When I stepped on the brakes, I found that the brakes were useless, the speed of the car did not decrease at all, and the brake failure was very dangerous. What is the cause of the brake failure? How should we avoid it? Many times, brake failure is actually a precursor.

First, if the brake suddenly hardens, it is likely that the vacuum booster pump fails to work, so it is necessary to check whether the vacuum booster pump is damaged or falls off.

Second, the brake suddenly becomes soft and treads like cotton. This situation may be caused by brake oil leakage due to brake oil pipe damage.

Third, when stepping on the brake, the pedal is soft and hard, and the strength is big and small. It may be that the brake oil enters water or air, and the brake oil should be removed or replaced in time. It may also be that the vacuum booster pump is aging or damaged.

Fourth, the steering wheel wobbles when you step on the brakes. This situation may be uneven grinding and excessive runout, so it is necessary to replace the brake disc in time.

Fifth, when you step on the brakes, the steering wheel deviates. This is because the brakes on one side are not working or the braking force is getting smaller. Check the brake calipers in time.

If you think it’s useful, remember to like it and pay attention to it. Braking is no small matter. If these things happen to your car, you must check it in time and don’t take any chances.

This wave of large-scale rain, snow and freezing weather before the Spring Festival opens today! This large-scale freezing rain and snow weather has a wide range of influences, a large amount of accumulated rain and snow, a long duration and a large freezing rain area, which is the strongest in winter since 2009 and is extreme. ▼

Accumulated rain and snow are heavy and snow is thick. The snowfall in Shaanxi, south-central Shanxi, southern Hebei, Henan, Shandong, Hubei, northern and eastern Chongqing, eastern Liaoning, eastern Jilin and other places can reach 10 ~ 25 mm, and the local area exceeds 30 mm; The newly added snow in northern and eastern Chongqing, northwestern Hubei, southern Henan, central and northern Shandong, eastern Liaoning and other places can reach 10-20 cm, and the local area can exceed 25 cm.

Freezing rain covers a wide range of provinces. From 1st to 4th, there were freezing rains in southern Shandong, southern Henan, central and western Hubei, northern Anhui, northern Jiangsu, northwestern Hunan, eastern Guizhou and other places. The total area affected by freezing rain was 430,000 square kilometers, with the largest impact area and the largest number of provinces since 2009.

The phase transition between rain and snow is complicated. After the process began, there was sleet or rain turning to snow in southwestern Shaanxi, southwestern Shanxi, Henan, southern Shandong, central and northern Jiangsu, central and northern Anhui, Hubei, northern Hunan and other places. On the afternoon of January 31, Shaanxi and Shanxi turned to snow; On the night of the 31 ST, snow turned in northern Henan and southern Shandong; On the afternoon of February 1, most of the above areas turned to snow.

The process lasts for a long time. The duration of the rain and snow process is 6 days, and the duration of rain and snow in Shaanxi, Shanxi, Shandong, Henan, Jiangsu, Anhui and other places is 4-5 days. The rainy weather in some areas in the middle and lower reaches of the Yangtze River can reach 6 days, and the duration of the process is also the longest since 2009.

Break the extreme value of the same period in many places. The cumulative precipitation in some areas such as southwestern Shaanxi, southwestern Shanxi, southern Hebei, Henan, Shandong, Jiangsu, Anhui, Hubei, northern Chongqing, northwestern Jiangxi, and northern Hunan will approach or exceed the historical extreme value in the same period.

The Central Meteorological Observatory issued a blue warning of blizzard at 06: 00 on January 31st: It is estimated that there will be heavy snow in parts of central and northern Shaanxi, central and southern Shanxi, southwestern Hebei, central and northern Henan, southern Shandong and northern Jiangsu from 08: 00 on January 31st to 08: 00 on February 1st, among which there will be heavy snow (10-11 mm) in parts of central Shaanxi, southwestern Shanxi and western Henan. The depth of newly added snow in some areas above is 2 ~ 4 cm, and the local area can reach more than 5 cm. In addition, there are moderate to heavy rains in parts of Shanghai, southern Jiangsu, northern Zhejiang, southern Anhui, northwestern Jiangxi, central and eastern Hubei, western and northern Hunan, and northeastern Guizhou, and heavy rains (50-60 mm) in parts of southern Anhui, northeastern Hunan, and northwestern Jiangxi. ▼

　　In the past 18 months, few people have noticed that Stan Larkin is a man without a heart.

　　This 25-year-old black guy has a thick body, likes to hang out with his younger brother and always takes his three young children to the park to play. He looks like a normal man.

　　The only special thing is that he always carries a gray backpack and never leaves his body for 24 hours. Go out, carry your bag on your back, even if you sit down for a haircut, put it at your feet.

　　Two pipes came out from the corner of the backpack, penetrated into Larkin’s clothes, buried under his ribs and connected to his "heart". As early as 2014, Larkin’s heart was removed and replaced by a Total Artificial Heart made by Syncardia Systems, Inc The backpack is filled with a portable driving device that provides power for it.

　　To put it simply, this backpack and all-artificial heart system maintain Larkin’s life.

　　It was not until May 9th that he transplanted a donor’s heart at the frankl Cardiovascular Center of the University of Michigan that he finally unloaded the backpack.

　　Cynthia’s total artificial heart handed out the baton, successfully ending its 555-day term.　　

　　"Many people may be afraid of using artificial hearts, and what I want to tell you is that you need to overcome this fear because it will help you." Before leaving the hospital, Larkin described this journey as a "roller coaster" when sharing his experiences with the public at a media meeting. He feels that he can recover quickly after surgery, thanks to the escort of the total artificial heart while waiting for the transplant.

　　"I feel like I can jog now." The man who just changed his heart two weeks ago said with a smile.

　　A machine will become my heart, think about it, a machine.

　　Larkin never thought that a man could live without a heart, let alone this happened to himself.

　　He hesitated for half a month before agreeing to the doctor’s treatment plan to install a total artificial heart for him. "A machine is going to be my heart," he said with an incredible expression. "Think about it, a machine!"

