Chapter 452 The error is huge
Speaking of this, Liu Haizhong also showed off his IQ: "Also, if you don't know how to calculate, don't calculate! It's 35 yuan 2! It's not 45 yuan 2! Why is there such a big difference? I see, the second and third children are so stupid, they just follow you! Fortunately, the boss follows me, otherwise this family would be dead!"
As for Liu Haizhong, he really loves the boss. , it’s just that if this love starts with the second child, there won’t be any left.
His wife is used to being completely suppressed by him, so what else can she do? Let’s just leave it at that.
Liu Haizhong turned on the radio and muttered: "This mission in this life is half completed. Go, go, don't disturb me listening to the radio. From today on, the policy document above, I You have to listen clearly and remember it firmly.”
——
The matter between Xie Jianye and Liu Haizhong should have been settled, but Deputy Director Li came to see Gao Zhendong again.
The reason for coming this time has nothing to do with the above two things. They are all trivial matters, the kind that are thrown away as soon as they are finished. Talking about them every day makes you look petty.
He came this time to have other serious matters.
"Zhendong, we received a notice from the ministry that your third factory is in a special situation and it is no longer appropriate to share a confidential room with the factory. We are going to build a separate confidential system for you. Some personnel and equipment , the ministry will provide it, and our factory will also provide some personnel. After all, it is our factory, and we have a good grasp of the internal situation. If you are not familiar with the situation in confidential work, there will be problems.”
Gao Zhendong was surprised that he didn't find this confidential room inconvenient. Although the factory area was not small, if something was urgent, it wouldn't take him more than a few minutes to get there by bike.
National Defense Working Committee: Nonsense, is that something convenient and inconvenient? Uh... Besides, it is indeed a bit inconvenient, and the leader is anxiously waiting.
But the ministry has brought it up, so it must make sense. It’s not a bad thing if you can run less steps.
"It's a good thing. The department is also very concerned about the work of our factory. All the factory leaders have worked hard to fight for our working conditions, haha."
Deputy Director Li shook his hand: " No, we know very well that this matter has nothing to do with us, you earned it yourself, haha, don’t put a hat on me. I came here just to discuss with you, the staff of this confidential room, you have No suggestions? ”
Um? What do you suggest about this matter? Looking at Lao Li's expression again, Gao Zhendong understood a little more.
This old boy came here for his nephew, his cheap student.
Gao Zhendong smiled: "This matter can be arranged by your factory. We have no objections."
Who can represent the factory here is Lao Li.
Old Li also smiled: "Well, what the factory wants is to select the best among the three branches. After all, the comrades in the branch are the most familiar with the situation. In this case, the factory will make a list. When the time comes, you and Lao Yan will check it out.”
Only then did he mention Factory Director Yan.
In fact, if he just arranged it directly and put Xiao Li on the list, Gao Zhendong would definitely not stop him.
However, he is a good person who has his own set of rules for doing things. In his opinion, since Xiao Li is called Teacher Gao Zhendong, he cannot directly arrange Xiao Li's use. Yes, whether it's good or bad, you have to say hello to Gao Zhendong first and discuss it.
Gao Zhendong nodded: "Okay, you arrange it."
After talking about this matter, Lao Li mentioned another matter.
"By the way, Zhendong, the crystal and furnace of 1761 are almost ready for mass production. Can we take it back for production?"
This "stove" does not refer to three points. The factory is already producing single crystal furnaces, but refers to the pressurized recrystallization furnace used for the production of mercury cadmium telluride.
Gao Zhendong smiled and said: "That thing needs to continue to be produced, but in general the output is not much and the thing is not big. It is not helpful for the factory to complete the annual production tasks."
Deputy Director Li has a lot to think about: "The output value is not high, but it is of great significance. And when it comes to the production of equipment, we are definitely better at it."
I, Lao Li, like it Is it that little production value? What I like is that this thing is special.
Gao Zhendong thought about it. If 1761 wants to produce this stove, with the personnel and equipment they have there, it must be done by hand. It is definitely not as good as the workers and masters of the No. 3 Factory plus the production equipment.
From this perspective, Deputy Director Li’s proposal does make some sense.
“Let’s do this, let’s take over the furnace, and leave the subsequent production of the crystals with them. Each family will share it, and we will have a share of it. At least we have to leave a flagship product for others. They are professional in the production and improvement of crystals. They have cooperated with us several times. In addition to honors and achievements, we also have something else to offer, and we don’t lack this.”
< br>Deputy Director Li gave a thumbs up: "Okay! Zhendong, you are good at everything. What's even better is that you have structure and grandeur!"
