The floating-point arithmetic mentioned by Wang Xuexin not only surprised Qiong, but also Turing, who was on the other side of the world, was surprised and happy when he heard about it.
If it can be said that the Eighth Route Army took the lead in relays before, it can be considered their luck, then this floating point operation is a real innovation and breakthrough.
Turing even wondered whether the Eighth Route Army had fully adopted low-speed computers...
"This algorithm seems to be a cost-saving innovation resulting from long-term and large-scale application!" Turing said: "If China's computers have this algorithm before it is developed, then it can only be said that their thinking
It’s so ahead of its time!”
No wonder Turing thinks so. This is the development law of most science and technology...In industrial development, people often produce machines first, discover its shortcomings during use, and then find ways to use them.
ways to address these shortcomings.
However, Huaxia violates this rule when it comes to computers: its computers are still under development and have not yet been put into use. This mature algorithm that can effectively save costs, improve parts utilization and expand the computing range has already been formed.
This surprised Turing, and he couldn't help but feel a little curious about this Chinese leader who was already famous overseas...
Wang Xuexin on the other side had already used the relay for "high fire".
Prior to this, the control of "high fire" was mechanical. Simply put, the control system of high fire was mainly powered by two pressure bottles to achieve control: the pressure bottle was connected to the "high fire" joystick and needed to be pulled.
Then open the valve to release the air pressure in the air pressure bottle to push the joystick to adjust.
This control method has many shortcomings, such as heavy weight, large space occupation, inaccurate control, etc. It is even difficult to stabilize the flight in the later stage... After the air pressure of the air pressure bottle is partially released, the pressure becomes smaller, and the same
The required control value cannot be reached within the preset time, so the flight becomes more unstable in the later stages.
This directly leads to the poor accuracy of "high fire". It really depends on luck or batch bombing to hit the target.
These problems are solved with the application of relays.
There is no need to bring a pressure bottle. Bring a storage battery and connect several relays to form a circuit to control an electric motor, and then the torque generated by the electric motor controls the joystick.
This not only makes the weight much lighter than before, but also makes the control more precise and timely, and will not change later. It not only reduces the cost but also improves the overall performance.
Wang Xuexin did not go to the three stores in person. He asked someone to send the relays and design drawings to Professor Su, who was making "high-effort" production improvements at the three stores.
When Professor Su received the items, he and He Zhimin were discussing how to further improve the accuracy of "high fire". They designed many solutions, including adding a barometer to the air pressure bottle to automatically adjust the data according to the air pressure in a timely manner. They found it difficult to
After doing this, I thought about adding a pressure bottle to keep it stable for a long time, etc.
But various methods were overturned one after another after experiments.
This is a characteristic of mechanical operation. It is impossible to be perfect, because every air pressure bottle is not the same. The pressure released by each "High Fire" during flight is also different, and even the strength required by the joystick is different.
Otherwise, there is no way to control it accurately at all.
But as soon as the drawings came, Professor Su looked at them and said to He Zhimin with a bitter smile: "Let's not worry about it, they have already solved this problem!"
With that said, he handed the drawings to He Zhimin.
"What? Solved?" He Zhimin still didn't believe it. How could such a complicated problem be solved as soon as it was said to be solved!
But after looking at the drawings, He Zhimin couldn't help but be convinced: "We have been thinking about improving on the original basis, but we didn't expect that others would stop using this method and directly change the mechanical control to electric control!"
Professor Su joked: "I'm talking about Lao He, we have to work harder! Otherwise, we old men here are just like idlers, doing nothing and not doing well!"
He Zhimin felt quite uncomfortable hearing this.
He Zhimin sometimes wonders, where is the problem?
Is it because Lao Su and I are not good enough and will be eliminated?
It shouldn’t be! There are not many people in China who can keep up with their combination!
After much deliberation, He Zhimin thought that the problem should be with Xiao Dongbei. His technology was updated so fast that they, the old men, could not catch up!
Wang Xuexin happened to find the Su Liguo that Wu Jin mentioned.
It took eight days. In Wang Xuexin's opinion, this speed was quite fast. After all, in this era of war and chaos, if you want to find a person, you don't just need to type in the computer...all kinds of information will come out like in modern times.
But this is just a superficial appearance.
When searching for Su Liguo, we actually took a detour and encountered the situation of "darkness under the light".
In fact, Su Liguo has been assembling radios for the Eighth Route Army in the base area.
For this person who was in the Eighth Route Army, the headquarters caused a lot of trouble because they did not start the investigation from within the Eighth Route Army first.
But it’s no wonder. Who would have thought that the person they are looking for is in the organization?
The headquarters used intelligence personnel to find them first from Shanghai.
First we found out that he had fled to Hangzhou, then to Taiyuan, and finally we found out that he had joined the Eighth Route Army in northern Shaanxi.
After learning about this, the chief was so angry that he almost cursed his mother, because one of the intelligence personnel was almost exposed (for intelligence personnel, every operation carries great risks).
Su Liguo was in his early fifties, wearing a washed-white and patched military uniform, a pair of black-rimmed glasses and a triangular beard. He was lean and looked malnourished. He couldn't help but cough twice when shaking hands with Wang Xuexin.
"Mr. Su, are you infected with the cold?" Wang Xuexin handed Su Liguo a cup of coffee. He knew that someone like Su Liguo, who came from a wealthy family and had studied abroad, would definitely not refuse this thing.
Sure enough, as soon as Su Liguo smelled the aroma of coffee, he swallowed his saliva, quickly held it carefully with both hands, and replied: "Oh, it's just the same problem I made when I escaped from Shanghai before, and it never got better! It's okay!"
Wang Xuexin nodded, feeling a little bit in his heart. This was the rich third generation of one of the best merchants in Shanghai. He didn't expect it to be like this now. The little devil is really harmful to people.
Then Wang Xuexin stopped beating around the bush and asked Su Liguo directly: "Mr. Su, I came to you this time to ask a question: Is it possible for us to produce our own electronic tubes?"
Su Liguo seemed to have guessed that Wang Xuexin would ask this question. He shook his head slightly and said, "Captain, although I really want to say it's possible, but..."
Needless to say what follows, Wang Xuexin knows what it means.
I saw some book friends in the comment area speculating whether Su Liguo is related to Su Xin... This is something I didn't expect, because Su Liguo has a real prototype, and I changed the name by one word. Most of the things written in the article are true, but
He did not join the Eighth Route Army but expanded his factory and business. The same surname as Su Xin can only be said to be a coincidence...
