Chapter 1079 U, U, Erqu Wine
To be honest, comrades were confused at first when they heard Gao Zhendong's suggestion. What kind of operation was this?
They began to follow Gao Zhendong's words, drawing pictures on paper, thinking, and communicating from time to time.

Gao Zhendong didn't rush them or explain it to them, but waited for them to figure it out on their own. This technique was mainly clever, but the technical difficulty was not too high, and they should be able to figure it out on their own without explanation.

More than ten minutes later, in Professor Liu's expectant eyes, the two comrades from the Third Factory raised their heads and said, "Chief Engineer Gao, that's amazing!"

Professor Liu didn't understand why it didn't work the right way but worked the upside down way?

"Comrades, please explain this to me. I really don't quite understand this." Professor Liu was happy, but confused.

"Professor Liu, this is what happened. First of all, optical receivers are only found in simulated firearms, which can greatly reduce the cost of sensors. The size of a wall and a gun is a world of difference."

"Ah, I see. In this case, the sensor only needs to be the size of the diameter of the muzzle, or slightly larger?" Professor Liu could still estimate the size of the area.

"Yes, that's right. Moreover, through a suitable optical path system, the target can be projected onto different areas of the optical sensor. Although the area of ​​the optical sensor is not large, this is actually a way to dynamically simulate different impact points through the computer system!"

The comrades from the Third Factory are not just famous for nothing. They have dealt with optical systems before, and they have dealt with very advanced ones - photolithography machines.

They soon realized another benefit of this method. By imaging the target in different areas and using computer algorithms to perform reverse calculations based on the ballistic characteristics, they could roughly simulate different impact points. This idea was truly genius! Chief Engineer Gao's suggestion was truly amazing!
Professor Liu was a little confused about this, but he was very sure that since Gao Zhendong and the two comrades from the Third Factory said so, it meant that there must be no problem with this matter.

"That's great!" Being able to simulate the impact point to a certain extent actually means there is a way to use this ability to simulate the trajectory. He understands this, as it is his expertise.

"But..." However, the comrades in the Third Factory were still scratching their heads. There were some issues that they had not fully figured out, or they felt that the cost was too high.

"But what?" Professor Liu was startled. He was most afraid of the word "but".

"There is one thing we haven't thought about yet. This method means that we need to quickly recognize the image, or recognize the image from the background. This is difficult in color display, let alone black and white. It requires very advanced light sensors and high-speed computers to be responsible for this task. This is very expensive, and it is not certain whether there are light sensors and computers of this level."

Real-time image processing and recognition is a very difficult task these days, there is only one problem - it is difficult to calculate.

Professor Liu felt a little relieved, but also a little worried.

Don't worry, the principle is fine, and this provides a working basis.

My concern is that it might be too expensive, and high-speed real-time image processing sounds difficult.

"Do we have these components?" He looked at Gao Zhendong, a famous computer expert.

Unexpectedly, Gao Zhendong shook his head decisively: "No!"

This surprised the comrades, because they all knew that in this regard, if Gao Zhendong said no, then it really was nothing.

So what should we do? We saw hope, but it was shattered?

Professor Liu looked at Gao Zhendong's determined expression and suddenly realized that something was wrong. We felt that these components and equipment were necessary to achieve this capability, but this was not necessarily the case for Chief Engineer Gao. It was just like no one could figure out what was going on with this inverted light gun just now.

"Commissioner Gao, what can you do?"

Gao Zhendong smiled and said, "Actually, you shouldn't think about computers and electronic systems with human thinking. People rely on their eyes to see, but they don't see with their eyes. It doesn't matter what they look like."

It doesn't matter what you look like? Don't use your eyes to see?
"Chief Engineer Gao, I don't quite understand." The comrades from the Third Factory really couldn't figure it out.

Gao Zhendong said: "Don't think about using computers to recognize the target image and then determine whether it has been hit. That requires too much computing power. Why don't you put a feature in the target? The basis for the entire system to determine is not the image, but this feature!"

feature?!
"Yes! Why do we have to see clearly? As long as the optical sensor can determine that this is the target, it will be fine! We are still too young!" To be honest, in the hearts of the comrades in the Third Factory, Chief Engineer Gao is indeed amazing, but to what extent he is amazing, comrades who have not had in-depth contact with him do not know.

But at least these two comrades now know that the gap is really too big.

"Okay, I see. Color and shape can be used as features."

"No, right? In the current reality system, colors are not standardized, and it is difficult for sensors to judge colors. And the shape is stuck in the old problem of 'seeing with the eyes'..."

