaceable positive role in socialist modernization.

　　Standing at a new historical starting point, we should, in accordance with the requirements of the 18th National Congress of the Communist Party of China on language and writing, strive to implement the Law on the Common Language and Writing and the Outline of the National Medium-and Long-Term Reform and Development Plan for Language and Writing, conscientiously sum up the achievements and experiences in implementing the Hanyu Pinyin Program in the past 55 years, properly handle the problems existing in the use of Hanyu Pinyin under the new situation, and further intensify its implementation, so that Hanyu Pinyin can play a greater role in the new era.

　　First, the implementation of the Chinese Pinyin Scheme is an important language policy in China.

　　The creation of Hanyu Pinyin Scheme has a profound historical origin and a broad mass base. Chinese characters are not phonography, and the Chinese nation’s efforts to find a scientific and appropriate pinyin scheme for Chinese have never stopped since the direct pronunciation and reverse tangent. At the end of 19th century and the beginning of 20th century, some domestic intellectuals started the phonetic alphabet movement and created more than 20 pinyin schemes. On the eve of the May 4th Movement, the government of the Republic of China promulgated the stroke-type phonetic alphabet of Chinese characters, which played a certain role in helping literacy and pronunciation. In the 1920s, Qian Xuantong, Zhao Yuanren and others created "Romanization of Mandarin", and in the 1930s, Guo Zhisheng and Qu Qiubai created "Latin New Characters of Northern Dialect", but failed to form a unified romanization scheme. At the beginning of the founding of New China, in order to meet the needs of socialist economic, political and cultural development, the CPC Central Committee made a major decision to reform the language. From 1956 to 1958, the state established the "Chinese Pinyin Scheme Review Committee" and published the "Chinese Pinyin Scheme (Draft)", and the the State Council Plenary Session adopted the "Resolution on Publishing the Chinese Pinyin Scheme (Draft)". In February 1958, the Fifth Session of the First National People’s Congress officially passed and promulgated the Chinese Pinyin Scheme. "Chinese Pinyin Scheme" is the inheritance and development of the Chinese Pinyin movement since modern times, and it is a master of more than 1,000 suggested schemes at home and abroad in the development stage. Its Latin (Roman) alphabet form and the characteristics of "phoneticization" and "internationalization" conform to the historical trend.It embodies the vision and mind of the China government and people facing modernization, the world and the future. In today’s information age, the reason why we can input Chinese characters into the computer through Chinese Pinyin and search for the required Chinese information in the massive network database is due to the scientific pragmatism of the original developers, and also to the foresight of the older generation of proletarian revolutionaries such as Mao Zedong, Zhou Enlai, Chen Yi and Wu Yuzhang who personally asked and guided the development work.

　　The formulation and implementation of "Chinese Pinyin Scheme" has always been an important content of language and writing work in China. As an important language policy in China, the formulation and implementation of the Chinese Pinyin Scheme has always been highly valued by the party and the state. In 1958, Premier Zhou Enlai defined the basic framework of the language and writing policy of the new China in his report "Tasks of Current Chinese Character Reform", and put forward three major tasks: sorting and simplifying Chinese characters, popularizing Putonghua, and formulating and implementing the Chinese Pinyin scheme. In 1986, the state held a national conference on language and writing work, which determined the guidelines and five tasks of language and writing work in the new period, and "further promoting the Chinese Pinyin Scheme and studying and solving related problems in practical use" ranked third. In 1997, the state held the second national conference on language and writing work, which determined the guiding ideology and goal of cross-century language and writing work. "Continuing to implement the Chinese Pinyin Scheme and expanding the scope of use" is still one of the four main tasks. In 2000, the 18th meeting of the 9th the National People’s Congress Standing Committee (NPCSC) deliberated and passed the Law of People’s Republic of China (PRC) on the National Common Language and Characters, which confirmed the legal status of the Chinese Pinyin Scheme as a "spelling and phonetic tool" for the national common language and characters. In 2012, the Outline of the National Medium-and Long-term Reform and Development Plan for Language and Writing set the working goal by 2020, and clearly pointed out that "Chinese Pinyin should play a better role".

　　The popularization of Hanyu Pinyin Scheme benefits from the strong support and guarantee of China’s language policies and regulations. Over the past 55 years, the state has taken various measures to promote the Chinese Pinyin Scheme. First, a series of norms and standards supporting the Hanyu Pinyin Scheme have been formulated and promulgated, such as Basic Rules for Orthography of Hanyu Pinyin, Rules for Spelling Hanyu Pinyin Letters of China Place Names, Transliteration and Transliteration of Hanyu Pinyin Letters of Minority Place Names, Spelling of Hanyu Pinyin Letters of China Names, and General Keyboard Representation Specification of Hanyu Pinyin Scheme, so as to facilitate social application. Second, through a series of policies, decrees and normative documents, clear requirements have been put forward for standardizing the use of Chinese Pinyin in the fields of press and publication, place name signs, sports activities, shop plaques and commodity packaging, and efforts have been continuously intensified. Third, we should persist in the teaching of Chinese Pinyin in the basic education stage, extensively carry out the teaching experiment of "Phonetic Literacy, Reading and Writing in Advance", and strive to improve the Chinese Pinyin ability of the people. At present, more than 1 billion people in China have mastered Chinese Pinyin.

　　The Chinese Pinyin Scheme is not only from China, but also from the world. In 1977, the Third United Nations Conference on the Standardization of Geographical Names held that "the Chinese Pinyin Scheme is perfect in linguistics, and the Roman alphabet spelling of geographical names in China is the most suitable", and adopted the resolution of "adopting Chinese Pinyin as the international standard for the Roman alphabet spelling of geographical names in China". In 1979, the United Nations Secretariat decided to adopt Chinese Pinyin as the standard for transliteration of China names and place names in various Roman alphabets. In 1982, the International Organization for Standardization adopted the Chinese Pinyin Scheme as the international standard for the spelling of Roman letters in Chinese documents. The governments of Singapore and Malaysia have adopted the Chinese Pinyin Scheme as the Pinyin Scheme for their own Chinese. China’s names, place names and other proper nouns spelled in Chinese Pinyin are absorbed in English and other Roman alphabets. Authoritative tool books published in Britain, the United States and other countries include a large number of such words. Maps published in Britain, Germany and other countries use Chinese Pinyin to spell China’s place names, and the Library of Congress and libraries in some European countries use Chinese Pinyin to spell Chinese book catalogues.

