We know that China has developed rapidly in the high-tech field in recent years. With the continuous service of aircraft carriers, -20. Dongfeng-41 missiles, it indicates that my country has achieved rapid development in the three major areas of sea, land and air. Perhaps such a great achievement has given many Chinese netizens an illusion that my country is now strong enough and no longer needs to rely on technology from other countries. But the answer is still somewhat cruel, because although my country has achieved rapid development in many fields, there is still a blank in the following four core technical fields, and it still needs to rely on Western technology support.
1. Smart phone chip
Although there are many domestic brands of smart phones in my country’s smart phone market, the most used are the US Qualcomm chips and operating systems. Obviously, if the US stops supplying, then domestic smart phones The mobile phone market is likely to face a difficult situation. Whether it is ZTE or Huawei, through so many lessons, we have deeply realized that in order to grow and develop, we must have our own chips.
2. High-end CNC machine tools
may be a vague concept for many people in manufacturing and creating countries. In fact, these are two concepts. First of all, the creative power must be more powerful. In fact, the manufacturing power is nothing to be proud of, because the real core technology is still mastered by the creative power, and the manufacturing power is only a processing factory. In the mechanical manufacturing process, CNC machine tools are obviously indispensable. If traditional manufacturing does not cooperate with high-tech means, the production schedule will always lag behind other countries. For example, Germany and Japan are the countries with top CNC machine tool technology in the world. Although my country has made some achievements in the field of machine tools, there is still a big gap between these top countries, and we still need to catch up.
3. car engine
We know that there are many brands of domestic cars, but whenever car friends complain about the performance of domestic cars, the key point is still on the engine. Either the power is insufficient, or the service life is short, easy to break, etc. So when everyone buys a car, those who have the money will choose imported cars, and most of the economy will choose joint venture cars. Because of the three major parts of the car, domestically produced seems to be still; behind foreign car companies. Therefore, in order to meet the huge domestic demand for automobile use, we have to introduce foreign engine technology. For profit, they set up engine production workshops in China, and each engine produced will produce patent fees. In the end, we have become part-time workers. Therefore, if my country's local car companies are to become stronger and go further, we need to increase research and development efforts, strive to develop engines with superior performance as soon as possible, break the monopoly as soon as possible, and achieve independence and self-reliance.
IV. Z1z lithography machine
used to manufacture high-end chips. Everyone knows that if you want to make high-end chips, a lithography machine is naturally indispensable. However, there are only two top lithography machines in the world, in Japan and the Netherlands, among which Sony in Japan and ASML in the Netherlands have almost monopolized all the core technologies of lithography machines in the world. Among them, the Dutch ASML occupies more than half of the world's lithography machine market share. All chip manufacturers involved use the lithography machine produced by the Dutch ASML. The Netherlands originally planned to cooperate with my country in lithography technology, but the United States has put pressure on the Netherlands to not allow them to sell technology and equipment. So we can only spend money on renting, and we can't research the core technology ourselves. We have always been subject to great restrictions.
