Inspection items of various face masks quality inspection: filter efficiency test, quality test, tightness, air tightness, active carbon component test, microorganism test, ethylene oxide residue, dust resistance efficiency, filter element test, etc.
From August 1, 2009, gb2626-2006 respiratory protective equipment self-priming filter type particle respirator was implemented, which stipulated that the protection levels for particles were Kn90, kn95 and kn100. The protection levels of oil particles are kp90, kp95 and kp100. The filtration efficiency was 90%, 95% and 99.97% respectively. Kn100 and kp100 are of high protection level. According to the national gb2626-2006 standard, the filter elements of dust masks shall be printed with permanent identification: ‘gb2626-2006-kn100’ national standard, year number and protection grade identification. The higher the degree of protection and filtering efficiency, the higher the safety of the dust mask.
Protection performance for fine particles (PM2.5) The protection effect level is set according to the air quality category in the national air quality standard. The protection effect level is divided into four levels from low to high: Level D, level C, level B and level A. The corresponding use environment is as follows: Level D is suitable for moderate (PM2.5 concentration no more than 150 g / m3) and below pollution, level C is suitable for severe (PM2.5 concentration no more than 250 g / m3) and below pollution, and level B is suitable for severe pollution Dye (PM2.5 concentration no more than 350? g / m3) and grade A are used when PM2.5 concentration reaches 500? g / m3. Wear mask reasonably according to the standard requirements, which can reduce the concentration of PM2.5 inhaled to less than 75? g / m3, and make the air quality in the inhaled body reach good or above level.

BEIJING, March 8 — China’s gas sector exhibited a strong performance in the latter half of 2020 and medium-term growth will remain solid, according to the latest report from Fitch Ratings.
A recovery in industrial activity following coronavirus pandemic lockdowns and an exceptionally cold winter triggered a gas-supply shortage in late 2020, with strong demand leading to higher gas imports, the ratings agency noted.
However, last year’s gas-supply crunch was less severe than that seen in 2017, as national oil companies had moved some long-term contract deliveries to the winter to close the gap, according to the report.
The presence of new liquefied natural gas terminals, storage facilities and pipelines also helped to boost supply.
Fitch said it expects the medium to long-term gas supply to remain firm, driven by solid gas demand momentum.
“National oil companies are steering investment towards gas rather than crude oil in a bid to achieve carbon neutrality while safeguarding national energy,” it noted.
Under the epidemic, the new economy represented by the digital economy quickly fills up its seats to provide protection for everyone’s needs in life. “Cloud Office”, “Cloud Fitness”, “Cloud Concert”, “Cloud Recording”, “Cloud Release”…a business format about “cloud” became standard, which even detonated the term “cloud economy”. Although some people do not understand this concept very well, they have actually participated in it.
There is currently no uniform definition of “cloud economy” in academic circles. Some scholars define “cloud economy” as the economy of cloud computing and cloud services. Joe Weinman, the author of “Cloud Economics-Enterprise Cloud Computing Strategy and Layout”, explained that “cloud economics” is not an esoteric economic theory. The mathematical model is a vivid summary of the technological revolution, the core concept of “flexible cloud computing can effectively enhance the business value of enterprises”. The “cloud economy” we are talking about today mainly defines the business trend of enterprises and society under the massive application of cloud computing.
Since the country put forward the “Internet +” action plan in 2015, “Internet +” has been widely integrated into all walks of life, and the continuous innovation and integration of online scenes and offline scenes has promoted retail, finance, culture and entertainment, medical care, government affairs and other fields The rapid development and the “Internet +” that incorporates artificial intelligence technology is a technology cluster application. From pure software intelligence in the past to hard and soft intelligence today, it has changed people’s daily life and the overall industrial structure. Promoting the consumption upgrade of the market has also played a positive role and has become one of the signs leading the innovation and development of enterprises and society. In this special period of epidemic prevention and control, people rely on online work and life. It is generally believed that this is another rapid development trend in the Internet industry after SARS, which may provide more opportunities for entrepreneurship and employment, or even form new ones. The economic outlet of China-“Cloud Economy”.