　　"Chinese Pinyin Scheme" is the crystallization of the wisdom of several generations of the Chinese nation, a representative achievement in the history of China’s cultural development, and an important achievement in the cultural construction of new China. It benefits the society and the whole people and has far-reaching influence.

　　Two, to further expand the scope of application of "Chinese Pinyin Scheme", improve the standardization level of application.

　　At present, with the rapid development of Chinese information technology, the teaching of Chinese as a foreign language is in the ascendant, and the inheritance, promotion and dissemination of Chinese culture, it is expected that Chinese Pinyin will play a greater role and help realize the "Chinese Dream" of national rejuvenation. It is necessary to further strengthen the implementation of the Chinese Pinyin Scheme according to law and improve the standardization level of its application. Specifically, we should do the following work:

　　First, strengthen the teaching of Chinese Pinyin. It is necessary to resolutely implement the provisions of the Law of the State on Common Languages and Characters that "Chinese Pinyin should be taught in primary education", to ensure that the educated can master Chinese Pinyin and apply it to all aspects of Chinese learning, information retrieval and processing, and to strengthen teacher training, supervision and inspection. We should actively explore ways and means to bring Chinese Pinyin into the national lifelong education system, so as to benefit the elderly who failed to receive Chinese Pinyin teaching in primary education. We should also vigorously promote the teaching of Chinese as a foreign language for different countries, regions and languages, and give full play to the role of Chinese Pinyin in Chinese teaching.

　　Second, strive to expand the use of Chinese Pinyin. On the basis of existing achievements, we should seriously think about how to make the Hanyu Pinyin Scheme further serve the "informatization" and "internationalization" and how to help spread Chinese culture. It is necessary to give full play to the function of Chinese Pinyin in accurately and conveniently expressing China’s unique things, concepts and ideas in foreign languages. It is expected that Chinese Pinyin will be directly used to spell China’s names, places and unique concepts such as Confucius, Tibet and Putonghua in foreign exchanges, and that more and more similar words such as Fuwa, Haibao and Chang ‘e will be used in foreign exchanges. At the same time, we should realize that the global, intercontinental and international languages that have been widely used in the world belong to all mankind, so we should take the initiative to enrich the expressions of these languages through Chinese Pinyin and create cultural wealth belonging to all mankind together with people of all countries and nationalities in the world.

　　Third, strengthen management according to law. Governments at all levels and their relevant departments should fully implement the language policy of "Hanyu Pinyin Scheme", abide by relevant national laws, regulations and standards, and actively promote and use Hanyu Pinyin. We should adhere to the "Chinese Pinyin Scheme" as a unified standard for the spelling of Roman letters in China’s names, place names and Chinese documents, take effective measures to strengthen supervision and inspection, and correct irregularities in application; It is necessary to gradually improve the standardization of the use of Chinese Pinyin in Chinese information processing, social public services and other fields.

　　Three, in-depth study, properly handle the relevant issues in the application of "Chinese Pinyin Scheme"

　　In the past 55 years, great achievements have been made in the implementation of the Chinese Pinyin Scheme, but there are still some problems in understanding and practical use, which should be paid attention to and properly handled.

　　First, we should properly handle the relationship between Chinese Pinyin and Chinese characters. The Chinese Pinyin Scheme is not a written scheme, and the Law of the State on the Common Language and Characters clearly stipulates that the Chinese Pinyin Scheme is a spelling and phonetic tool for the common language and characters in the country, and "is a unified standard for the spelling of Roman letters in Chinese names and place names and Chinese documents, and is used in areas where Chinese characters are inconvenient or unusable". Chinese Pinyin will not replace Chinese characters, and Chinese characters will not take the road of Pinyin. In the past 30 years, China’s Chinese character policy has always been to "maintain the relative stability of Chinese characters in a certain period of time and promote the standardization, standardization and informationization of Chinese characters". Language and writing departments should take the initiative to do a good job in relevant publicity work, so that the society can fully realize that the Chinese Pinyin Scheme is an auxiliary tool for the national common language, which mainly helps Chinese characters to play a role in aircraft frequency, train number, product model, phonetic sorting and retrieval of Chinese characters, and in situations where it is inconvenient or impossible to speak Chinese characters such as names and places in China in foreign languages.

　　Second, we should properly handle the relationship between Chinese Pinyin and foreign languages. Chinese Pinyin is a phonetic spelling tool for Chinese common language, not a foreign language. Correctly using Chinese Pinyin according to law and properly handling the use of Chinese Pinyin and foreign languages are related to the sovereign dignity of the country. If you need to mark the Roman alphabet, you should spell it according to the Chinese Pinyin Scheme, and you can’t use Chinese Pinyin according to the habits of foreign languages. For example, when spelling China names, you should put "surname" before "first name". On the other hand, we should also realize that with the deepening of China’s reform and opening up and the increasing frequency of international exchanges, it is not only the hospitality of our country with a history of 5,000 years of civilization, but also the inevitable requirement of China’s "opening to the outside world and integrating into the world" to provide foreign language services in the field of public services to facilitate their work, study and life. Therefore, we must make overall plans and properly handle the relationship between "safeguarding sovereignty" and "providing services", strengthen the research on related issues, clarify the different functions and usage occasions of Pinyin and foreign languages, and reverse the current chaotic phenomenon of nonstandard and inconsistent use of Pinyin and foreign languages.