　　But he had to accept the machine. At the age of 16, Larkin went into shock on the basketball court without warning. Soon, he was diagnosed with arrhythmogenic right ventricular cardiomyopathy.

　　In human body, the heart promotes blood circulation throughout the body through the relaxation and contraction of atrium and ventricle. Larkin’s disease will make the myocardium of the right ventricle be replaced by progressive fibrous adipose tissue, which will cause the right ventricle to expand and not contract normally, which will lead to arrhythmia and even sudden death.

　　"The best choice for him is to receive a heart transplant." Jonathan Gaft, Larkin’s attending doctor and frankl Cardiovascular Center of the University of Michigan, said, "But at the same time, we feel that his condition is changing very fast, and he may not wait for the day when his matching donor heart arrives."

　　According to Billy Coen, director of the Technology and Innovation Center of Texas Heart Association, some patients with advanced heart failure often have to wait for months or even years to get a suitable heart source. Because the heart is too weak, key organs including kidneys and liver are likely to fail in the process. Without some forms of support such as artificial heart, many patients will die while waiting. According to the data provided by the American Organ Acquisition and Transplantation Network (OPTN), 49% of people on the waiting list for heart transplantation have to wait for one year or more.

　　Larkin’s situation is getting worse. After developing from right ventricular dysplasia to total heart failure with bilateral ventricular involvement, his left and right ventricles could not effectively collect and pump blood. He was so weak that he could hardly get into the car by himself.

　　Prior to this, the doctor implanted an automatic cardioverter defibrillator for him. When necessary, it will send electrical pulses to "activate" the regular operation of the heart. However, after the illness worsened, this commonly used cardiac auxiliary equipment was not enough to maintain Larkin’s life.

　　In November 2014, after a series of physiological tests, the doctor decided to remove Larkin’s heart and implant a Cynthia artificial heart to replace the original left and right ventricles and four valves.

　　This new "heart" is a pneumatic bicentric pump. After connecting with Larkin’s atrium, aorta and pulmonary artery, it began to perform its duties. As a mechanical heart, it can pump 9.5 liters of oxygenated blood per minute, which is beyond the ability of ordinary healthy heart and close to the level of athletes.

　　There is no sensor or engine in Larkin’s body. Through two pipes, the electric external driver transmits oxygen and creates vacuum, controls the synthetic material membrane separating air and blood in the ventricle of the total artificial heart, and pumps blood to the whole body.

　　"Tick-tock … … Tick-tock … …” This machine has accompanied his life all day. With each accurately calibrated compressed oxygen pulse, the driving equipment in the backpack makes a strong, stable and rhythmic sound, which sounds like a fast horse galloping through the hard road.

　　A few weeks later, Larkin, who was used to the noise, finally fell asleep with it. "It kept me alive," he said. "That’s it ‘ The sound of heartbeat ’ 。”

　　Larkin is challenging the limits of this equipment.

　　Two days before Christmas in 2014, Larkin walked out of the hospital with his family and became the first person in Michigan to leave the hospital with a total artificial heart.

　　"Although there is a backpack connected to my body, it’s like a real heart," Larkin joked. "It feels like I’m going to school with a backpack full of books on my back."

　　Like every ordinary person celebrating Christmas, he went shopping in the shopping center, went to church to participate in activities, and accomplished something he had been longing for for for a long time — — Picked up the basketball with the device that kept him alive.

　　Gaft, the attending physician, took a deep breath when he saw the pictures of him dribbling.

　　"This artificial heart is not designed for playing street basketball," Gaft said. "Larkin is really challenging the limits of this equipment."　

　　Hu Shengshou, academician of China Academy of Engineering and president of Fuwai Hospital, introduced in an article that artificial heart broadly includes ventricular assist devices and total artificial heart, in which ventricular assist devices are mainly left ventricular assist devices.　

　　It has been 80 years since the Soviet scientist De Mihov transplanted the artificial heart into dogs in 1937. In 1969, American doctor Cooley completed the first successful total artificial heart transplant in Texas Institute of Medicine, and assisted the patient with a total artificial heart for 64 hours before the heart transplant.

　　In China, the related blood pumps being developed by Tianjin TEDA Cardiovascular Hospital, Beijing anzhen hospital and Suzhou University are still in the animal experimental stage. There is no breakthrough report on the development of total artificial heart in China.

　　Cynthia total artificial heart is recognized as the most successful of more than 10 kinds of total artificial heart devices that have been published so far. Ten years ago, it was approved by the US Food and Drug Administration (FDA) as an auxiliary treatment before heart transplantation. It is also the only total artificial heart certified by the United States, Canada and Europe for clinical application.

　　Although Larkin, who came home with Cynthia’s artificial heart, can’t move completely freely, for example, the electric drive device connected to him prevents him from standing under the shower, picking up children or carrying them around his neck as usual, all this is very rare.

　　When the total artificial heart was just implanted, two pipes drilled from Larkin’s left rib were connected to a driving device called "Blue Giant".

　　It weighs 188 kilograms and looks like a washing machine. This means that Larkin can only be tethered to the hospital by this cumbersome machine until it takes the doctor months or even years to find a matching heart donor for him.

　　Fortunately, in June of that year, this small and portable all-artificial heart drive device newly developed by Syncadia Systems was approved by the US Food and Drug Administration. Larkin’s "washing machine" was replaced by a "backpack", so he no longer had to be trapped in the hospital.　

　　"When eligible patients become stable, they can switch to portable drives," the production company said. "It provides patients with a wider range of activities and allows them to return to their families and communities to wait for a matching donor heart." It is powered by two lithium-ion batteries and can be recharged with a standard power socket or an adapter of a car.

　　This equipment, weighing about 6 kilograms, was named "Freedom".

　　In order to permanently replace the human heart, it has to overcome many technical difficulties.

　　It seems that Larkin is doing well with a total artificial heart. At home, he doesn’t need more treatment, as long as he eats a low-sodium diet and takes blood-thinning drugs to keep healthy. Of course, as a person with a total artificial heart, he has to be like a robot and can’t leave the power supply for too long — — The lithium battery in the equipment is enough to run for 3 hours.

