Chapter 463 They are robbing!
When a flame burns, it will simultaneously produce infrared radiation in three bands of 2.1μm, 2.7μm and 4.3μm. A two-color sensor can more accurately determine whether there is a fire.
In his previous life, Gao Zhendong had seen equipment that used 4μm band infrared detectors to detect wildfires. But having said that, if wildfires were allowed to burn freely for several months and a half like those in Citi Country and Kangaroo Country, In fact, it doesn't make any difference whether it is detected or not.
Of course, if you want to achieve the best results, Gao Zhendong has seen it in his previous life. Our terminally sensitive bombs have solved the problem very thoroughly. Infrared, millimeter wave, and laser are used together. It is very visible. It's clear, and it's locked tightly, but we don't have that condition now, right?
There is a description that is very suitable for engineering implementation.
You get what you pay for, you get what you pay for, you get what you pay for, you get what you pay for.
Now Gao Zhendong only costs one penny, so it’s not like he can’t use it.
Gao Zhendong said to Lu Gong: "Mr. Lu, we are the destroyers of design, not builders or saviors. Some of the requirements of the former are not as high as the latter two."
To save people, you cannot take a sufficient dose of medicine twice for the same disease, but for killing people, occasionally hitting the same target twice is not a big problem.
After listening to Gao Zhendong's words, Lu Gong smiled and said: "Mr. Gao, that makes sense, haha. Then this infrared band detector that is sensitive to flames."
Gao Zhendong knew that he had guessed it, and he also laughed: "Well, mercury cadmium telluride has a characteristic, and its sensitive band can be obtained by adjusting the crystal composition ratio."
Lu Gong and Professor Luo both laughed, Gao He always takes on assignments and is really well prepared.
"Then I will go back and simulate the control logic first. If the effect can be achieved by using logic control, that would be the best."
Computers are the best way to implement algorithms and logic, not equal to algorithms. and logic must be implemented by computers, especially some simple control logic.
What Lu Gong meant was to first see if he could solve the problem at the lowest possible cost without increasing the complexity of the equipment.
If that doesn't work, consider asking Gao Zhendong for infrared materials.
Gao Zhendong nodded: "No matter what the results are there, I will make a batch of suitable mercury cadmium telluride crystals for you first, so as not to delay your progress. Even if they are not used here, they will be used elsewhere. It’s also useful, haha.”
It can also produce a batch of infrared-sensitive materials. Lu Gong was very satisfied with this and put forward other ideas of his own: “I have analyzed the vulcanization under refrigeration conditions. The lead sensor seems to be able to basically meet the requirements. I will also try refrigerated lead sulfide first. After all, it is cheap.” It is that advanced means can solve the problem better and more conveniently, but this does not mean that advanced means must be used.
Gao Zhendong thought for a while: "Try it, but don't force it. If you are reluctant, just use cadmium mercury telluride. The extra money will be spent, and you don't have to worry about the detection."< br>
Compared with whether to penetrate 80mm or 100mm, Gao Zhendong is more concerned about whether he can see clearly or aim accurately. Mr. Lu thought it was a good thing to be cheaper, but Gao Zhendong still warned him not to put the cart before the horse.
Lu Gong nodded: "Okay, I will pay attention to it. If there are too many other costs to pay, or the performance deviates even a little from the requirements, I will still use cadmium mercury telluride."
After meeting each other, Gao Zhendong left Beijing University of Technology. He had come to class today and was busy doing scientific research.
When Gao Zhendong got on the bus, Professor Luo was still telling him: "Mr. Gao, don't forget to ask me about that technology."
Back to the third rolling mill , Gao Zhendong called Mr. Xiang from the Institute of Chemistry.
The technology he thought of for Professor Luo that might be useful in increasing the mass and density of the charge was the twin-screw extruder he had proposed to President Xiang.
Twin-screw extruders, or twin-screw extruders, are used to extrude plastics at Mr. Xiang’s place, but the uses of this thing go far beyond extruding plastics.
Gao Zhendong knew about this thing from the propellant forming process. From this, he knew that this thing is actually quite versatile and is widely used in the forming of pyrotechnics.
Mr. Xiang received the call and was very happy to hear Gao Zhendong’s request. He immediately gave him the contact information of the comrade who built the twin-screw extruder.
One day later, Professor Luo received the information on the existing twin-screw extruder from Gao Zhendong.
"First, this thing is good. It has continuous discharging, less online material, high efficiency, and the mixing effect is far better than kneading, single screw and other methods. The materials are evenly distributed and the particles are small..." After reading, Professor Luo immediately went to find The National Defense Working Committee is here. The coordination of this thing depends on the National Defense Working Committee. If improved properly, both the quality of the charge and the density of the charge can be significantly improved.