　　Third, efforts should be made to study and solve relevant technical problems in practical use. According to the National Law on Common Languages and Characters, the Chinese Pinyin Scheme is not only a phonetic notation tool, but also a spelling tool. However, it should be noted that the achievements made in the implementation of the Chinese Pinyin Scheme in the past 55 years are mainly reflected in the function of "phonetic notation for Chinese characters", but the function of "spelling Putonghua" has not been fully and effectively exerted, and the research on related issues is also insufficient. The difference between spelling and phonetic notation is not only that the object of spelling is language, but that of phonetic notation is text; Moreover, spelling needs orthography, such as letter case, word segmentation, punctuation usage and other requirements of the text. In practical use, many people use phonetic notation to spell Chinese characters, which has some problems, such as no word segmentation and hyphenation, and incorrect use of case and case. Therefore, it is necessary to strengthen research and properly handle some problems in the orthography of Chinese Pinyin, such as word segmentation, idiom spelling, proper noun spelling and tone marking. In addition, efforts should be made to study and deal with a series of problems, such as how to take care of social habits in the pronunciation of the names of Chinese pinyin letters, how to coordinate the writing style of Chinese pinyin letters with related foreign letters, whether to use two spellings or three spellings in pinyin teaching, and how to express foreign or foreign proper nouns in Chinese pinyin. Only by solving these problems, further improving the efficiency of the use of Chinese Pinyin and perfecting the functions of Chinese Pinyin can it be conducive to the further implementation of the Chinese Pinyin Scheme.

　　The formulation of "Chinese Pinyin Scheme" is a pioneering work of language and writing in China. Over the past 55 years, the state has carried out a lot of fruitful work and achieved brilliant achievements in promoting Chinese Pinyin. At present, social informatization and economic globalization provide a broader and deeper application space for Chinese Pinyin. At the same time, there are still many problems in the implementation and application of Chinese Pinyin, which can not meet the needs of China’s economic construction and social development. For example, due to insufficient publicity and implementation, there are still some people in society who don’t understand the nature and function of Chinese Pinyin and can’t fully understand its scientific, practical and wide application prospects; Some localities and schools ignore and weaken the teaching and scientific research of Chinese Pinyin. In social application, the use of Chinese Pinyin is not in accordance with the relevant rules, and spelling mistakes and irregularities are common; In some fields, the phenomenon of not using Chinese Pinyin or replacing Chinese Pinyin with foreign languages has also occurred from time to time in violation of national regulations and standards. The above situation shows that in the face of the new situation of language and writing work, we must further strengthen the promotion of Chinese Pinyin, expand its application scope, constantly improve the relevant application rules, improve the popularity of Chinese Pinyin, and enhance the standardization level of Chinese Pinyin application.

　　As the competent department of the national language and writing work, the State Language Commission will take the opportunity of commemorating the 55th anniversary of the promulgation of the Chinese Pinyin Program to thoroughly implement the Law on the National Common Language and Writing, comprehensively promote the legalization, standardization, standardization and informatization of the national common language and writing, further strengthen the planning guidance, management supervision and scientific research on the implementation of Chinese Pinyin, and promote Chinese Pinyin to make due contributions to building a well-off society in an all-round way and realizing the Chinese dream.

CCTV News:July 25th this year — July 31st is the fourth "Health Promotion Week for the Elderly" in China. The theme of this year is to improve the nutrition and promote the health of the elderly. Various forms have been adopted in various localities to publicize the policies on health services for the elderly and the knowledge of popular science on health for the elderly.

In this elderly health care center in Yanjiao, Sanhe, Hebei Province, a monthly elderly health lecture hall is being held, and nutritionists explain health knowledge to the elderly.

Zhejiang has carried out the "Five Actions" of health services for the elderly in view of their visual function, oral health, nutritional status, cognitive function and wisdom to help the elderly, so as to improve their health management level. In Xilong Township, Anji County, in addition to routine physical examination items, residents over 65 years old also enjoy physical examination services such as thyroid function and tumor markers.

　　　　　　 The team of family doctors in Wenjiang District of Chengdu provides free health services for more than 1,500 disabled and semi-disabled elderly people over 65 years old in the whole district. Guo Fuze, a 77-year-old resident, had a sudden cerebral infarction seven years ago, and his lower body was paralyzed, so he couldn’t take care of himself. Family doctors came to his house regularly for health examination and rehabilitation training.

People often say that "people get old when they are old", and the most prominent aging of both legs is the aging of the knee joint. The incidence of knee arthritis in China is about 8%, and the prevalence rate of people over 75 years old is 80%.

In the orthopedic clinic of Beijing Rehabilitation Hospital affiliated to Capital Medical University, about 60% of the patients who came to see the doctor were knee arthritis.

The knee joint is the largest and most complicated joint in the human body. When we walk on the ground, go up and down the stairs and squat, it is mainly the knee joint that plays a role. The time of knee joint pain symptoms is generally earlier than other joints.

Sun Fenglong, Director of the Second Department of Orthopaedics, Beijing Rehabilitation Hospital affiliated to Capital Medical University:It has the best stability, and it also has the best flexibility, so this knee joint is very complicated in structure at first, so this complex organ is prone to many problems, the most common first sports injury, and second, from the perspective of middle-aged and elderly people, its gradual degradation process is a process of cartilage degeneration and arthritis.

　　　　　　 The symptoms of knee arthritis include joint pain, limited joint activity, joint deformity, joint swelling, muscle atrophy and so on. The prevalence rate of people over 65 years old is about 50%, and the prevalence rate of people over 75 years old is as high as 80%. There is no significant difference between male and female in mild patients. Among severe patients over 60 years old, the incidence rate of women is higher than that of men.

According to the doctor, there are some misunderstandings in the prevention and treatment of knee arthritis at present, such as low rate of seeing a doctor and low compliance, etc. So how to prevent and care the knee joint scientifically in daily life? Come and listen to the doctor.

Some patients think that knee arthritis is a minor illness, and they did not seek medical treatment in time, which led to more and more serious conditions.

The doctor reminded that at present, there is no medicine that can reverse the pathological changes of patients with knee arthritis. As long as the articular cartilage has not returned to normal, the pain will reappear and the condition will further deteriorate. Experts remind that incorrect exercise will increase the friction and load of joints and aggravate arthritis.

Sun Fenglong, Director of the Second Department of Orthopaedics, Beijing Rehabilitation Hospital affiliated to Capital Medical University:The first one is climbing the mountain, the second one is dancing, and the third one is boxing. These three kinds of sports are very prone to cartilage damage because they often require the knee joint to be in a semi-flexion state, which has great wear on the patella joint and the inner and outer sides of the whole joint.