　　However, total artificial heart is only used as an alternative transitional treatment before heart transplantation, and it can not be maintained for a long time. Cynthia’s total artificial heart, which is at the forefront of the industry, is also starting the clinical trial of permanent artificial heart transplantation.

　　Academician Hu Shengshou introduced that although heart transplantation is the best treatment for many patients with end-stage heart failure who can’t be treated by drugs or surgery, it is still the goal pursued by the medical community for many years to use artificial heart instead of natural heart because of the limitation of heart source and the fact that heart transplantation is not suitable for patients under 40 years old.

　　Although the current research is more and more advanced, in order to permanently replace the human heart, the total artificial heart has to overcome many technical difficulties. For example, as an artificial mechanical device, it does not have the self-repairing function of human heart, and it is impossible to stably simulate the heart beating more than 100,000 times a day for a long time without wear.

　　"Larkin is still waiting for a heart transplant, and we hope to transplant him as soon as there is a suitable donor. During this period, he can return to health in some normal life at home, and when the opportunity comes, he will be transplanted in the best condition. " Dr Jonathan Gaft said.

　　In order to serve the heart of this substitute, Larkin’s family took over most of the work of the nurse. The mother, who was afraid of touching two pipes at first, was used to often changing the bandage covering the entrance of the pipe for her son.

　　"We have to be careful so that he won’t get infected," she said. "Now, I’m a professional."

　　After 555 days of being accompanied by Cynthia’s total artificial heart and "freedom" drive equipment, Larkin finally got a heart from a donor.

　　Now, in his chest, a fresh human heart is beating steadily.

　　This is the third heart he experienced, which made him feel "reborn". "You can stop worrying about small things and do many things that you once thought you could never do again."

　　Including hugging his three children again.

　　"They will attack me," the father showed a spoiled smile. "They can’t wait for a long time. They will hang in front of my neck, jump on my back and ride on my neck. In short, they will run around me. " China Youth Daily Zhongqing Online Reporter Chen Yinan

"Tired, have a rest."

In Chengdu Qingbaijiang Micro-products Liandahai Industrial Park, truck driver Ye Qinghua took advantage of the cargo gap and walked into the 24-hour "rest station". The temperature in the station is suitable, and the facilities and equipment are readily available. Ye Qinghua opened the refrigerator, took out a bottle of frozen mineral water and gulped it down. "It’s very convenient here. The canteen next door also provides meals of 2 meats, 2 vegetarian dishes and 1 soup. You can eat them for free by scanning the code."

Qingbaijiang is the seat of Chengdu International Railway Port, and the trains between China and Europe (Chengdu and Chongqing) are galloping, attracting many modern logistics enterprises to settle down and simultaneously expanding the group of truck drivers. As one of the busiest logistics industrial parks in Chengdu, Dahai ranks first in the city in terms of storage capacity, distribution capacity and truck flow. Every day, thousands of trucks loaded with goods come in and out from here, transporting tens of thousands of tons of goods between Chengdu and other cities.

In view of the characteristics of large mobility and scattered aggregation of truck drivers. In 2022, Dahai Industrial Park opened the "Rongouyi Warm Heart House", which provided one-stop services such as parking and maintenance to meet the needs of truck drivers who want to "drink hot water, eat hot meals, take a hot bath and sleep well". Last year, combined with the business model of truck drivers in the park, Dahai Industrial Park launched several "rest stops", with air conditioners, televisions, water dispensers, recliners, books and newspapers, which further upgraded the service model of "Warm Heart Home". According to Li Lianglun, director of Chengdu Dahai Comprehensive Management Department, after the launch of the "rest station", truck drivers use the station service more than a thousand times a month.

Since 2021, Sichuan has explored a new path of high-quality development of the industry with "wheel party building", and innovated to create an upgraded version of the driver’s home-the "warm-hearted home" for truck drivers. At present, 26 related points have been built. According to the person in charge of the Sichuan Provincial Department of Transportation, the "Warm Home" is laid out along highways, ordinary national and provincial roads, logistics parks and inland ports in the province. According to the plan, 37 "Warm Home" points will be built in Sichuan before 2025, realizing full coverage of the main freight logistics channels in the province. On the basis of broadening the points, more considerate services are also being launched.

Jintang Service Area of Chengde South Expressway has established the first "warm-hearted home" for truck drivers in the province. In the "warm-hearted home", the laundry and drying area, shower area and kitchen area are well-equipped, providing drivers and passengers with services such as bringing their own bedding to stay at the minimum of one yuan, and the "one meat and two vegetables" box lunch sold in the service area is at the minimum of ten yuan, striving for convenience and practicality.

"This is the warm home of our truck driver."

"The space is clean, the service is good, the bath is very comfortable, and the mood of the sports car is good."

……

On the register of "Warm Heart House", the truck driver expressed his affirmation of this service through a series of real messages.

On this basis, in 2023, the Jintang service area of Chengde South Expressway launched the Warm Heart Health Service Station, which opened up a safe, healthy and green rescue channel to provide health promotion, emergency rescue and safety guarantee to the drivers and passengers in the past service areas.

Warm Heart Health Service Station is equipped with automatic external defibrillator (AED), sphygmomanometer and standing medicine box. Jintang Service Area, in conjunction with county transportation department and health department, has opened a medical green rescue channel nearby and provided a special telephone for green rescue. In case of emergency, the service area staff can contact the local hospital ambulance personnel and quickly link to medical resources, so that the drivers and passengers who are in urgent need of treatment can get the most timely and fastest medical treatment.

In January of this year, Ms. Wang, a driver and passenger, was sent to the post station by her friends because she was flustered, short of breath and weak. In the post station, the staff gave Ms. Wang a simple care and contacted the hospital through the emergency phone. It took only 14 minutes. The ambulance arrived at the post station and transferred Ms. Wang to the hospital for treatment.

"The service station is committed to rapid discovery, timely treatment and effective treatment of patients, and provides a safe and healthy travel service experience for drivers and passengers in all directions." According to Yue Dongxue, director of Jintang Service Area of Chengde South Expressway, in the early stage, they conducted emergency rescue skills training to improve the self-help and mutual rescue ability of the service area in response to emergencies and accidental injuries. It is convenient for rapid discovery, timely treatment and effective treatment of patients. "Provide a safe and healthy travel service experience for drivers and passengers in all directions." She said.

