China's strength in these years of rapid progress, we have reached the point of world leadership in many areas, looking back on the years of hard struggle, China has today's glory, can be said to be very difficult, now China has become the world's second-largest economy, has become the world's attention to the existence of the countries of the world, although today we have a lot of technology, still need to rely on other countries, but We are still breaking through this dependence, get rid of the constraints, and fully realize the Chineseization.
What are the technologies that are more advanced in China than in the United States?
One, China's high-speed rail
We all know that the high-speed rail is not actually the earliest in the development of China, but Japan and Germany, these two countries can be said to be the first development of high-speed rail countries, which has a lot of core technology, China began to develop high-speed rail, and not too much of their support, and now China has a completely independent production of high-speed rail technology, after all, now the total mileage of China's high-speed rail has been the first to develop high-speed rail, but now China's total mileage of high-speed rail has been the first to develop high-speed rail. After all, today China's total mileage of high-speed rail has become the world's first.
Two, China's infrastructure
We all know that China's infrastructure engineering team has always been called by many people as the devil of infrastructure, and China's infrastructure engineering team has built a lot of projects that make the world amazed, including the world's largest hydroelectric power station Three Gorges Hydroelectric Power Station, as well as the world's longest cross-sea bridge Hong Kong-Zhuhai-Macao Bridge, and of course there are many more examples of our China's infrastructure engineering technology is deservedly the world's first.
Three, China's quantum technology
In recent years, quantum technology is considered one of the most urgent needs of mankind to solve the technology, quantum technology can be said to be the future of mankind, and quantum technology is divided into a lot of areas, including the field of quantum communication is one of the most critical areas, China has always been the world's leader in the field of quantum communication, including the launch of our Mozi communications satellite.
Four, laser technology
As early as ?2013? the Chinese Academy of Sciences announced that China's deep ultraviolet solid-state laser source series of equipment through the acceptance of China's deep ultraviolet solid-state laser source series of equipment, so that China has become the world's only country capable of manufacturing deep ultraviolet solid-state lasers.
And the U.S. research in this area can be far behind China, until 2016 the United States officially developed the KBBF crystal, at the time there is a very joyful-looking news: the United States to break through the Chinese blockade successfully developed the KBBF crystal.
V. Cryptographic security technology
China's cryptographic security technology is ahead of the world. In 2005, Chinese scientist Wang Xiaoyun shocked the cryptographic community by cracking the SHA-1 algorithm, which is regarded as one of the most secure international passwords.
It is important to realize that SHA-1 was designed by the U.S. National Security Agency (NSA) and is the most frequently used cryptographic algorithm in the United States.
And Wang Xiaoyun's operation directly made the U.S. government announce that it would stop using all SHA-1 algorithms in the next 5 years, and then Microsoft, Google and other U.S. companies also announced that they would stop using the SHA-1 algorithm to ensure the security of their browsers.
This is the second international cryptographic algorithm that Wang's team has cracked in this decade. In 2004, they cracked the MD5 cryptographic algorithm, which for a long time has been recognized as the world's most advanced and secure international general-purpose encryption algorithm.
After cracking these passwords is not enough, she and the domestic cryptography experts together designed: the first hash function algorithm standard SM3, this algorithm has been widely used in various important areas of China.
Information security is crucial in the Internet age, and China's achievements in cryptography are equivalent to mastering one of the sharpest swords and strongest shields.
Sixth, large-scale high-speed wind tunnel technology
Wind tunnel laboratories, as the name suggests, are laboratories that simulate the flow of gases around a vehicle by artificially generating and controlling airflow.
The wind tunnel data provided in the development of aircraft and the aerospace industry has an irreplaceable role, because of the importance of the wind tunnel laboratory, once rumored: what kind of wind tunnel, in order to have what kind of airplanes, airships, rockets, missiles.
China has independent intellectual property rights of the 265-meter-long JF-12 shock wave wind tunnel, has represented the international leading level of high ultrasonic shock wave wind tunnel.