Walking, swimming, cycling and other moderate aerobic exercises are helpful to maintain joint function, and patients with mild knee arthritis should exercise leg muscles.

　　Recently, the General Office of the State Council issued the Guide for the Construction of the Technical System of "Internet+Government Services" (hereinafter referred to as "the Guide"), which is an important measure for the state to promote the overall layout of "five in one" and the coordinated promotion of the "four comprehensive" strategic layout, make great efforts to promote the structural reform of the supply side of the government, deepen the integration of decentralization and administration, optimize service reform, further optimize public services and innovate administrative management.

　　First, a deep understanding of the great significance of "Internet+government services"

　　(A) to promote the "Internet+government services" is the consistent purpose of our party to serve the people wholeheartedly. Serving the people wholeheartedly is the foundation of our party and the source of strength for our party to always maintain its vitality. The CPC Central Committee and the State Council have always attached great importance to serving the people. Promoting "Internet+government services" means taking the people as the center, effectively solving the problems of "too many permits, difficult work, circular proof and wonderful proof", making it easier and faster for enterprises and the masses to do things, and further enhancing the public’s sense of acquisition.

　　(2) Promoting "Internet+government services" is an important way to modernize the national governance system and governance capacity. Accelerating the construction of "Internet+government service" technology and service system in an all-round way is of great significance for deepening the reform of administrative system, transforming government functions, strengthening top-level design and resource integration, promoting government data sharing and business collaboration, and building a government ruled by law, innovative government, clean government and service-oriented government.

　　(C) Promoting "Internet+government services" is a powerful starting point for deepening the "streamline administration, delegate power, strengthen regulation and improve services" reform. At present, the "streamline administration, delegate power, strengthen regulation and improve services" reform needs to be vigorously promoted with the courage of a strong man and the spirit of artisans, and with "greater openness, better management and better service", the transformation of government functions and the release of development potential will be continuously and deeply promoted. However, there are still many weak links in government services, and the innovative model of "internet plus" will become the key direction and an important starting point for the in-depth development of "streamline administration, delegate power, strengthen regulation and improve services" reform.

　　Second, it is imperative to speed up the construction of a national integrated "Internet+government services" technology and service system.

　　This time, the General Office of the State Council, together with relevant research institutions and some local departments, conducted in-depth research and formulated and issued the Guide, designed the national integrated technology and service system of "Internet+government services", put forward the information-based solution path and operation method to optimize the supply of government services, and provided important reference and guidance for various regions and departments to build online government service platforms. At the same time, it is also an active practice to implement the spirit of the important instructions of the Supreme Leader General Secretary on "building a national integrated national big data center".

　　(1) Building a unified business support system based on the standardization of the list of items.

　　It is the fundamental premise for government departments at all levels to carry out online government services and optimize the supply of government online services to sort out government services and re-engineer business processes. Based on the standardized management of the list of items, a unified business support system is constructed. The Guide requires: First, a unified catalogue list. The list of contents is compiled according to laws and regulations, including the basic elements such as the name of the item, the type of the item, the legal basis and the basic code, and does not correspond to the institution. Unified directory list to achieve the same government services at different levels and in different regions, and its basic elements are completely unified. The second is to standardize the elements of the implementation list. The implementing agency of government services will refine and improve the government services in the list of contents, and form a specific implementation list. The elements of the implementation list include 36 full elements, such as event name, basic code, setting basis, event type, implementation code and exercise content. The implementation list is the basis for compiling the government service guide, managing the government service matters and operating the management. The third is to establish a unified event management database. Relevant departments shall dynamically maintain the elements and contents of specific matters according to their respective functions and authorities, strengthen the joint management and application of government service matters, and realize the unification, synchronous update, open homology and multi-use of government service matters data.

　　(2) Building a unified basic platform system with data sharing as the core.

　　Online government service platform is an important carrier to implement "Internet+government service", which mainly realizes the functions of unified application, unified acceptance, centralized handling, unified feedback and whole process supervision of government service. The core of building an integrated online government service platform is to integrate and utilize existing resources and promote data sharing and exchange among government departments. The "Guide" proposes: First, open up the government service platform and business handling system, and connect information on matters, acceptance information, application materials, handling links and completion information to achieve one-stop service. The second is to support cross-departmental, cross-level and cross-regional information sharing, and realize that government service matters can be handled nearby, in the same city and in different places. The third is to promote the docking of the business processing system centrally deployed by the higher authorities and the lower government service platform, reduce the repeated entry of information, and improve the efficiency of government service. The fourth is to realize the sharing and utilization of basic information resources such as population, legal persons, credit information and electronic licenses, and to maximize the use value of data. The national government service platform should undertake the function of access guidance and support cross-provincial (autonomous regions and municipalities) access to national basic information resources.

　　(three) to identity authentication, electronic license, security, etc., to build a unified support technology system.

　　"Internet+government service" is the innovation of government service mode and process. Because of the characteristics of government’s own operating mechanism, it puts forward new requirements for the in-depth application of Internet technology and traditional information technology. Taking online identity authentication as an example, all regions and departments have built independent identity authentication systems in the work of online government services. For individuals, if they want to use the services provided by the government, they must register and verify, and maintaining multiple different user names and passwords has become a burden. For corporate users, it is necessary to register and use multiple certificates and media when conducting electronic bidding and other services across provinces, which also increases the cost. With the in-depth development of "Internet+Government Services", especially for some government services, it is necessary to solve the problem of real-name verification (that is, to prove that registered users are "I am me"), which in turn leads to the security risk of personal privacy data disclosure, and puts forward higher requirements for the functional complexity and security guarantee ability of the identity authentication system. On the basis of summing up the exploration experience in various places, the Guide regulates key technical links such as real-name authentication, electronic license, electronic seal and security, laying a foundation for gradually promoting a unified support and security technical system.

　　(D) to build a unified supervision and assessment system by means of electronic monitoring and third-party assessment.