　　CCTV News:On July 25 th, the "International Sharp Review" of the Central Radio and Television General Station broadcasted the title "Who is the White House in a hurry to send checks to farmers?" The article was reprinted and published by many overseas media.

　　On July 25th and 26th, Germany’s "German-Chinese Report" website, Spain’s Global Iberian Media Client, Italy’s RADIOWE website (facebook, twitter), Portugal’s Lisbon Rainbow Radio website (facebook), Brazil’s Sao Paulo World Radio and Television website (facebook), Brazil’s Rio Headline Radio and Television website (facebook), Brazil’s Romantic Radio website, Brazil’s Business Observer website, Many overseas media, such as Ururau newspaper website, Indian Daily Morning News website, Turkish Economic Observation Network, Chinese PT portal, Chinese headline APP, Portuguese New Newspaper APP(facebook, twitter), European Union Chinese website, West Africa online website, Africa Times website, Greek China website, Japanese Chinese business website and so on, have forwarded them one after another. On 26th, Hong Kong Ta Kung Pao and Wen Wei Po published this article. The main reports are as follows:

　　US President Trump said on Tuesday that he would provide an agricultural subsidy of up to $12 billion to help American farmers tide over the growing trade war between the United States and China, the European Union and other countries.

　　Prior to this, one of the reasons why the United States provoked trade wars with many trading partners was that their products exported to the United States had so-called government subsidies. Now, the White House has also begun to issue subsidies. Isn’t this hitting yourself in the face? ! Trump’s move once again proves that economists have always warned the White House, that is, "there is only a double loss in the trade war, and there is no winner."　

　　The essence of trade is win-win, whether it is cooperation or competition. However, this US administration seems to be paranoid and firmly believes that trade is a zero-sum game. Obviously, I bought bread to fill my stomach, and I have to accuse the bread seller of being a winner and a loser. This logic is too twisted!

　　The White House’s use of taxpayers’ huge funds as agricultural subsidies is the inevitable result of its imposition of punitive tariffs on goods from global trading partners, which eventually leads to retaliation from many parties. Among them, the American agricultural economic belt is one of the key targets of retaliatory measures by various countries. Those American farmers are precisely the victims of Trump’s trade war, and they are swallowing the consequences of the irrational and outrageous tariff policy of the White House.

　　As the world’s largest exporter of agricultural products, the export of agricultural products in the United States reached a record high in 2017, with a trade surplus of $21.3 billion. Since the trade war, trading partners including EU, Canadian, Mexican and China have been forced to impose retaliatory tariffs on agricultural products originating from the United States. The USDA estimates that these countermeasures will cause about $11 billion in losses to American agricultural products.

　　The United States has always accused other countries of subsidy policies, saying that this practice violates the provisions of the WTO. Now, the White House has picked up taxpayers’ money and done what it has always been illegal in its own eyes. In a sense, this is also a set of votes for the mid-term elections in November this year. This sanctimonious double standard is overbearing: "Only I can set fire, but you can’t light a lamp".

　　However, can the White House check really solve its problem? As Blake Horst, director of the Missouri Department of Agriculture, said, unless the White House policy changes, the pressure on American agriculture will continue. Short-term or temporary remedial measures cannot solve the substantive problems. Brian Kuhl, executive director of Farmers for Free Trade, believes that American farmers need contracts instead of subsidies, and with contracts, they can make plans for the future with peace of mind.

　　Previously, Trump believed that the trade war would be beneficial to the US, and the trade war would be easy to fight and win. Today’s results show that things are not as simple as he thought. This is because the US government’s subsidies to agriculture will inevitably bring out a series of related problems. Alaska Senator Lisa Mokowski is asking: What about manufacturing? Energy field? What about oil and gas industry? What is the standard of subsidy or not?

　　The New York Times pointed out in the editorial that those manufacturers who need to pay high prices for steel and aluminum because of the trade war need subsidies? Do workers who are unemployed because Harley-Davidson motorcycles transfer production lines need subsidies? Do producers of bourbon affected by the trade war need subsidies?

　　If the United States continues to subsidize other industries affected by the trade war, then the Trump administration will face many challenges, on the one hand, the problem of money bags, on the other hand, the legitimacy of subsidies. As for the legality of the latest US$ 12 billion subsidy, it is estimated that many countries will submit it to the WTO for adjudication.

　　In fact, the White House is very clear about how to solve the situation. Republican Senator Ben Sass said that a trade war is like cutting farmers’ legs, and then the White House plan is to give them a pair of pure gold crutches worth $12 billion. "The government’s tariffs and relief will not make the United States great again, but will come again in 1929 (the Great Depression)."

　　Senator rand paul tweeted: "Tariffs are equivalent to increasing taxes on American consumers and producers. If tariffs punish farmers, then the answer is not welfare, but the abolition of tariffs. "

　　Analysts pointed out that the United States continued the tariff war by granting subsidies to farmers. On the one hand, it reflected its double standards and "two-faced" approach in international trade, which showed the hypocrisy and hegemony of the United States. On the other hand, it also reflected the Don Quixote-style approach of the United States, which not only created a lot of uncertainty for other countries, but also endangered the global multilateral trading system and brought serious chaos to its own country.

Departments in charge of industry and information technology of all provinces, autonomous regions, municipalities directly under the Central Government, cities under separate state planning and Xinjiang Production and Construction Corps:

In order to implement the 14th Five-Year Plan for Industrial Green Development and the peak carbon dioxide emissions Implementation Plan for Industrial Fields, continuously improve the green manufacturing system, promote industrial green development, and help peak carbon dioxide emissions to be carbon neutral in industrial fields, we are now organizing to recommend the list of green manufacturing in 2022. The relevant matters are notified as follows:

First, the 2022 green manufacturing list recommended work requirements

Please follow the clear recommendation procedures in the Notice of the General Office of the Ministry of Industry and Information Technology on Developing Green Manufacturing System (No.586 [2016] of the Ministry of Industry and Information Technology, hereinafter referred to as the Notice), and organize local enterprises (including central enterprises, the same below) and parks to carry out declaration work and select and determine green factories and green design products in the region. Encourage all localities to establish and improve the local green manufacturing benchmarking mechanism, publish the provincial green manufacturing list, and give priority to the enterprises or parks included in the list.