Whether it is facial recognition and body temperature measurement equipment, or online check-in and attendance systems, all walks of life are launching various “cloud”-related products. When the market is advancing by leaps and bounds, we should maintain a rational mindset and be cautious and objective about the “cloud economy”. The popularity of the “cloud economy” during this period is mainly affected by the isolation of people at home during special periods, but the most fundamental driving factor is the rapid development of my country’s Internet and logistics industries in recent years. After the epidemic is over, it is a question mark whether the “cloud economy” can continue to be prosperous after being separated from the consumption environment of everyone’s home. In a short period of time, its impact on economic development and entrepreneurship and employment is still limited.
However, it should be noted that during this epidemic, consumers at home took the initiative to apply various “cloud economy” products, which I believe has provided a lot of support for the development of the “cloud economy” industry. The epidemic brings short-term pressure, but also brings opportunities for changes in the industry structure. Take “Cloud Classroom” as an example. The “Suspension of Classes without Suspension” this time is a test of online education. Some pain points such as poor self-control of students in online education have been exposed, and it is believed that the promotion of solving these pain points will become ” The next focus of “wisdom education”. In addition, the formulation and improvement of the “cloud economy” development policy will bring benefits to the better promotion of the development of the “cloud economy” in the future.
After this epidemic, we must not only see the reasons behind the “cloud economy”, but also find new “outlets” from the aspects of economic and social development and lifestyle changes. The government, enterprises and other diversified entities should increase integration and innovation mechanisms to truly endow this new economic form with more vitality and impetus.
Xi Jinping (R), general secretary of the Communist Party of China (CPC) Central Committee and chairman of the CPC Central Military Commission, visits the family of Tang Rongbin, an impoverished villager in the Luotuowan Village of Longquanguan Township, Fuping County, North China’s Hebei province. Xi made a tour to impoverished villages in Fuping County from Dec 29 to 30, 2012.[Photo/Xinhua]
Xi’s visit in 2012 pointed way for nation’s efforts in improving people’s livelihoods
The village where Gu Rongjin has lived for his entire life was on the verge of disappearing 10 to 20 years ago, with few means to support local livelihoods, its young people migrating elsewhere, the farmland unattended and the village school closed.
Luotuowan, a village in Fuping county of Hebei province, located at the foot of high mountains and only about three hours’ drive from Beijing, used to typify China’s rural poverty. Its residents lived on a meager per capita income of 950 yuan ($147) in 2012, and over 79 percent of its residents lived below the official poverty line.
On Dec 30, 2012, the village welcomed an important guest. Xi Jinping was on a tour to assess the real situation of China’s poor areas less than two months after he was elected general secretary of the Communist Party of China Central Committee.
Gu, 73, was then the Party secretary of the village and still has a vivid memory of Xi’s tour. “It was about 9 am, and many of us still hadn’t had breakfast. I remembered him lifting the pot lid to see what was being cooked. He wanted to see the real situation,” Gu recalled in a phone interview.
Sitting down with villagers in their rundown homes, Xi made a powerful appeal about the need to fight poverty.
“As long as we have confidence, even loess can be turned into gold,” Xi said during his visit to the county, in remarks that were published last week by Qiushi, the flagship magazine of the CPC Central Committee.
More than eight years on, as China is set to convene a grand meeting on Thursday in Beijing to summarize its poverty alleviation outcomes and honor outstanding units and individuals who have made key contributions to work on this front, analysts said Xi’s remarks in Fuping pointed the way for China’s poverty reduction effort starting from 2012, mapping out targets and priorities and laying the foundation for the targeted alleviation strategy.
China has secured a victory in its fight to eliminate absolute poverty in rural areas after having lifted nearly 100 million people out of extreme deprivation and ensuring that poverty was eliminated in all 832 national-level poverty-stricken counties by 2020.
