If a college graduate's graduation project is a nuclear bomb or even a nuclear reactor, it will definitely be considered a madman by ordinary people.

However, you can also see some third-rate tabloid news about a college student assembling a nuclear reactor in his garage or something.

This is the progress of technology, the initial development of nuclear bombs, it may take a long time, but after the accumulation of time, it will be easy for the later people to study it, and even in the developed United States and the Soviet Union, there is no need to test the explosion at all, as long as it is simulated by a supercomputer.

In terms of tank sights, although this disturbance fire control system sounds difficult, and even an introduction project with the L7 tank gun, in fact, this fire control system has long been outdated.

The advanced fire control system is a stable image, disturbance type fire control system, the biggest problem is the matching of the digital ballistic computer on board, and now, a machine factory has solved this problem, by the country's most professional computer to help, this kind of computer will be quickly made, then, with it to match, to add a point of light, is not particularly difficult.

Of course, even so, it is still too difficult for Xiaoyu, but this system is definitely not something she has to complete alone, there is Professor Cao behind her, Professor Cao will definitely give all kinds of guidance, and at the same time, there is Wang Xiaoqiang cooperating with the programming of the computer, and Qin Zhenhua is beside her, what is there not to do?

Of course, this graduation project will definitely be carried out in a machine factory, which means that after Xiaoyu comes back this time, a machine factory will be a major place of work for her, although there is still more than a year to graduate, before graduation, she will only return to the Capital Institute of Technology when she is in need, and most of the time, she will stay in a machine factory.

It also means that you can have more time with Brother Zhenhua in the future.

The premise of all this is that a machine factory accepts this project, and now, the main person in charge has made a decision, and the excitement in Wang Xiaoyu's heart is inexplicable.

Zhu Lao was beside him, glanced at Professor Cao, and then smiled, it seems that Professor Cao has a heart. That's a lot.

Qin Zhenhua spread his hands helplessly: "Professor Cao, your academy is too child's play, right?" ”

As soon as he said this, Wang Xiaoyu was unhappy and pouted: "What? You, an outsider, are you qualified to comment on the arrangements of our academy? ”

"Zhenhua is not an outsider, when the graduation project is completed, you can sign Zhenhua's name on the instructor in the back." Professor Cao said on the side.

Qin Zhenhua quickly shook his head when he heard this, okay, I'm afraid of you, sign my name, what does this mean? I don't want to be a nominal teacher in your college, I'm not even a college student, how can I be a nominal teacher in your college?

Lift me up.

The topic was quickly reversed by Qin Zhenhua, and he continued: "This kind of disturbance targeting system, after all, is still backward, and our second-generation tank still needs a stable image targeting system, how is the progress in this regard?" ”

The last time I went abroad, Professor Cao went out with him, and when he came back, he got his wish and bought a set of second-hand NM-60 four-shaft single-sided grinding machine, and even used the bonus of 10,000 marks that Qin Zhenhua got from Mercedes-Benz Heavy Truck Company because of the country's lack of foreign exchange.

Qin Zhenhua doesn't care about personal gains and losses, everything is in the interests of the country, and the help provided to Professor Cao is naturally to let Professor Cao complete the research and development of this project as soon as possible.

"This system is currently under active development." "However, so far, there is still one important aspect of the project that has not been overcome, so even if it is developed, it is still flawed. ”

"Low-light night vision?" Qin Zhenhua asked.

Professor Cao nodded, sure enough, he is an understanding person, as long as he says it, his heart is like a mirror.

Domestic tanks, for a long time, have not had the ability to fight at night, or in other words, they also have the ability to fight at night, relying on tankers, supplementing more vitamin A and eating more cod liver oil.

Technology is constantly evolving, but in China, it has always been outdated.

In fact, as early as the introduction of the 59 tank, the night vision device of the infrared headlights on the T-54 has matured, it is an active night vision method, at night, using an infrared headlight to illuminate the road, because it is not the category of visible light, it cannot be seen by the naked eye, but it can be received by the tank's sights, so, irradiating the past, reflecting back, the tanker can see everything in front of him clearly in the dark.

It's just that this method is quite primitive and backward, as long as there is an infrared receiving device on the opposite side, those infrared headlights, it is a way to expose their targets brightly, and the other party is accurate.

However, even such a device is not available in the country, and the domestic 59 tanks, which do not even have an infrared headlight, almost do not have the ability to fight at night.

It was not until the 69 tank that it began to be equipped with infrared headlights, and it somewhat had the ability to fight at night, which only solved the problem of whether there was or not.

The low-light night vision device has been a relatively mature night vision device developed over the years. Compared with infrared headlights, it does not emit any signal, only receives a faint light, and then constantly amplifies it, making this signal stronger, and you can see everything in the dark.

Unless it's absolutely dark, and you can't see your fingers, as long as there is a faint starlight, this night vision device will work.

"The low-light night vision device has now developed to the third generation." "The first generation, in the early 60s, used a multi-alkali photocathode, an optical fiber panel and a concentric sphere electron-optical system, and the first-stage single tube could achieve about 50 times the brightness gain, which was visible to the naked eye through the three-stage cascade. ”

"The second generation, the use of microchannel plate electronic multiplier, the gain of the first stage is as large as the original three, to achieve the revolution of low-light night vision devices, now most of the foreign products, or the second generation, but, to say advanced, is already the third generation."

"The third generation appeared in the development of semiconductor technology, and the development of gallium arsenide negative electron affinity potential reflection photocathode theory and the realization of the process triggered a revolution in the field of low-light night vision. Compared with the second-generation low-light night vision device, it has 4 to 8 times more sensitivity, 3 times longer lifespan, and has good observation ability in pitch black nights. ”

"As for us, we don't even have the first generation of products now." Professor Cao said: "In this way, even if our fire control system is developed, it will continue to retain the defects of night combat. ”