In the past three years, it is not allowed to declare the list of green manufacturing in any of the following circumstances: it has not been operating normally; Accidents such as security (including network security and data security), quality and environmental pollution, and illegal acts such as tax evasion occur (subject to "Credit China" and "National Enterprise Credit Information Publicity System"); Being dynamically adjusted out of the green manufacturing list; Being found to have serious problems in the relevant inspection work of the State Council and relevant departments; Being included in the list of industrial energy conservation supervision and rectification and failing to complete the rectification as required; The person who is untrustworthy is executed, etc.

(1) Green factories

Please refer to the General Rules for Green Factory Evaluation (GB/T36132-2018) to carry out self-evaluation and third-party evaluation. If the industry standard for green factory evaluation has been published (which can be viewed on the website of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology), self-evaluation and third-party evaluation shall be conducted according to the requirements of the industry standard. The number of applications in each region will be determined according to factors such as the number of industrial enterprises above designated size.

In order to give play to the leading role of green factories in energy saving and carbon reduction, the energy efficiency level of key energy-consuming industries should, in principle, reach or exceed the Benchmark Level and Benchmark Level of Energy Efficiency in Key Areas of High Energy-consuming Industries (2021 Edition) (No.1609 of Development and Reform Industry [2021]) and Benchmark Level and Benchmark Level in Key Areas of Clean and Efficient Utilization of Coal (2022 Edition) (No.559 of Development and Reform Operation [2022]). Industries that do not specify the benchmark value of energy efficiency should, in principle, meet or exceed the advanced value of the corresponding national energy consumption quota standards. In addition, the recommended green factories in each region should be benchmarked against the existing green manufacturing level indicators, and the main indicators such as energy efficiency level should be better than the existing green factories in the same region.

(B) Green design products

Please visit the website of Energy Conservation and Comprehensive Utilization Department of the Ministry of Industry and Information Technology for the recommended range and standards of green design products this year, and check them in the "List of Green Design Product Standards". The products to be applied are only those with standards specified in the list. According to the specific requirements of the standard, prepare the self-evaluation report of green design products.

(3) Green industrial parks

All regions should organize industrial parks with good industrial foundation, perfect infrastructure and high level of green manufacturing to declare, and carry out self-evaluation and third-party evaluation with reference to the relevant requirements of green park evaluation in the Notice. The recommended green industrial parks are provincial-level and above industrial parks with product manufacturing and energy supply as the main functions, industrial added value accounting for more than 50%, legal boundaries and scope, and unified management institutions.

All-media reporter Ruan Lu Intern Lu Qun Correspondent Wang Yijun

At present, the weather is getting colder and the temperature difference between day and night is large, which is in the high incidence season of influenza.

Huang Li, deputy director of the Institute of Infectious Disease Prevention and Control of the State Center for Disease Control and Prevention, and Li Fuqiang, an expert on planned immunization, warmly reminded that to prevent seasonal high-incidence respiratory infectious diseases such as influenza, we should make preparations in advance, raise awareness of disease prevention and strengthen health protection.

What is the flu?

Influenza (hereinafter referred to as "influenza") is an acute respiratory infectious disease caused by influenza virus, which is harmful to human health. It can be divided into four types: A, B, C and D. Seasonal influenza viruses include subtype A H3N2, subtype A H1N1 (pdm09), strain B Victoria and strain B Yamagata.

According to Huang Li, the flu mainly manifests as fever, headache, general malaise and other symptoms, and the body temperature can reach 39~40 degrees Celsius. Children’s fever is usually higher than that of adults, and the symptoms may include chills, chills, aching muscles and joints all over the body, fatigue, accompanied by loss of appetite, etc., as well as sore throat, cough, nasal congestion, runny nose, retrosternal discomfort, facial flushing, conjunctival congestion and so on.

Influenza is mainly spread by droplets such as sneezing and coughing. Influenza virus survives in the air for about half an hour. It can be infected by direct or indirect contact with oral cavity, nasal cavity, eyes and other mucous membranes, and it can also be infected by touching articles infected by the virus. In crowded, closed and poorly ventilated places, influenza may also spread in the form of aerosol.

People are generally susceptible to influenza virus, and most of them are self-limited. Some patients will have complications, which can develop to severe illness or even death. The elderly over 65 years old, children under 5 years old, especially children under 2 years old, pregnant women and patients with basic diseases are high-risk groups of influenza and need special attention.

Huang Li reminded that maintaining good personal hygiene habits is an important means to prevent respiratory infectious diseases such as influenza. For example, wash your hands frequently, keep indoor ventilation, try to avoid going to crowded places, have a balanced diet, exercise, and minimize rubbing your eyes, nose and mouth when you are in public places. You should also pay attention to regular work and rest, balanced nutrition, avoid overwork, and maintain your immunity. It is best to wear a mask when you go to a medical institution for medical treatment.

"In addition, the most effective means to prevent influenza is to inject influenza vaccine, especially for key populations. Annual influenza vaccination can significantly reduce the risk of influenza and serious complications." Huang Li said.

It is recommended to vaccinate against influenza in time.

According to Li Fuqiang, according to the Technical Guide for Vaccination of Influenza Vaccine in China (2023-2024) recently issued by the China Center for Disease Control and Prevention, annual vaccination with influenza vaccine is an effective means to prevent influenza, which can effectively reduce the risk of influenza and serious complications among the vaccinators. Suggest ≥ People who are 6 months old and have no vaccination contraindications should be vaccinated against influenza, especially the following key groups are recommended to give priority to vaccination:

1 medical personnel, including clinical rescue personnel, public health personnel, health and quarantine personnel, etc.;

2. Participants and security personnel in large-scale activities;

3. Vulnerable people and employees in old-age care institutions, long-term care institutions, welfare homes and other crowd gathering places;

4. People in key places, such as kindergartens, teachers and students in primary and secondary schools, and detainees and staff in prison institutions;

Family members and caregivers of infants under 5.6 months old and pregnant women;

6. Other people at high risk of influenza, including elderly people aged 60 and above, children aged 6 months to 5 years, and patients with chronic diseases.

