The radar project team was in a difficult situation, and some of the young experts were almost hit hard. The Northwest itself is a new regime, everything is new, even the research institute is new, and the personnel are even new.

General conventional projects, such as ordinary heavy industry, machine industry, and even military projects, can use foreign experts, but some beyond the era of the project, it is not good, these must be kept secret, and even involved, is far beyond the concept of this era, just like radar, in fact, its principle is very simple, after the emergence of radio, understand the speed of the radio, you can find the distance of the other party from the difference and reflected waves. This is just an idea, but before I thought of it, it was a goalless, even if the northwest developed a radar in the future, if the other party didn't have this idea, it would be confusing, let alone follow up.

In this way, for a project that has a huge influence on the military, even if the progress is a little slower, foreigners who are not allowed to participate in the research and development, and even the slightest possibility of leakage, will be a huge blow to the northwest, even if it has been in China for a long time and has no tendency at all, it is no exception.

Participating in the radar project, are some of the northwest training, or students studying abroad, the huge team, the oldest is only 33 years old, the youngest is only 19 years old, none of them are from a professional class, the whole of China, except for a few fields, can rarely find a few professional backgrounds, China's foundation is too poor, although with the help of compulsory education and endless literacy, so that the northwest has a group of knowledgeable workers, but at the top, it is poor.

No way. The Northwest had no choice but to draw out some of the top literacy students and throw them into the research institutes, following the experiments of those experts invited from foreign countries to expand knowledge and expand space. Then, once you've learned a few, do your own research. This kind of method of pulling out seedlings and almost cramming is the only way to obtain high-level researchers in the Northwest, and it is also a choice in desperation, but those who can grow up with the research institutes in the Northwest and stand out among them, absolutely gifted, they can be said to have concentrated the best people in the field of radio and other fields, and their loss. It directly affects the subsequent research process.

Yang Yuanzhao has always been concerned about this project, after knowing this problem, he knows what is going on, using electron tubes does not mean that radar cannot be made, but it is more difficult, in order to produce suitable tubes, and form a complete set of systems, it must take a long time. Moreover, most of the radars produced are radars with fixed receiving devices. There is no such thing as an area or a bearing, just a distance.

The disadvantages of electron tubes, just look at the first generation of computers developed by the United States during World War II, which were the size of three rooms, all composed of electron tubes. Not only is the reliability very poor, but the engineers must be ready to replace the tubes at any time, and the power consumption is also amazing, which is almost an unsolvable proposition, the United States and the Soviet Union after World War II. A lot of effort has been put into it, and there has not been much progress in electronic computers, and the improvement is very slow, but when the transistors are used, this problem is immediately solved.

No matter how good the electron tube, it will gradually deteriorate due to the change of the cathode atom and chronic gas leakage, this problem is based on the characteristics of the electron tube, can not be solved, must take a long time and research to adapt, if it is not for the role of radar is too great, Yang Yuanzhao is also willing to develop in this direction, now since he has encountered a bottleneck, you can choose the transistor, he does not have this problem, in terms of reliability, the transistor is more than 1000 times that of the electron tube, and the power consumption, by saving a lot, Compared with the energy consumption tiger such as the electron tube, the energy consumption of the transistor is almost negligible, and after solving these two problems, the radar is really possible.

Compared with the electron tube, the transistor is more difficult to implement, because the material of the semiconductor, a key problem, is the purity of the material, to solve the problem of purity, the performance of the transistor, there is no way to solve, and even to a certain extent, even the electron tube is not as good.

Northwest in terms of materials, it can be said that beyond this era, although semiconductor materials are also just starting, but the previous experience of material manufacturing, so that the realization of semiconductor materials is relatively easy, and even, there is an all-in-one cheat, as long as through the laboratory, take out a relatively high purity material, you can gradually copy it, and finally reach the top semiconductor materials.

For this era, for the market, semiconductor materials, the most critical, but also the most difficult to solve the material problem, under the scanning and copying of the all-in-one machine, the biggest problem is solved, the biggest problem in the radio field, the problem of yield rate, in front of the all-in-one machine, is not a problem at all.

When Yang Yuanzhao proposed this solution, so that everyone was very interested, under the premise that the road of the electron tube could not be passed, it seems to be good to take another transistor road, the spirit of innovation in the northwest has always been there, Yang Yuanzhao in the field of materials and technology, but there are countless magical precedents.

