China's 3G Chips Break Through US' Block

 According to an article in Hong Kong's "Asia Weekly", China's three-generation chips have changed lanes and overtaken the US Quartet Alliance. Since 2018, the United States has used brutal means to suppress the rise of China's high-tech industry, making China "lack of cores and souls" and the first wave of attacks on electronics, communications, mobile phones and other industries. China chooses to change lanes to overtake, relying on traditional wisdom, "he will do what he wants, and the bright moon will shine on the river", which is simply "you hit you, I hit me". As long as China finds new growth points in other fields, it can make up for losses in other battlefields.

Therefore, China is actively attacking the third-generation semiconductors or chips that have just started, the competition is not so fierce, and the technology gap is small. Its application range is new energy vehicles, 5G base stations, photovoltaics, wind power, high-speed rail, autonomous driving and radio frequency devices. These industries are also developing towards the economic model of clean energy, with huge future potential and ideal development direction.

China's technology changes lanes and overtakes, and takes the lead in moving towards technological independence in new fields under the trend of "reverse globalization" in the technology industry. In this way, the means and technologies that the United States can use to sanction and control the development of China's third-generation chips are also very limited, and China's emerging technology industry is ushering in a good opportunity to catch up and develop. According to the statistics of China Customs in the first seven months of this year, the export of new energy vehicles increased by 54% year-on-year, and the export of photovoltaic industry increased by 113% year-on-year, driving the national export to surge by 23.9% in July. BYD is fighting against Tesla, and China's photovoltaic industry has overwhelmed Germany. China has gained a firm foothold in the downstream industry of third-generation chips, and is ready to accelerate its efforts, change lanes and overtake, and break through the blockade.

After the US authorities' continuous suppression of China's technology industry, Chinese companies have changed their minds. They are no longer afraid. Therefore, it can be noticed that in the years after the 2018 technology war, China's industrial layout has quietly changed. This stems from China's unique industrial awareness. Since the second-generation chips are blocked by the United States or there are huge uncertainties, it is better to find new ones and start the third-generation chips, at least in other fields that can catch up with the international level. , and massively expand production, try to make the self-sufficiency rate as high as possible, and win in these industries to make up for the huge losses in electronics and mobile phone industries under the suppression of the United States.

Hong Kong and Taiwan media pay attention to the US chip bill, but the mainland is relatively flat. First, it is the second time, and there is no "surprise"; second, under the trend of anti-globalization in the technology industry, China's chip industry is forced to embark on independent and independent development. Import substitution road. China's new energy vehicles, photovoltaic industry, 5G base stations, wind power, autonomous driving, etc. will drive China's overall economic development in the next three to ten years as the third-generation semiconductor and chip technologies become autonomous and mature

The aviation technology behind ski jumping

 Among the wonderful ice and snow sports at the Beijing Winter Olympics, ski jumping is an extreme winter Olympic sport that combines speed, strength and courage. It is very popular among ice and snow enthusiasts from all over the world for its long jumping distance and graceful movements. The wind in nature is a ski jumper's closest partner in training and competition.

"Different environmental winds, different movement speeds, different body weights, and different flight attitudes will produce corresponding air changes. This is what professionals call aerodynamic characteristics." Aviation Industry Corporation of China Limited Air Yuan Li, president of the Power Research Institute (hereinafter referred to as the Aeronautical Industry Aerodynamics Institute) and China Ice and Snow Science Advisor, told the Science and Technology Daily reporter.

Yuan Li told reporters that after more than a year of wind tunnel-assisted training and computational fluid dynamics research, the Aeronautical Industry Institute of Aeronautics used aviation wind tunnel technology to make a historic breakthrough in the performance of Chinese ski jumpers. The athlete won the first place in the sub-station for the first time in the international points competition, and finally the Chinese ski jumping team got 3 "admission tickets" to the Beijing Winter Olympics.

Technology helps Chinese athletes "fly" higher at the Beijing 2022 Winter Olympics

"There is still a gap between China and the top countries of ice and snow eports!" Reporters often hear such a comment at the Beijing Winter Olympics.

Many ice and snow events in China started late and have a weak foundation, but at the Beijing 2022 Winter Olympics, Chinese ice and snow athletes have achieved many substantial leaps from "scratch" - not only to participate in the entire event, but also to achieve good results. The gap is narrowing, and the help of technology is indispensable.

"Secret Weapon" Special Wind Tunnel

How to let a group of athletes from "cross-item selection" quickly master the sport? How to make them better handle the wind?

Using artificial intelligence assistance system, real-time collection of athletes' jumping angle, aerial posture, speed, distance and other data, to provide better scientific and technological support to the coaching team... This is the chief scientist of the national key research and development plan "Science and Technology Winter Olympics", from Shanghai Sports Liu Yu of the academy, and what the team he is responsible for is doing.

Laiyuan National Ski Jumping Training and Scientific Research Base has overcome another difficulty: ensuring the "quantity" of training. In the past, Chinese athletes had only one option - training abroad, with high risk of injury and low efficiency. With the completion of the Laiyuan National Ski Jumping Training and Research Base, all the problems have been solved. The base is also equipped with the world's largest and China's first dedicated ski jumping wind tunnel laboratory, which is the "secret weapon" for improving the training level of athletes.