　　Supervision and assessment is an important means to ensure the implementation of various tasks of "Internet+Government Services". The Guide proposes to adopt the method of "combining internal and external", organically combine internal government supervision with third-party evaluation, and promote the implementation of supervision and assessment. The first is to supervise and inspect the internal operation process of government services by means of electronic supervision. Real-time collection of government service operation data, automatic early warning and alarm for five abnormal situations, such as timeliness, process, content, discretion (charge) and integrity risk point. Open the monitoring result data and accept public supervision. The second is to organize third-party evaluation based on user experience. Around the completeness of service mode, coverage of service items, accuracy of service guide, depth of online service, effectiveness of online service, etc., scientifically set up an online government service evaluation index system to evaluate the supply capacity and service quality of online government service.

　　Third, "three integrations and five spans", give full play to the public foundation supporting role of the national e-government extranet.

　　The core of constructing "Internet+government service" technology and service system lies in information sharing. As a unified government network platform, the national e-government extranet has basically achieved full coverage at the provincial, prefecture and county levels (coverage rates are 100%, 94.6% and 90.6% respectively), and has gradually extended to township streets, horizontally connecting 133 central government departments and related units. At the same time, a unified data sharing and exchange platform for the government extranet has also been initially established. A number of cross-departmental and cross-level sharing and exchange services, such as the national online investment approval platform, the national credit sharing and exchange, and the national public resource transaction, rely on the unified data sharing and exchange platform for the government extranet to operate.

　　In the next step, we will give full play to the role and value of public infrastructure of the extranet of government affairs, strongly support technology integration, business integration and data integration, and realize cross-level, cross-regional, cross-system, cross-departmental and cross-business collaborative management and services.

　　(1) lay a solid foundation. Further strengthen the construction and application of the national e-government extranet platform, and create a new e-government infrastructure with "network access, business access to the cloud, data sharing and unified authentication".

　　(2) One network is connected. Relying on the extranet of government affairs, we will promote the construction of electronic license database and the cross-level, cross-regional and cross-departmental application of electronic licenses, unify the identity authentication system, and build a "one network" for convenience services.

　　(3) Sharing and collaboration. Based on decentralized data sharing and exchange platforms at all levels, we will integrate and establish a nationwide data sharing and exchange platform system, realize multi-level docking and intercommunication between national platforms and local platforms, and promote the smooth flow of government information resources across regions, levels and departments and the efficient cooperation of business.

　　(4) Integrated service. The government extranet will actively participate in the construction of a unified online government service platform, support the integration and construction of a comprehensive service window and an integrated government service system, and form a convenient, fast, fair, inclusive, high-quality and efficient online government service system.

In the workshop of Shandong Junfu Nonwoven Fabric Co., Ltd., workers are processing non-woven fabrics for masks. (Tonglian photo, provided by the interviewed enterprises)

　　From the usual 20 thousand yuan/ton, it has risen to more than 300 thousand yuan/ton, and the industry expects it to rise in the future … … Melt-blown non-woven fabrics (hereinafter referred to as melt-blown fabrics), known as the "heart" of masks, have increased their prices by more than 15 times in recent months, forming a very strong seller’s market.

　　During the epidemic period, masks are important protective equipment, and they have become a must-have for first-line medical care, enterprises returning to work, and people traveling, and the market demand has soared. The new production capacity of masks in China has doubled rapidly, and the supply of melt-blown cloth, the core raw material, is in short supply.

　　How scarce are the core raw materials of masks? What is the root cause of the skyrocketing price of meltblown fabrics? A large number of mask production lines have been put into production. Why don’t manufacturers take the opportunity to expand the production capacity of meltblown fabrics? When can we alleviate the shortage of raw materials for masks? With relevant questions, the reporter tracked the upstream industrial chain of masks and investigated key production links such as mask factories, cloth factories and material factories.

　　Tight cloth

　　Melt-blown fabrics are in short supply and their prices are rising rapidly, forming a very strong seller’s market.

　　"Everything is easy to say except meltblown cloth." In a mask supply sharing exchange group, a manufacturer said this.

　　The group brings together more than 100 related manufacturers in the upstream and downstream of the mask industry, and they will exchange information related to masks in the group. Although the prices of materials such as ear straps and nose bridge strips are also rising, the supply is not in short supply. Only meltblown cloth forms a very strong seller’s market.

　　"Recently, the inquiry for meltblown fabrics has quoted at least 200,000 yuan/ton, and it is not unusual for 300,000 to 400,000 yuan. Two weeks ago, we purchased 80,000 yuan/ton, and the highest was 120,000 yuan/ton. " Recently, a Shandong clothing company that switched to masks and other epidemic prevention materials "has no way to find materials". Ding Yan, the person in charge of the company, said that the rapid rise in the price of meltblown fabrics made people unprepared.

　　Melt-blown cloth is the key material to filter viruses for masks, and it can be called the "heart" of medical surgical masks and N95 masks. Medical surgical masks generally adopt multi-layer structure, which is called SMS structure for short: single-layer spunbonded layer (S) on the inside and outside, and single-layer or multi-layer meltblown layer (M) in the middle, and meltblown cloth is the best material for the meltblown layer.

　　Without meltblown cloth, we can only "let the machine wait for the cloth" Qingdao Hainuo Bioengineering Co., Ltd. owns two production lines of medical surgical masks and one production line of civil masks. They once reported to the local government that some production lines had to stop production because of the shortage of raw materials and the unavailability of goods.

　　"Meltblown fabrics that meet medical standards can’t be bought now," said the person in charge of Sheng Da Medical Hygiene Materials Co., Ltd., whose inventory of meltblown fabrics can only be used until the beginning of March. The company now has a mask production line, and two new lines will arrive at the factory in early March, when the daily demand for meltblown fabrics will increase from the current 80 to 90 kilograms to about 200 kilograms. If meltblown fabrics can’t be purchased, the new lines will be difficult to put into production. At present, the company has reported the demand information to government departments, hoping to solve the problem of medical meltblown cloth gap in the near future.

　　A flood of demand

　　On the demand side of melt-blown fabrics, the number of masks has increased greatly, and some manufacturers are looking for materials everywhere to raise the price of fabrics.

