Why is it that "the core technology is subject to people is our biggest hidden danger"? Ni Guangnan, an academician of the Chinese Academy of Engineering, said at the 2017 China Semiconductor Market Annual Meeting held on March 23 that China’s network information field has been proved by decades of development practice that the real core technology cannot be bought, and the market cannot change it. . "China has developed to this stage, and even more important technical people will not give you, let alone core technology." Ni Guangnan said, "Because such technology is related to a country's core competitiveness, it is owned by the country. It is regarded as 'Dinghai Shenzhen' and 'National Weights', and cannot be opened and sold at will, so the most critical and core technologies must be developed and developed by themselves."
The real core technology is that you can’t buy it.
There is a view that there is no back door to the hardware and software that is common in the world market. Ni Guangnan denied this view with the relevant documents released by the WikiLeaks website.
The site disclosed a number of documents alleged to be the CIA hacking project, detailing how the authorities used hacking technology to break into smartphones, smart TVs, mobile apps and more. The document shows how the CIA exploited vulnerabilities in hardware and software systems, including system vulnerabilities in US companies, to invade the company without informing them of problems with their systems.
Ni Guangnan said that for such complex hardware and software, the designer only needs to set up many functions that are not disclosed for testing or maintenance. If necessary, some of them can be used as the "back door" of the intrusion. In short, the hardware and software that are common in the world market are backdoors.
Ni Guangnan also cited the "Zhongxing was punished" incident to emphasize the necessity of China's independent research and development of core technologies. Recently, ZTE was fined 8.9 billion U.S. dollars by the US Department of Justice for "violation of the US export ban." Since ZTE currently relies on the US side in core technologies such as chips, it can only swallow this bitter fruit.
In Ni Guangnan's view, in recent years, China has made great progress in mastering the core technology of network communication including CPU and operating system. However, in general, the core technology is still subject to people and has not yet formed its own technical system and ecosystem. In particular, there are some short boards (such as chip manufacturing, etc.), which are exposed in the "Zhongxing was punished" incident.
At present, because the gap between China and developed countries is not very large, and catching up quickly, some foreign multinational companies have begun to adjust their strategies, from the implementation of the blockade and ban on China to the implementation of "technical cooperation." However, many facts show that this kind of "technical cooperation" is often in its own name. In fact, it is only to put "Chinese-made" vests on foreign products to enter the Chinese market, and to induce China to abandon its efforts to continue to catch up. .
Ni Guangnan stressed that he hopes that "Zhongxing will be punished" can prompt people to recognize the historical lesson that "the real core technology can't be bought, and the market can't change it". In the development of core technology, it insists on its own research and development and its own development. Roads, don't turn because of temptation, leading to a failure.
Cleaning Brush
The brush is used to clean the dust stuck and accumulated in the gap on the surface of the fuselage. It can be used when the balloon cannot effectively remove large particles of dust.
Blow up a balloon:
Balloon blowing is a tool used to clean the appearance of the camera and lens. It is mainly used to blow away the fiber hair, dust and sand attached to the body or lens surface. Since it does not directly contact the camera components, it is unlikely to cause damage.
Blow up a balloon
The quality of the blowing balloon is very important, because after the rubber of the blowing balloon with poor quality is aged, there will be particles falling off inside, which will blow out with the air flow and fall on the lens surface.