Even a few points of improvement are very valuable. For the same charge, the charge density has a direct linear positive correlation with the armor-breaking power. If the density increases by a few points, theoretically The armor-breaking power will be increased by several points accordingly.
The uniform charge and fine particle size are beneficial to the full reaction of pyrotechnics and the generation of stable detonation waves. These can improve the armor-piercing power bit by bit.
Under the premise that the resource conditions are certain, the increase in armor-piercing power is due to these comrades squeezing it out bit by bit from all aspects.
I really don’t know where Mr. Gao found this thing. It can solve his problem so well.
He only found out the answer to this question later, after the relevant origins of the twin-screw were made public.

Somewhere in the north, Comrade Sergeyev, who is responsible for non-military product trade with southern comrades, looks at a list of product imports that Petrovich brought up Apply to sulk.
“Comrade Petrovich, look, what bad news have you brought me again. Operating system? What the hell is this? Why should we spend money to buy this? I can’t find any clear Program for specific purposes? ”
"Comrade Sergeyev, this is what our computer experts requested by name. I don't know how the comrades in the south recommended this thing to them, but they are like crazy and demand that we must do it." Purchase a sufficient amount of installation media.”
Just as we used to sell software on floppy disks or CDs, comrades from the Ministry of Foreign Commerce now sell tapes.
“Oh my gosh, look at the price. It’s almost 20% of the price of their expensive computer! It’s just robbery! Robbery! You know, selling this for a tape The price is a gross violation of the rules of fair trade! We spent so much money and we can’t even see a screw!”
This complaint is of no use. This ratio is actually normal. . In the late 1990s and early 21st century, when Juhard's Win series sold for 1,998 yuan, the price of mainstream computers was only 10,000 yuan. Based on this calculation, the price of our foreign trade department is actually very reasonable.
Petrovich shrugged: "Comrade Sergeyev, this is a technical product. This is how we sell it to them, and it is normal for them to sell it to us this way."
Sergeyev's eyes widened and he looked at him with a bull-like look: "My dear Comrade Petrovich, do you remember what I once said? The list of high-tech products imported from the south, I I don’t want any more!”
“Okay Comrade Sergeyev, our scientist comrades will meet your requirements, but now, I think we have to meet their requirements first. Isn't it?" Petrovich said calmly and objectively, even a little bit mockingly.
Petrovich, who finally got the signature, walked out of the office happily, while Sergeyev looked at the nib of his pen that had split due to excessive force and got angry: "Oh my God, there really is no one Good news! No, I have to add some strength!"
After that, he opened the drawer and took out a bottle.

Mr. Seine on the Seine River maintained his "elegance".
He smiled while reviewing the memorandum of understanding between the two parties on the import and export of operating systems.
"Le Goff, I think we have to work hard. The Lion of the East has impressed us again. Apart from primary agricultural products from the colonies and primary industrial products produced in our own country, we actually have nothing worth buying for them. , This really makes me very frustrated.”
Le Goff said: “Mr. Senna, it’s not that we don’t have any, but the Technology Control Committee has strictly limited the technical projects that we can use for trading. Under the circumstances, I think you have done your best."
"Thank you, your words really make me happy. Look, what they sell to us is a computer, a special steel, and a software system. What we sell to them is grain and urea... Mr. Legoff, tell me, what’s the point of selling urea to them after we buy their urea steel?”
Compared with us, Gallic Chicken's sources of chemical raw materials at this time are much wider and the quantity is larger. It is not surprising that it can export urea to us.
Le Goff thought for a while and rubbed his nose: "I think at least we have increased the volume of international trade. Moreover, our tax bureau has also received taxes, hasn't it?"
Senna nodded: "Legoff, you always make people feel happy. Okay, I don't feel so uncomfortable anymore, everyone has a bright future."
With ridicule, Senna handed over the memo in his hand He signed it and handed it to Legoff.
"Okay, you go ahead and do this and turn the memorandum into a contract as soon as possible. Compared to Citigroup, at least the price of the Orientals is much more reasonable. Damn it! Citigroup doesn't even have this thing!"
The famous Unix appeared in the 1970s, and even its predecessor, the Multics project, only appeared in 1969. Before that, none of Citigroup's computer operating system projects could compare with the current operating system.
Thinking that Citigroup was lagging behind the Orientals in this regard, Cena couldn't help but feel really happy. Thinking about John Bull, too, Mr. Cena felt as if everything was not unbearable.
