Marconi nodded and replied, "Mr. President, I know this, but what does this have to do with the instrument you are talking about?" ”

Zhang Yi said in a deep voice: "Actually, the instrument I am talking about has a close relationship with the Doppler effect, his name is radar, I call it a radio wave transmitter receiver, its working principle is to use radio waves to find the target and determine his distance and even speed, you as a leader in the radio field, you must be very clear that the rate of radio is fixed, and all their bands are also fixed, so that in theory, it is absolutely feasible to measure the position and distance of the target with radio waves, but, There is no research on this yet! ”

Marconi frowned and asked: "Mr. President, I understand what you mean, but the technology you want you to talk about is only afraid that it will be difficult to achieve in a short period of time, which involves a lot of technical difficulties, and I have also had the idea of using radio waves to prevent collisions between ships or ships and icebergs at sea, but the emission of radio waves is very simple, but it is a very difficult problem to accept and analyze." [Ran^Text^Library] []. [774] [buy]. [com]”

Zhang Yi smiled slightly: "Mr. Marconi, I know that there is a certain degree of difficulty in this, but this problem is not unsolvable, his problem is whether we have gathered enough experts around us to deal with this problem, and I know that in Europe there has been a very in-depth study of electromagnetic waves, many of which are designed for electromagnetic wave research, for example, vacuum transistors, such as instruments that enhance the signal emitted by electromagnetic waves, As long as we concentrate the recent electromagnetic scientific research technology, it is still very possible, although you can rest assured to boldly develop, we will do our best to solve these problems for you! ”

Marconi nodded, and replied, "But, Mr. President, although this is somewhat important, I do not see that he will be of much help to your country at the moment. In my eyes, he's not even as good as the walkie-talkie we're working on! ”

Zhang Yi said with a smile: "For daily life, it may not be important, but for military defense, it is extremely important, and you also know that aircraft have begun to be widely used in warfare." With their superb speed, as well as the characteristics of their flight, they have almost no natural enemies in war. It has a huge destructive power and can even change the course of a war! My goal is to use it in the war, so that we can detect the invading enemy aircraft in the shortest possible time, so as to quickly respond and react! Isn't it important that this is related to the life and death of a country and the success or failure of a war? ”

Marconi's eyes lit up, if what Zhang Yi said was true, then the radar would have a huge impact on future wars. This will be an epoch-making weapon of war, although he cannot directly hit the enemy, but he can help the army to change the tide of battle to the greatest extent!

Marconi said in a deep voice: "Okay, Mr. President, we have settled this project, but I am afraid that it will be difficult to develop it within the time specified by you just by relying on the Radio Research Institute, it is too difficult!" ”

Zhang Yi smiled: "Mr. Marconi." Didn't I say that I will do my best to help you, our military research institutes, all our university research institutes, even Putian University and the Chinese Academy of Basic Sciences can join in, I believe in pooling the strength of everyone. There are no technical difficulties that cannot be overcome, and I believe that in five years, we will definitely be able to develop radars for use in warfare! ”

Putian University and the Institute of Basic Sciences of the Republic of China!

Marconi knew the weight of scientists in both institutions, where big names like Albert Einstein and Planck were in charge! With their help, it is really possible to develop this instrument!

Xu Huaijin on the side was really surprised, this big president really dared to think of anything! Development of radar. If the radar detects the plane out of line of sight and determines its distance and flight speed, if this technology is realized, the plane will soon be unlucky to arrive home? Think about it, hundreds of anti-aircraft guns, thousands of machine guns, all together to carry out directional strikes on the planes in the air, the unsuspecting planes are not beaten into a sieve, no, to pieces!

Moreover, not only anti-aircraft guns and machine guns, now the research of the third generation aircraft has reached the most critical moment, once the problem of the impact of the recoil of the machine gun on the aircraft is solved, the third generation aircraft with air combat capabilities will become a nightmare for the second generation aircraft, and it is definitely not a dream to destroy ten!

Xu Huaijin has already begun to imagine the tragic situation when the imperial planes invade the territory once the radar equipment is in place!

Xu Huaijin's respect for the instructor has reached the point of no return.

While several people were communicating with the Radio Research Institute on some key issues of radar technology, a guard hurriedly ran in!

"Report!"

Zhang Yi and Xu Huaijin were stunned, when the two of them had a technical discussion with the scientists, there were very few people below to disturb them, and it was even rarer to break in directly!

Zhang Yi's face sank and asked, "What's the matter, didn't I tell you, when I was conducting a scientific research institution, I didn't allow any of you to break in private, and you all turned a deaf ear?" ”

The guard was sweating profusely and said, "President, Chief, if something big happens, Premier Xu ordered me to go back to you immediately, and there is something urgent to discuss!" This, Premier Tang and President Liang and others are already waiting for you! ”

Zhang Yi and Xu Huaijin's hearts jumped, what happened, they actually worked Tang Shaoyi and others so anxiously, waiting for them to go back in the presidential palace?

Xu Huaijin said in a deep voice: "Instructor without further ado, let's rush back immediately, Shaochuan has always been a very stable person, he is already so anxious that his eyebrows are burned, it seems that the matter is not small!" ”

Zhang Yi nodded and said to Marconi: "Mr. Marconi, this matter is going to trouble you, I hope I can see our results as soon as possible, something happened to the presidential palace, I need to rush back immediately!" ”

Zhang Yi shook hands with Marconi and the others to say goodbye, got out of the Radio Research Institute, boarded the car, and rushed straight to the presidential palace.

In the car, Zhang Yi asked in a deep voice: "Tell me, what happened, so anxious?" ”

The guard replied: "President, it was something happening in Java, I heard that there was a large-scale riot in Java, and the Japanese colonial army directly dispatched troops to fight against the local Chinese, and the Chinese suffered heavy casualties, and preliminary statistics show that at least hundreds of people died in this riot, and countless ...... were injured" (to be continued.)