“Xi’s remarks on his visit to Fuping emphasized a people-centered philosophy, a key development concept that was fully demonstrated during China’s anti-poverty campaign,” said Huang Jikun, director of the China Center for Agricultural Policy at Peking University.
His remarks also set the tone for the country’s efforts to develop a model for poverty alleviation, including steps to attract participation from private capital and focusing on the capacity building of impoverished groups and areas, he said.
The trip, which marked the beginning of China’s intensified poverty reduction efforts, was followed by a host of inspection tours made by Xi and meetings he chaired focusing on poverty alleviation in recent years.
Xi first set out the targeted poverty reduction strategy during his visit in November 2013 to Shibadong, an impoverished village in Hunan province.
At a national work conference on poverty alleviation in November 2015, Xi expounded on the goals, tasks and major measures in the fight against poverty and called for the use of targeted steps in the process.
He listed the fight against poverty as one of China’s three critical battles in a report to the 19th National Congress of the CPC in October 2017, saying that “poverty alleviation should reach those who truly need it and deliver genuine outcomes”.
China has secured a major victory that is worthy of esteem from the whole world and the country has reshaped the look of its poor areas, improved the conditions of production and life and improved the quality of life of the public during the process, Xi said at a key Party meeting in December.
According to the Voice of China’s “News Evening Peak” report, the National Bureau of Statistics announced on the 18th that the gross domestic product (GDP) in 2020 will exceed the 100 trillion yuan mark for the first time, with a growth of 2.3% against the trend. Become the only major economy in the world to achieve positive growth. With the new crown pneumonia epidemic raging around the world, the world economy is in a severe recession, and the external environment is more complicated and severe, how exactly is such a beautiful report card written?
2020 is an extraordinary year in the history of New China. In the face of severe and complex domestic and foreign environments, especially the severe impact of the new crown pneumonia epidemic, my country has submitted an excellent report card. The value was 101,5986 billion yuan, an increase of 2.3% over the previous year. The per capita GDP exceeded US$10,000, the economic structure continued to be optimized, and major engineering projects were basically completed. Ning Jizhe, deputy director of the National Development and Reform Commission and director of the National Bureau of Statistics, said: “The epidemic prevention and control work has achieved major strategic results. The main goals and tasks of economic and social development have been completed, and the completion is better than expected. The 13th Five-Year Plan was successfully completed. Officials, the victory of building a well-off society in an all-round way is in sight.”
A decisive victory was achieved in the decisive battle against poverty. Under the current standards, all rural poor people have been lifted out of poverty, 832 poor counties have all been removed, absolute poverty has been eliminated historically, and 55.75 million rural poor people have been lifted out of poverty. In 2020, the seven provinces (regions) of Guangxi, Sichuan, Guizhou, Yunnan, Gansu, Ningxia, and Xinjiang, where there are more poor people, the nominal growth rate of per capita disposable income of rural residents is 0.2-1.7 percentage points higher than the national growth rate of rural residents. The macro-control has achieved remarkable results.
Ning Jizhe said: “The quarterly economic growth indicators have returned to normal levels. In the fourth quarter, GDP grew by 6.5% year-on-year, 0.7 percentage points higher than the same period of the previous year. In 2020, 11.86 million new jobs were created in cities and towns across the country, exceeding the full year. Goals and tasks. In 2020, the consumer price index CPI will increase by 2.5% over the previous year, which is lower than the expected target of about 3.5%. In 2020, the national per capita disposable income will increase by 2.1%, which is basically in line with economic growth.”
The implementation of “six stability” and “six guarantees” has achieved remarkable results, and reform and opening up have created miracles of development. The benefits of multiple ownership enterprises have been improved. Ning Jizhe introduced: “In 2020, the added value of high-tech manufacturing will increase by 7.1% over the previous year, 4.3 percentage points faster than the added value of all regulated industries. The growth of foreign trade and foreign investment is better than expected, and global trade and cross-border investment will shrink sharply. Under the circumstances, my country’s total imports and exports of goods in 2020 hit a record high, an increase of 1.9% over the previous year. From January to November, the actual use of foreign capital increased by 6.3% year-on-year.”