Usually, antibodies with protective level can be produced after 2~4 weeks of influenza vaccination, and it is best to complete the vaccination before the peak of influenza epidemic in autumn and winter. In the same influenza epidemic season, people who have completed the whole vaccination according to the vaccination procedures do not need to be vaccinated again.

Li Fuqiang introduced that influenza vaccine is a non-immunization program vaccine, and residents can be informed, voluntary and self-funded. At present, influenza vaccines used in China are mainly divided into two categories: inactivated influenza virus vaccine and live attenuated influenza virus vaccine. The influenza vaccines approved for marketing in China include trivalent inactivated vaccine (IIV3), trivalent inactivated vaccine (LAIV3) and tetravalent inactivated vaccine (IIV4), all of which can effectively prevent influenza virus infection. Residents can choose one influenza vaccine by themselves. At present, there are sufficient reserves of influenza vaccine in vaccination clinics all over the state.

Because influenza virus is easy to mutate, it is necessary to get flu vaccine every year. Like many other vaccines, influenza vaccination does not necessarily mean that you will not get the flu, but it can alleviate the symptoms after getting the flu, significantly reduce the risk of developing into a serious illness, and avoid developing into a serious illness and death.

Experts from the State Center for Disease Control and Prevention reminded that residents who care for their health can get the flu vaccine as soon as possible, especially those who have children, pregnant women, the elderly and other key personnel at home, and should take the initiative to vaccinate the whole family as soon as possible to build a family immune barrier to protect themselves and their families from the flu. You can go to the nearest community health service center (community health service station), the vaccination clinic of township hospitals and the health department of the hospital for vaccination. You can also make an online appointment through WeChat WeChat official account of Hubei Provincial Center for Disease Control and Prevention, and make an appointment in advance for the vaccination clinic and vaccination time, which is more time-saving and convenient.

How do students and parents take precautions?

The flu is coming, how can students and parents prevent it? Huang Li suggested that personal protection is the most important, and ventilation and disinfection should not be forgotten.

Students and parents need to do personal protection, wear masks, wash their hands frequently, pay attention to cough etiquette, try to avoid going to crowded places and avoid close contact with people with respiratory symptoms. If family members have respiratory symptoms, they should rest at home, observe their health, go to work and attend classes without illness, and wear masks when they are in close contact.

Children’s three meals a day need balanced nutrition, appropriately increase high-quality protein such as meat, eggs and milk, and eat more fruits rich in vitamin C. Ensure the length of children’s sleep, and adequate sleep has a positive impact on enhancing physical fitness. Primary school students should sleep 10 hours a day, junior high school students 9 hours and senior high school students 8 hours.

Always ventilate your home and keep the environment clean. Open the window for ventilation 2~3 times a day, with no less than 30 minutes each time. If it is inconvenient to open the window for ventilation, mechanical ventilation can be carried out with the help of an exhaust fan. After patients appear in the family, the surfaces of environmental objects contacted by patients can be disinfected with chlorine-containing disinfectant containing 250 mg/liter of available chlorine, or wiped with disinfectant wipes, and the surfaces of small items can be wiped with 75% alcohol.

Huang Li stressed that in addition, students and parents should be vaccinated as soon as possible. For high-risk groups such as young children who have not been vaccinated with influenza, vaccination as soon as the influenza vaccine is available can play a good preventive and protective role.

How do schools and kindergartens prevent it?

Li Fuqiang suggested that schools and kindergartens should do a good job in health monitoring, strengthen ventilation and disinfection, and build a strong immune defense line during the high-incidence season of influenza.

Schools and kindergartens should strengthen morning and afternoon inspections and full-day observation. Strengthen the registration system of absence due to illness, grasp the reasons of students’ absence, and find and report early. When influenza cases occur, patients should be allowed to rest at home to reduce the spread of the disease.

Schools should take advantage of students’ recess, physical education class, after school and other periods to strengthen classroom ventilation, so as to keep the classroom air circulating and fresh. Every morning, noon and evening, windows should be opened for ventilation, and the ventilation time should not be less than 30 minutes each time. Every day after school, the key places in the classroom should be cleaned and disinfected regularly. Nursery institutions should clean and disinfect students’ toys and other items every day.

Schools should publicize influenza prevention knowledge to teachers and students through radio, LED screens, blackboard newspapers, billboards, leaflets and lectures, do a good job in health education, help teachers and students develop good personal habits such as washing hands frequently, wearing masks and coughing etiquette, and improve their self-prevention ability. In addition, during the epidemic of respiratory infectious diseases such as influenza, schools should try to reduce or avoid large-scale gatherings and other collective activities to reduce the risk of transmission.

　　At present, the temperature in winter is changeable, cold and hot, and respiratory infectious diseases such as influenza enter the high-incidence season.

　　According to the press conference of the National Health and Wellness Committee, at present, with the continuous winter in various places, respiratory diseases have entered a period of high incidence. Monitoring shows that influenza is the main infectious disease of respiratory tract recently. In addition, there are rhinovirus, mycoplasma pneumoniae, respiratory syncytial virus, adenovirus and so on.

　　Recent monitoring in Guangzhou shows that acute respiratory infectious diseases mainly caused by influenza and mycoplasma pneumoniae are active, and respiratory infections caused by rhinovirus, adenovirus, respiratory syncytial virus and other common respiratory pathogens are intertwined. In particular, the level of influenza activity has increased significantly. At present, influenza A (H3N2 subtype) and influenza B (Victoria strain) are prevalent at the same time, and influenza is gradually entering the winter epidemic period.