　　According to the introduction of the National Development and Reform Commission, the current capacity utilization rate of masks in China has reached 110%. As of February 29th, the daily capacity of masks in China has reached 110 million, and the daily output has reached 116 million. At present, 30 provinces, autonomous regions and municipalities except Tibet have successively set up new mask production lines, and at the same time, new mask production lines will be put into production. The person in charge of China Textile Business Association said that in the future, the market demand for meltblown fabrics will further increase.

　　In order to alleviate the shortage of masks, it has become an important way for non-mask manufacturers to become mask manufacturers. At present, many governments have opened up green channels to speed up examination and approval, and encouraged enterprises related to the industrial chain to switch to emergency production. Based on industrial and commercial registration’s changed information, from January 1st to February 7th, more than 3,000 enterprises in China added "masks, protective clothing, disinfectant, thermometers and medical devices" to their business scope.

　　In the "Docking Zone for Production Process of Key Medical Prevention and Control Materials" launched by the State Council Client applet on February 21st, the reporter saw that most enterprises are seeking the supply of meltblown cloth.

　　The reporter found that the recent surge in cloth prices was mainly reflected by small and medium-sized mask factories and new mask factories that had just changed production. The relevant person in charge of the Shandong Provincial Department of Industry and Information Technology said that the price of masks is high, and the production of masks is profitable. Coupled with the initiative of local governments, many enterprises have switched to masks, and the demand for raw materials has increased greatly, and the supply is not enough.

　　In order to ensure the supply of epidemic prevention materials in the first line of medical care, the national and local industry and information departments have formulated a number of key enterprises to ensure materials. The production of these mask factories and cloth factories is monitored by the government, and the sales are dispatched by the government, and the price increase is relatively controllable. However, people in the industry believe that there are a large number of mask factories that have emerged recently, and there are no stable suppliers. They can only look for raw materials everywhere, and they will not hesitate to buy materials.

　　A restless supply of goods

　　At the supply end of meltblown cloth, there are small factories sitting on the ground, and at the circulation end of meltblown cloth, there are middlemen who take the opportunity to earn the difference.

　　Walking into the factory of Shandong Junfu Nonwoven Fabric Co., Ltd. (hereinafter referred to as Shandong Junfu) located in Dongying City, Shandong Province, the reporter saw a busy scene. It is reported that they have been working overtime since receiving the notice from the Ministry of Industry and Information Technology on January 27, and all 10 production lines are producing at full capacity 24 hours a day. The daily output of meltblown cloth produced by Shandong Junfu is about 13 tons, accounting for 1/10 of the whole country. According to the scheduling of the state and relevant departments, it is mainly supplied to downstream enterprises in Hubei and Shandong.

　　There are not many large-scale manufacturers that can produce meltblown fabrics in China. The industry has been lacking attention for a long time, showing a tepid situation, and the industry as a whole has shown a small and scattered situation. At present, the domestic meltblown cloth production capacity is mainly distributed in a few provinces and cities such as Shandong, Guangdong, Zhejiang and Jiangsu.

　　At the supply end of meltblown cloth, the price increase of large cloth factories is not large under the control of the government, but some small factories sit on the ground and start at the price.

　　"The usual price of meltblown cloth is about 20,000 yuan/ton, and now our price is 100,000 yuan/ton. Because of our price reduction, local small cloth factories dare not raise prices, but in some provinces and regions lacking leading enterprises, small cloth factories raise prices for each other, and the prices are all above 200,000 yuan/ton. Many small mask factories want to use our materials and ask the local government to coordinate. I receive two or three hundred calls a day. " Huang Wensheng, general manager of Shandong Junfu, said.

　　A person in charge of a mask factory in Xiantao, Hubei Province said that at present, the local price of meltblown cloth in Xiantao is about 200,000 yuan/ton, while the price before the epidemic was about 22,000 yuan/ton; According to the manufacturer of meltblown cloth in Nantong, Jiangsu, in order to make the mask production line run normally, some mask factories offered high prices to buy meltblown cloth.

　　Many small cloth factories that are not included in the supply list of mask raw materials have raised prices seriously. Lin Youqiang, the person in charge of a mask manufacturer in Shandong, said that meltblown cloth enterprises with stable customers at ordinary times should not raise prices arbitrarily to maintain customer relations; A group of enterprises with no stable partners and poor management in the past maliciously raised their prices, hoping to make a quick sum of money.

　　According to industry insiders, some meltblown cloth suppliers are quite "strong" in the market, not only issuing less or no invoices for delivery, but also requiring downstream factories to use "hard currency" masks to offset the payment at a discount, and to add cash.

　　At the circulation end of meltblown cloth, there are middlemen who take the opportunity to earn the difference.

　　A small and medium-sized enterprise owner who switched to production of masks told reporters that in some WeChat groups where mask raw material resources are connected, middlemen arbitrarily charge high prices. "They opened their mouths and offered a high price of 300,000 to 300,000 yuan per ton, taking advantage of our lack of goods to rush production, and often said ‘ If necessary, transfer the money quickly. You don’t want people to get the goods ’ , create ‘ Seconds rise and kill ’ The tension. "

　　The relevant person in charge of the Industrial and Information Bureau of a city in Shandong Province said that many people hoard goods and sell them upside down, and the price is greatly increased. Many meltblown fabrics stay in the warehouse and circulation, waiting for the price increase, and supply and demand cannot match well.

　　A handsome profit

　　The reporter learned that the amazing profit of masks is an important reason why mask factories are willing to buy meltblown fabrics at high prices.

　　An insider calculated a cost account for the reporter: 1 ton of meltblown cloth can make 1 million medical surgical masks. If the meltblown fabric sells for 200,000/ton, the fabric price only accounts for 0.2 yuan in the cost of a mask. At present, the price of masks allocated by the government from Shandong is about 1.5 yuan each, and 0.2 yuan is subsidized; Each of Beijing is about 4 yuan, and each of Shanghai and Hubei is about 3 yuan. Although the cost of logistics, labor and melt-blown polypropylene has doubled recently, it also accounts for a small proportion in the price of masks.