In 2020, the total economic volume will exceed the one-hundred-billion-yuan mark. Ning Jizhe emphasized that this means that my country’s economic strength, scientific and technological strength, and comprehensive national strength have jumped to a new stage. It is of great landmark significance for building a well-off society in all respects and starting a new journey of building a socialist modern country in an all-round way. He pointed out: “Within 20 years, the total economic scale will be expanded to 10 times, and the achievements have attracted worldwide attention. In 2020, my country’s GDP will reach about 14.7 trillion US dollars, ranking second in the world, and accounting for 17% of the world economy. Around. In 2020, the per capita GDP will exceed 10,000 U.S. dollars for two consecutive years, stabilizing the ranks of upper-middle-income countries, and the development gap with high-income countries will continue to narrow.”
“You can go up to nine days to capture the moon, and you can go down to the five oceans to catch turtles” has become a reality. Technological innovation is becoming more and more active, injecting new vitality into high-quality economic development. my country’s industrial and agricultural production capacity has increased significantly. The total grain output hit a record high and continues to rank first in the world.
“The output of more than 220 kinds of industrial products ranks first in the world, and the added value of manufacturing is expected to rank first in the world for 11 consecutive years. The infrastructure continues to improve, and the total operating mileage of high-speed railways has reached 38,000 kilometers and the mileage of expressways has exceeded 155,000 kilometers. The number of 5G terminal connections has exceeded 200 million, ranking first in the world.” Ning Jizhe said.
More importantly, this has laid a solid foundation for my country to build a new development pattern. Ning Jizhe said that the key to accelerating the formation of a new development pattern in which domestic and international cycles are the mainstay and the mutual promotion of domestic and international cycles lies in tapping the potential of domestic demand, especially consumer demand. He introduced: “my country’s population ranks first in the world, and the middle-income group is also the largest in the world. In 2020, the total retail sales of consumer goods will be close to 40 trillion yuan, the final consumption expenditure will exceed 55 trillion yuan, and the total capital formation will also be close to 45 trillion yuan. This will help my country’s superior market size to be further brought into play.”
In the past year, the total retail sales of consumer goods continued to show negative growth throughout the year, down 3.9% from the previous year. However, the third and fourth quarters have turned positive, especially in the fourth quarter that the total retail sales of consumer goods increased by 4.6%. This rate has begun to approach the normal level of previous years. Ning Jizhe said that my country’s consumption is still the ballast stone for the stable operation of the economy! “From 2011 to 2019, my country’s consumption rate averaged 53.4%. In 2020, despite the impact of the new crown pneumonia epidemic, the final consumption expenditure accounted for the proportion of GDP. It still reaches 54.3%, which is 11.2 percentage points higher than the total capital formation, and is the highest level in recent years. Consumption is still the ballast stone for the stable operation of the economy.”
Ning Jizhe said that due to the epidemic, the growth rate of total social consumer retail sales fluctuated slightly in December, but from the overall trend, my country’s consumption was able to play a fundamental factor in economic development while increasing production and supply. Looking forward to 2021, there are many favorable factors that support the stable recovery of the economy. my country’s economy has a foundation and conditions to continue its steady recovery. Although the current pressure on the prevention and control of the epidemic to “import from external defenses and rebound from internal defenses” is still great, the fundamentals of my country’s long-term economic improvement have not changed.
“The obvious institutional advantage is the fundamental guarantee for economic stability and long-term social stability. Although the epidemic has spread in some places recently, the overall impact on the economy is controllable. We have the conditions and ability to control the spread of the epidemic and operate the economy. Stay within a reasonable range to achieve sustained and healthy development of the Chinese economy.” Ning Jizhe said.