　　How to judge which pathogen is infected? Influenza, mycoplasma pneumoniae and respiratory syncytial virus infection will all have symptoms such as cough and fever. How to distinguish them?

　　flu

　　Influenza is an acute respiratory infectious disease caused by influenza virus. Influenza patients and recessive infected people are the main sources of influenza infection, and the transmission route is mainly droplet transmission, but also through direct or indirect contact with mucous membranes such as mouth, nose and eyes.

　　The incubation period is 1-4 days, and the acute onset is mainly manifested as fever (high fever can occur in some cases, reaching 39-40℃), cough, sore throat, headache, myalgia and general malaise, and there may be symptoms such as chills, chills, aches and pains in muscles and joints all over the body, fatigue and loss of appetite. Some patients may be accompanied by vomiting, abdominal pain and diarrhea, which are more common in children.

　　Influenza patients generally have a good prognosis. After 3-4 days of onset, their body temperature gradually subsides and their systemic symptoms improve. However, children, the elderly, people with basic diseases, obese people and pregnant women are prone to develop into severe diseases after infection, so they should be treated promptly.

　　Vaccination with influenza vaccine can effectively reduce infection, even if it is infected, it can also reduce the incidence, and even if it is infected, it can also reduce the severity of the disease.

　　Mycoplasma pneumoniae

　　Mycoplasma pneumoniae is the smallest known microorganism that can live independently between bacteria and viruses. It is mainly transmitted by droplets and direct contact, and the population is generally susceptible, especially in children and adolescents over 5 years old. Usually, when the seasons change, for example, when summer turns to autumn or autumn turns to winter, there may be local and short-lived clustering epidemics.

　　The incubation period is 2-3 weeks, and the main symptoms are similar to those of most respiratory diseases, with fever and cough as the main symptoms. Generally, the cough is severe, and it may last for 1-2 weeks after the fever has gone down. After children are infected with mycoplasma, most of them show upper respiratory tract infection, a small number of them are lower respiratory tract infection (possibly bronchitis or pneumonia), and a small number of them may develop into severe mycoplasma pneumonia.

　　Generally speaking, after mycoplasma infection, there will be no repeated infection in a short period of time (1-2 months). It should be noted that if the symptoms of infection recur, it is often that the last mycoplasma pneumoniae infection did not heal, and the local lesions were not completely removed and secondary infection occurred.

　　At present, there is no vaccine to prevent mycoplasma pneumoniae infection. If you have fever accompanied by severe cough, you should see a doctor in time, find out the cause as soon as possible, standardize the treatment, and avoid using drugs blindly.

　　Respiratory syncytial virus

　　Respiratory syncytial virus is a common and highly contagious RNA virus. Spread through droplets and close contact, or spread through contaminated hands and surfaces.

　　The incubation period is usually 2-8 days, and detoxification can last for 1-3 weeks. Patients often have upper respiratory symptoms after infection, and the typical symptoms of children infected with syncytial virus are fever, cough, stuffy nose and runny nose. The typical symptoms of adult infection are very similar to the common cold, such as low-grade fever, cough, stuffy nose and runny nose.

　　Most patients’ symptoms will disappear spontaneously within 1-2 weeks, and a small number can develop into lower respiratory tract infection (i.e. bronchiolitis or pneumonia), which is more common in young infants. Clinical symptoms include cough and wheezing.

　　At present, there are no syncytial virus vaccines and special therapeutic drugs on the market in China. Syncytial virus can be repeatedly infected and easily spread at home, and infection can be prevented by strengthening personal protection and other measures.

　　Rhinovirus

　　Rhinovirus is one of the main pathogens causing the common cold. Mainly through direct contact and droplet transmission; Infants, the elderly and immunocompromised people are susceptible to rhinovirus.

　　The incubation period is 2-5 days, and the clinical manifestations are mainly runny nose, sneezing, throat discomfort, nasal congestion, cough, mild sore throat, low or slightly elevated body temperature, often accompanied by sinusitis and otitis media. Although rhinovirus infection can gain immunity, it lasts for a short time, so people can be infected with rhinovirus repeatedly.

　　At present, there is no specific prevention and treatment method. The patient’s condition is generally self-limited, with mild symptoms and can be cured in a week or so.

　　adenovirus

　　Adenovirus is not a new virus, it is a common virus that causes respiratory infection in children, and it is the main cause of community-acquired pneumonia in children. It can spread through droplets, close contact and fecal-oral route, and can also spread through water. Babies over 6 months old, school-age children and immunocompromised people are the high-risk groups of adenovirus infection.

　　The course of disease is usually 5-7 days, but the symptoms may last for up to 2 weeks, which may be complicated with bacterial infection. Symptoms vary according to the affected parts, and may include: fever, sore throat, runny nose, cough, earache, conjunctivitis (also known as "red eye"), diarrhea and hoarseness.

　　Adenovirus infection is mostly self-limited and supportive treatment is adopted. Antiviral therapy is usually only used for severe adenovirus disease, and most of these patients have impaired immune function.

　　At present, there is no adenovirus vaccine in China, and the prevention of adenovirus infection mainly focuses on hygiene, especially hand hygiene.

　　How to scientifically prevent respiratory diseases in daily life?

　　1. Wash your hands frequently. Wash your hands with soap or hand sanitizer and flowing water. Cover your mouth and nose with a handkerchief or paper towel when sneezing or coughing to avoid polluting your hands and the surrounding environment.

　　2. More ventilation. Keep the indoor air circulating, and generally ventilate 2-3 times a day at home in winter for about 30 minutes each time.

　　3. gather less. During the epidemic of infectious diseases in winter and spring, try not to go to crowded places and avoid contact with patients with respiratory diseases. It is recommended to wear masks when you need to go.

　　4. Drink plenty of boiled water. Keep the nasal mucosa moist, effectively resist the invasion of viruses, and also facilitate the excretion of toxins in the body and purify the environment in the body.

　　5. Eat a balanced diet and exercise properly to enhance your physical fitness (outdoor activities should be reduced in foggy days).

　　6. Vaccinate. Vaccine is an effective means to prevent related infectious diseases. For infectious diseases such as influenza, chickenpox and mumps, susceptible people can be prevented by vaccination in advance.