　　On the other hand, the demand for masks has increased greatly, and some enterprises anxious to return to work do not care about the price of raw materials, which has pushed up the price of masks. "Recently, there has been a wave of enterprises returning to work all over the country. The state requires enterprises to distribute protective equipment such as masks for their employees. If each employee of each enterprise uses a mask a day, this is an astronomical figure." Lin Youqiang said.

　　According to the data of the fourth national economic census, the total employment population of domestic legal entities and self-employed households is as high as 533 million, and at least 533 million masks are needed every day based on one mask per person per day. Compared with the current daily production capacity, the mask gap is huge, and the profit margin can be imagined.

　　Awkward "thin waist"

　　The production capacity of enterprises related to the mask industry chain is "gourd-shaped", which is one of the root causes of the shortage of meltblown cloth.

　　Yu Xiaoning, chairman of Shandong Daoen Group, said that the downstream mask factory is growing rapidly at present, and the national production capacity has increased by about 2 times in the last month, which is the "bottom of the gourd"; The production capacity of meltblown fabrics in the middle reaches grows slowly, and the number of manufacturers is small due to the small structural influence of the previous market, which is "the waist of gourd"; The leading enterprises producing melt-blown polypropylene in the upstream have expanded their production rapidly, which can basically meet the downstream demand for melt-blown materials. This is the "upper end of the gourd". Take Dawn Group as an example, the company has received orders for the next two months, and the daily production capacity of melt-blown materials has expanded from about 85 tons to about 200 tons now.

　　This embarrassing "thin waist" has become a "bottleneck" that restricts downstream production expansion.

　　The reporter’s investigation found that behind the bottleneck of melt-blown cloth production capacity is the difficulty and long time of production line expansion.

　　Yu Xiaoning and other people in the industry said that compared with the mask production line, the investment is small, the technical content is not high, the reproduction is fast, and the operation is easy. The production technology of meltblown cloth is high, and the quality of meltblown cloth directly determines the quality of masks. The production line investment of the cloth factory is tens of millions of yuan, and the equipment manufacturing and installation are much more complicated than the mask production device, and the requirements for the factory building are higher, and special training is needed for the staff.

　　At present, there are not many domestic manufacturers providing complete sets of production equipment and key components of meltblown fabrics, and the production of core components such as spinneret and spinneret die is still far from foreign manufacturers, and the delivery cycle and assembly time of imported equipment are relatively long. "The import delivery cycle of dies and spinnerets takes four to six months. Domestic molds can be delivered in two months, but this kind of mold with short delivery time can’t make high-end medical products. " Huang Wensheng said.

　　The procurement cycle of parts for several months limits the delivery capacity of meltblown fabric equipment, making it difficult to put it on the market overnight like a mask machine. It is understood that some enterprises that sell complete sets of melt-blown cloth production equipment are using inventory to quickly assemble new production lines. But the design, processing and debugging of a complete production line will take about two or three months.

　　A supplier of meltblown cloth production equipment in Zhejiang said that the production line of meltblown cloth was really introduced, and perhaps the peak demand brought by the epidemic had already passed. This kind of worry has prevented many investors from entering this field. The market scale of meltblown cloth is not large. Once the epidemic situation is over, the competitive pressure of meltblown cloth manufacturers will be very great.

　　Capacity to be tapped

　　Insiders pointed out that it is urgent to strengthen the overall planning of industrial chain, tap the potential of related enterprises and leading enterprises, and maximize the production capacity of meltblown fabrics.

　　Experts believe that in order to solve the problem that the supply of raw materials such as meltblown cloth in the mask industry chain is in short supply, the following measures can be taken to ensure the supply and price stability:

　　First, promote similar technology enterprises to switch production and supply mask materials.

　　According to the statistics of China Industrial Textile Industry Association, the production technology of China nonwovens industry is mainly spunbonded. In 2018, the output of spunbonded nonwovens was 2,971,200 tons, accounting for 50% of the total nonwoven production, which was mainly used in sanitary materials and other fields; However, the proportion of meltblown process is only 0.9%, and the output of meltblown nonwovens is 53,500 tons/year. These meltblown fabrics are not only used for masks, but also for environmental protection materials, clothing materials, battery diaphragm materials, wiping materials and so on.

　　Huang Wensheng said that enterprises that produce automotive sound insulation cotton, meltblown thermal insulation cotton, meltblown oil-absorbing cotton and other materials can switch to special filter materials for mask protection, and the annual production capacity of these enterprises is about 150,000 tons. It is understood that BYD, Changan Automobile, BAIC, SAIC and other automobile manufacturers have been taking advantage of the industrial chain to mobilize the supporting manufacturers of sound-absorbing cotton to transform the original production line of meltblown cloth and transform the production of special filter materials for masks.

　　Second, take the central enterprises as the leader and speed up the production line related to meltblown cloth.

　　The relevant person in charge of the State-owned Assets Supervision and Administration Commission said that the State-owned Assets Supervision and Administration Commission attaches great importance to the changes in the supply chain and industrial chain of domestic epidemic prevention materials and guides central enterprises to take the initiative to make up for shortcomings.

　　Because polypropylene, the raw material of melt-blown cloth, is taken from petroleum, petrochemical enterprises have advantages in producing melt-blown cloth. China Petrochemical Company has invested about 200 million yuan to build 10 melt-blown cloth production lines in Yanshan Petrochemical Company in Beijing and Yizheng Chemical Fiber Company in Jiangsu Province. After all the production, the daily output can reach 12 tons of N95 mask melt-blown cloth or 18 tons of medical flat mask melt-blown cloth, which can be processed into 18 million medical flat masks.

　　Third, strengthen government regulation and control to ensure the balance of upstream and downstream supply.

　　Lei Limin, vice president of China Textile Business Association, said that at present, the production situation of mask industry chain enterprises is complicated and information communication is not smooth, so it is difficult to know the real-time situation of the return to work rate and the newly put into production line. The industry believes that the mask industry chain is characterized by "marketization of upstream raw materials and administration of downstream masks", and the contradiction between market mechanism and plan management is constantly emerging. It is recommended to take administrative measures to properly intervene and straighten out the connection.