The two racked their brains.

Gao Zhendong said two words: "Frequency..."

"Frequency? Frequency..."

"I remember now! The target image block uses a specific flashing frequency! The human eye may not be affected too much and cannot distinguish it, but optical sensors and computers can easily distinguish it!"

Gao Zhendong smiled and said, "Yes, this is actually a simple optical coding technology."

Professor Liu felt like it was a fairy tale. How could he get straight to optics and communications?

But no matter what, he understood a little bit. With Chief Engineer Gao's careful analysis, he solved the problem!

And it sounds like a low-cost, high-effective solution!

With low cost and technical difficulty, he successfully realized all the firearm ballistic simulation and target strike simulation functions he wanted.

"Commissioner Gao, is this...solved?"

Gao Zhendong glanced at the two comrades from the Third Branch Factory and said, "You have to ask them about this matter. They are the ones in charge. Hahahaha, I am just a hands-off manager."

The two comrades from the Third Factory were now full of confidence: "It's solved! Chief Engineer Gao solved it beautifully!"
-
At about the same time, attention was focused on the southwest and the related northwest.

In a laboratory at Jincheng University, Teacher Gan raised his head from a pile of test records, his eyes full of shock and surprise.

A doubt in his mind was finally answered, and the answer shocked him immensely. It was not the kind of shock that came from being physically shocked, but genuine super surprise.

Ever since he came back from Beijing, he had been very curious about what element the amidoxime chelating resin that Chief Engineer Gao recommended using seawater for chelation tests chelated.

So after he was entrusted by the Sichuan Provincial Department of Mining and Metallurgy to return to Jincheng University to organize people to start research on amidoxime chelating resins, he tried several different routes of chelating resins mentioned by Chief Engineer Gao, but the one he personally worked on was not the one that Gao Zhendong pointed out could be used for gallium and indium chelation.

It was the variety that was chelated with seawater that he was personally responsible for.

This took him a lot of effort, after all, it was really impossible to get a large amount of sea water in Jincheng in the northwest.

Fortunately, Chief Engineer Gao gave a very clear route for this variety, and he managed to produce some samples of this resin relatively quickly. Although he didn't know if it would work, it looked pretty much the same as what Chief Engineer Gao had said.

Then he sent people to Songjiang to carry out experiments with these resins. This was very stressful for the comrades. According to Chief Engineer Gao's requirements, the adsorption time was as long as 40 days, which was very tiring.

Then we brought the tested resin back from Songjiang to Jincheng University for analysis.

And now, he has the analysis results in his hand.

Jincheng University has no shortage of analytical majors. This may sound like an economics or liberal arts major, but it is actually an applied chemistry major.

"No wonder! It's actually this thing."

He stared at the line of words on the analysis results with an excited expression.

——"U adsorption amount: 1.9mg/g (pH=6)"

It was indeed U! No wonder Chief Engineer Gao looked so mysterious at the time.

1.9 mg/g may not seem like much, but he knew one thing: the reserves of our U ore and another metal with similar uses are not high.

Even if it is researched as a reserve technology, it is very necessary.

Although this number is not large, it cannot be overstated by the fact that its raw material is seawater, ordinary seawater!
Over a fairly long period of time, there is truly inexhaustible sea water.

1g can absorb 1.9mg of U, which is incredible. Even if this thing is expensive, when you really need it, you can still get a lot of U if you are desperate.

The key is that this thing can be washed and reused many times!

Teacher Gan's hands began to tremble. Fortunately, he and his comrades from the Sichuan Provincial Department of Mining and Metallurgy had already reported the matter to the Defense Work Committee, and all people participating in the experiment had been arranged in advance, otherwise it would have been difficult to resolve.

He immediately rushed to the school's confidential room and made a phone call.

"Hello, leader. I am Ao Hai. I have officially checked it. It is Erqu wine. It tastes good!"

The name "Aohai" comes from "sea water" and "chelation", which is very rustic. No matter who it is, even if they eavesdrop on it, they will be confused.

As for Erqujiu, it comes from the atomic number 92 of U, 2, curved U, and 9. It can only be said that the comrades of the Defense Work Committee mainly used the arbitrariness when formulating the code word.

There was a loud noise of a chair being pushed on the ground from the other side of the phone. On the other side, where he could not see, the leader suddenly stood up from the chair, and slid back a long way using his knees to push the chair against his body.

The leader didn't care that his knees were hurting from the chair and asked, "Are you sure?"

"Sure!"