Hearing is false, seeing is believing, Yang Yuanzhao personally led engineers and scientists to manufacture transistors, in the materials laboratory, all kinds of latest machines, although the principle of transistors is more in-depth than that of electron tubes, but the basic characteristics are still about the same, but more refined and pure, in the semiconductor materials that have been prepared for a long time, the use of machines in the laboratory, when a transistor was made, and after the experiment was successful, the entire radar research team was a sensation.

After replacing the electron tube with a transistor, in the area where the transistor is located, the life has been greatly extended, and it has not reached a thousand times that Yang Yuanzhao said, but it is almost the same, especially the consumption of electrical energy has been significantly reduced, compared to the electron tube, the electric energy consumed is almost negligible, the most critical thing is that the electron tube, after the electric power heating wick, can play a role, the computer and radar with the electron tube as the main unit must be turned on and preheated, before it can play a role, this time, less than ten minutes, It takes more than half an hour, and if the tube bursts or breaks in the middle and needs to be replaced, it will take longer.

In the middle, the transistor does not have this problem, almost after it is turned on, it is the maximum effect, which is for the military, which requires a long time to turn off and turn on the radar instantly, on this point, the transistor beats the tube.

Looking at a test passed, especially in many projects, have shown far more than the strength of the tube, everyone is excited, the study of the tube has fallen into a bottleneck, can only rely on the improvement of technology and slow research, familiar with its advantages and disadvantages, to promote the improvement of the reliability of the tube, but everyone knows, unless there is a big systematic change, otherwise the tube application is like that, but the transistor is different, in just appeared, in many ways, completely beyond the tube, As long as we continue to follow this research, gradually improve the quality of transistors, and make practical radars, it is almost easy to get them.

Radar, which the military values the most, has a huge role in the army, navy, air force, and even special operations, non-weapon equipment, the military boss, almost at any time, the previous stagnation is just no direction, can only use time to grind, now there is a new direction, new materials are also available, the passion for creation, suddenly burst out. Suddenly, radar research, which could have been in a state of stagnation, suddenly changed from the initial state of research to a state of rapid development because of a small change, and even as long as the type and number of transistors were sufficient, reliable testing machine radar may appear in a short period of time.

Such a discovery, so that the researchers are very excited, the radar laboratory, after maintaining enough personnel, put most of the energy into the research of materials and transistors, one by one can replace the transistors of the tube, came into being, the work of radar has also changed from a state of stagnation, to a state of gradual progress, included in the first five-year plan, the entire research time is tentatively set for 2 years, within 2 years, will produce results, a number of usable radar, instead of the current laboratory, still in the initial state of the prototype, It can only work in fixed and demanding conditions.

The semiconductor project, with the help of the east wind of radar, with the name of derivatives, entered the process of research, which is equivalent to sparing a big circle, Yang Yuanzhao tried his best to use the method of participation, the reason is that the northwest is mature, unless it can come up with real evidence, the whole northwest is more advocating the actual effect and the eyes can see, the calculated future, so that the northwest will accept, can not carry out the project.

This result makes Yang Yuanzhao helpless, and it is extremely happy, what does this mean, the northwest is mature, and it is no longer the northwest that relies on his separate guidance, and it may take a little detour, but the current strength of the northwest is also bearable, as long as the general direction of development is right, some detours that seem to be now may become the foundation of another road in a few decades, and it is not certain that Yang Yuanzhao only has 100 years of foresight, and now, because the butterflies in the northwest are getting bigger and bigger. It became ethereal, and such a big change had occurred, let alone anything else.

The radar project is already the last project of the First Five-Year Plan, which is more or less a bit of an advanced project, and also represents the peak of innovation in the northwest after eating through the world's scientific and technological achievements and the new technology brought by Yang Yuanzhao, in the future, with radar as the core, with the electronics industry as the leading electronics industry, it will surely achieve tremendous development, and even in the future the completion of the First Five-Year Plan, the research of transistors, relying on radar to reach a certain height, it is natural that various industries relying on chips will appear, such as numerical control, such as battlefield real scene system, Another example is avionics integrated control, which is a system engineering from design to military, production, machine manufacturing and many other fields, and it is also the foundation for the future prosperity of Northwest China.