　　Yu Xiaoning said that in the face of the epidemic, the overall decision-making from the central government to the local government has solved many problems for the development of the industry. The next step is to strengthen the overall planning of the industrial chain, form an organic combination of government, industry associations and enterprises, and use big data to make comprehensive statistics on the number, distribution, production capacity and production capacity under construction of mask factories, cloth factories and raw material factories. In the extraordinary period, entrepreneurs should organize all kinds of production work well, at the same time, they should improve their consciousness from the overall height and cooperate with the government’s dispatch, which not only completes the epidemic prevention task, but also makes the market develop more orderly.

　　According to the geological environment conditions of Sichuan Province and the weather forecast of Sichuan Meteorological Observatory, the office of Sichuan Geological Disaster Command issued the meteorological risk warning of geological disasters in Sichuan Province at 17: 00, from 20: 00 on August 22 to 20: 00 on August 23, Sichuan.Nine counties have a second-level orange warning, and 58 counties and cities have a third-level yellow warning.

　　And Covid-19 nucleic acid detection is not carry out,

　　What should we do?

　　Time is the brain, and time is life. "According to the suspected COVID-19 patient, start the emergency green channel for him!" After the medical staff of the intervention team of neurology department in the stroke center of this hospital collected nucleic acid on the spot, they immediately took three-level protective measures to implement emergency treatment for Mr. Li.

　　Guangzhou Daily Xinhua Flower City reporter learned from the hospital on April 15 that with the cooperation of emergency department, radiology department, interventional room, anesthesiology department and other departments, Mr. Li completed thrombolytic therapy in just 45 minutes and embolectomy in 90 minutes, quickly opening occluded blood vessels and finally turning the corner.

　　Start the emergency green channel

　　Complete thrombolysis and embolectomy within 90 minutes.

　　On the evening of March 31, Mr. Li suddenly felt weak in his left hand and foot, which lasted for 2 hours and still did not improve, so he came to Sun Yixian Memorial Hospital of Sun Yat-sen University for treatment. Because Mr. Li has fever symptoms and has not done nucleic acid testing, the fever clinic immediately took nucleic acid samples for him. Dr. Zhang Xiaoxu, a neurologist in the hospital, quickly identified it after receiving the treatment, judged it as an acute ischemic stroke, and immediately started the emergency green channel.

　　"The golden treatment time for ischemic stroke is usually only 3 hours to 4.5 hours. Mr. Li has been ill for 2 hours. The situation is critical and needs immediate treatment." Dr. Zhang Xiaotong said.

　　Since the results of Mr. Li’s nucleic acid have not yet come out, Dr. Zhang Xiaotong, together with the emergency department and radiology team, quickly completed the one-stop head CT plain scan, blood vessel and perfusion examination for him after taking three-level protection. The results showed that the right middle cerebral artery was occluded and the right hemisphere was hypoperfused, and the ischemic penumbra was quantified as 161.9 ml.
（Tmax>6s）。 If effective treatment is not taken in time, Mr. Li will face the possibility of permanent paralysis of his left limb.

　　The neurointerventional team in the hospital strictly followed the three-level protection required for epidemic prevention and control, quickly put on protective clothing, prepared various surgical instruments and equipment, and urgently performed bridging embolectomy.

　　Teamwork "bridging and taking bolts"

　　Hemiplegia disappeared after operation.

　　For stroke patients, "time is the brain and time is life!" In order to keep the patient’s brain function, after the examination results came out, Dr. Zhang Xiaoxu took intravenous thrombolysis for Mr. Li in the isolation ward, and then the nerve intervention team took the thrombus by relay bridging. With the cooperation of Deputy Chief Physician Yang Xinguang and Dr. Chenguang Li, the thrombus was taken by a single stent in just half an hour, which perfectly opened the occluded blood vessels and restored the effective blood flow of Mr. Li’s middle cerebral artery.

　　After the operation, Mr. Li’s left paralyzed limb can be lifted and moved freely on the operating table immediately. Two hours later, Mr. Li’s nucleic acid negative results came out and he was transferred to the neurology department for further observation and treatment. One week after the operation, Mr. Li recovered smoothly and was discharged from hospital.

　　After the operation, Mr. Li’s left paralyzed limb can be lifted immediately and move freely.

　　"In the special period of epidemic prevention and control, the treatment of stroke patients is still urgent, and it is necessary to ensure the smoothness of the emergency green channel." Professor Wang Yidong, director of the Department of Neurology and Cerebrovascular Diseases at Sun Yat-sen Memorial Hospital of Sun Yat-sen University, said that according to the hospital’s epidemic prevention and control requirements, the stroke center further improved the emergency stroke treatment process, and through multidisciplinary cooperation, a "race against time" stroke emergency treatment was successful, achieving both epidemic prevention and stroke treatment.

　　It is not enough to master "Stroke 120"

　　Be wary of these symptoms.

　　Professor Wang Yidong said that in recent years, "Stroke 120", a rapid method for Chinese people to identify stroke, has been well promoted: "1" stands for "seeing an asymmetric face"; "2" stands for "check whether there is unilateral weakness in both arms"; "0" stands for "Listen (zero) to see if the speech is clear". If the patient is suspected to have a stroke through these three steps, you can call the emergency number 120 immediately.

　　"In addition to these three common symptoms, sudden walking instability, decreased vision, and double vision may also be precursors of stroke, and everyone should also pay attention to it." Professor Wang Yidong reminded.

　　Professor Wang Yidong introduced that stroke is usually divided into two categories: ischemic and hemorrhagic, and its treatment effect has a strong time dependence. In response to ischemic stroke, the internationally recognized intravenous thrombolysis therapy is within 4.5 hours of onset. In China, some patients can also be treated with intravenous thrombolysis within 6 hours of onset. Arterial embolectomy can be performed within 24 hours of onset, but most patients are only suitable for arterial embolectomy within 6 hours of onset. Hemorrhagic stroke is usually serious, and many patients need early surgical treatment.

　　"If the treatment is carried out after the above onset time, the therapeutic effect of stroke will be significantly reduced, and the chances of disability and death will be greatly increased." Professor Wang Yidong reminded that once a stroke occurs, it is necessary to go to the nearest medical institution (usually a third-class hospital) with the corresponding stroke treatment ability as soon as possible to receive standardized treatment.