　　7. Once infected with infectious diseases in winter and spring, patients should take hospitalization or rest at home according to their illness and doctor’s advice, and avoid participating in group activities and entering public places during this period. Resume daily activities such as going to school and going to work after it is not contagious.

　　[Global Network Reporter Zhang Xiaoya] According to Agence France-Presse, the Brazilian government said on March 29th that China and Brazil had reached an agreement to trade in local currency instead of using the US dollar as an intermediate currency.

　　Agence France-Presse said that this agreement will enable China and Brazil, the largest economy in Latin America, to conduct large-scale trade and financial transactions directly, and exchange RMB for the real, and vice versa, instead of using the US dollar as an intermediate currency. The report said that the agreement was announced after the China-Pakistan high-level business forum held in Beijing. In January this year, the two sides reached a preliminary agreement on this.

　　"This is expected to reduce costs … … Promote bilateral trade and investment facilitation. " The Brazilian Export Investment Promotion Agency said in a statement.

　　Agence France-Presse said that China is Brazil’s largest trading partner, with bilateral trade reaching a record $150.5 billion last year.

　　Bloomberg reported on March 25th that before Brazilian President Lula’s visit to China, hundreds of representatives of Brazilian agricultural enterprises "flocked to Beijing" this week, seeking to increase export cooperation with China and attract investment. Reuters also said that the delegation visiting China is huge, including cabinet ministers, governors, parliamentarians and 240 business leaders. Most of Brazil’s beef, soybeans and wood pulp are exported to China. Brazilian Foreign Ministry officials said that Brazil hopes to expand its trade with China beyond the export of iron ore, soybeans, soybean oil and meat, and is ready to sign agreements on technology, innovation and sustainable development.

　　According to the news published on the website of the People’s Bank of China in February, recently, the People’s Bank of China and the Central Bank of Brazil signed a memorandum of cooperation on establishing RMB clearing arrangements in Brazil. The establishment of RMB clearing arrangements in Brazil will be beneficial to enterprises and financial institutions in China and Pakistan to use RMB for cross-border transactions, and further promote the facilitation of bilateral trade and investment.

As a means of transportation that relies on electric energy, it is essential to charge electric vehicles. However, different car owners have different ideas about the habit of charging electric vehicles. Some of them charge only when the power is running out, and some people charge frequently and charge every day. So, can electric vehicles be charged every day? The little expert made it clear once today and really learned it after reading it.

As for the way of "charging every day", it can’t be said that it is absolutely correct or absolutely wrong. After all, if the battery life of an electric car is only forty or fifty kilometers and you travel twenty or thirty kilometers every day, you have to charge it every day. Whether you can charge it every day depends on whether the advantages outweigh the disadvantages or the disadvantages outweigh the advantages. Let’s take a detailed look at the advantages and disadvantages of "charging every day" of an electric car.

Regarding the habit of "charging every day", what are the advantages of it compared with the need to use clean electricity to recharge? According to the expert’s summary, there are two simple and clear ones.

The first is to reduce the battery vulcanization reaction and slow down the battery aging speed:

What kind of battery is the fastest aging, that is, the battery with faster vulcanization speed, which leads to battery vulcanization, and the most important point is power loss. As long as the battery is discharged and not replenished in time, the sulfuric acid concentration of the battery is thin, and sulfide crystals will form, which will lead to battery capacity reduction and battery aging.

If the battery is charged every day, it can be replenished in time after discharge, and the concentration of electrolyte in the battery gradually increases, returning to the concentration before discharge, which can prevent the battery from vulcanizing and slow down the aging speed of the battery.

Secondly, there is no need to worry about the power failure halfway, and there is no need to take emergency treatment methods that damage the battery:

If the electric car is charged every day, there will naturally be no trouble in the middle of the road. As long as there is no electricity in the middle of the road, the emergency switch such as ACS provided by the manufacturer will not be used by the owner, and there is no need to worry about damaging the battery.

As for the ACS switch, it can still release electric energy when the electric vehicle shows insufficient power, but once it is turned on, it will release all the protection voltage of the battery, which is very harmful to the battery. If it can be used, try not to use it.

Talking about the advantages of charging every day, but since discussing this way, there must be advantages and disadvantages, otherwise there is no need to discuss it. Then, what are its disadvantages, you can also sum up two.

The first is the waste of cycle charge and discharge times of the battery:

No matter what kind of battery, as long as the cycle charge and discharge times are used up, the battery will be scrapped, and charging every day with enough electricity will inevitably lead to the waste of times, especially lead-acid batteries, which must be avoided. It only has about 300 charge and discharge times. If it is used once every three days, it can be used for three years. If it is charged every day, the usable time of the battery will inevitably be shortened.

Secondly, it is easy to accelerate the water loss rate of the battery;

There are two important structures in the battery, the first is the lead plate, and the second is the electrolyte. If the battery is charged every day, the battery temperature will inevitably rise, which will evaporate the electrolyte. If a battery is charged and charged infrequently every day, the water loss rates of the two will be obviously different. When the battery electrolyte is insufficient, the battery performance will be affected and its life will be shortened.

Through the above introduction, we can get an answer. It is not recommended to "charge every day" for electric vehicles. Of course, if the power of electric vehicles is not enough to maintain the battery life for 2 days, it can be "charged every day". Compared with daily charging, it is not perfect. The following experts share the correct charging method, which is conducive to improving battery life.

1. The power of the electric car is enough for more than 2 days. Don’t charge it every day. Recharge it when the power is about 20%.

2, equipped with a lithium battery, because the number of charge and discharge is more than 1000 times, you can charge according to your habits;

3. Charge electric vehicles to avoid sub-zero environment;

4. Every time the electric car is charged, the charger will continue to charge after it turns green to complete the floating charge;

There is no need to choose between the charging habits of electric vehicles. Whether electric vehicles should be charged every day depends on the battery capacity and battery type. Can electric vehicles be charged every day? Through the analysis, it can be seen that lithium batteries are completely ok, while lead-acid batteries have advantages and disadvantages. It is necessary to master the correct charging method according to the situation of electric vehicles and improve the battery durability. What do you think of this? Welcome to comment and exchange.