Wonderful man, quite a few people are praising this. In a sentence, you may habitually use the pre-modification "that's all you are good at", but Lao Li's choice of words is really impeccable. Lao Li would be satisfied if he could bring over the production of the pressurized recrystallization furnace. He also understood the principle of sharing the cake together.
After seeing off Lao Li, there is a call from the confidential room. Chief Engineer Gao, come here quickly. I need to talk if you have the chance.
Okay, it seems that it is necessary to have a confidential room in the third factory, Gao Zhendong thought while riding his bike.
When I picked up the phone, it was a stranger: "Hello, Mr. Gao, I am Tao Zhisheng from the Jianning Institute of Electromagnetics."
I don't know him, but the unit is clear, not just because His self-introduction was because the confidential room would naturally verify it.
For a moment, Gao Zhendong didn't remember that he had any interaction with the electromagnetic field. Even if it was electronic confrontation or something, he was still talking to the shipbuilding department.
The other person was very enthusiastic. After a few greetings, he talked about the serious matter of the phone call.
"Chief Engineer Gao, I am taking the liberty to call you this time because of an idea you proposed to the comrades in the artillery not long ago, about the artillery position reconnaissance radar."
Gao Zhendong Only then did he understand and said with a smile: "That's just my idea. You are the experts in radar."
"Mr. Gao is being humble. Your suggestion does have a good theoretical basis." Yes, the possibility of realization is very high, and the technical and tactical significance is also great. Just after that meeting, the artillery leadership immediately contacted us and asked us to carry out some preliminary research work. He also specifically said that if there were any questions. , I can talk to you. "The comrades of the Electromagnetic Institute are very humble.
Gao Zhendong, on the other hand, understands his own affairs. He actually doesn’t understand this stuff very well. He knows the concepts and can come up with ideas. However, other people are much better than him in terms of technical details.
"Haha, potter, let's talk first. I just think this thing is feasible in principle, so I can give you an idea. As for the profession, I don't understand it, so I may not be able to tell you anything."< br>
First lower the other party’s psychological expectations, which is to use all marketing methods.
The potter smiled and said: "In any case, as the initiator, Mr. Gao must still have something worth learning from us, and he can think of things that we can't think of for the time being."
He also feels that this On the other hand, Gao Zhendong probably can't offer any professional opinions, but maybe he has some flashes of ideas that he hasn't been able to fully express.
"As for the selection of the waveband, we don't have any problem. The wavelength should be smaller. The cannonballs are small, and the wavelength is small, so that they can be effectively detected and positioned accurately. However, we have done preliminary mathematical simulation calculations and found that the error is a bit large. I don't know how high it is. Do you have any advice on this? "Anyway, it's always right to ask.
Potter is still grateful for the popularization of DJS series transistor computers. In the past, it was difficult for them to apply for the right to use computers. At that time, this kind of similar simulation analysis alone was not as good as it is these days. What can be done within a short period of time is very delayed.
Now that they have their own computers, the entire process of pre-research, simulation, verification, and calculation has been greatly compressed, greatly improving research efficiency.
This simulation is incredible. The error is a bit large. Even the simulation error in the ideal state is so large. In actual use, the error will be even greater. It is simply unusable.
Hearing what he said, Gao Zhendong felt relieved. Hey, you should have told me earlier. I don’t understand radar, but I still know a little bit about mathematics.
Since it is a simulation, the radar performance issue can basically be put aside for now, and it is estimated that a certain fixed error can be directly substituted into the calculation.
Without the problem of radar, Gao Zhendong would not be sleepy. In his previous life plus this life, he also has the experience of studying and compiling "Principles of Automatic Control". In terms of algorithms, he thinks he is still better than the potters and others. In some ways it's just a little bit better.
"That's it, potter, can you tell me about your simulation process?"
The potter did not hesitate at all. The exact words the artillery leader said to him were, "There is no need to keep confidentiality." If you have any concerns, ask whatever you want, and Mr. Gao will provide you with whatever he wants to know."
“We first found an actual ballistic trajectory and weather data with ideal conditions, and then substituted the ideal performance and typical errors of the radar to simulate using radar to intercept the projectile’s point in the trajectory. The returned error data is used to perform inversion using algorithms starting from 2 points and continuing to multiple points to compare the error with the actual ballistic trajectory.”
The idea is very clear, and the amount of calculation is relatively large. Fortunately, I have a computer.
“Which algorithms did you use for simulation?”
After hearing Gao Zhendong’s words, the potter complained in his heart. Fortunately, he didn’t believe your nonsense. Why don’t you understand? Being able to ask this sentence at least means that you are a veteran in algorithms and simulation: "We have used parabolic approximation, least squares fitting, and Kalman filtering."
Gao Zhendong heard this and said: "Oh, you have tried the fast prediction algorithm and nonlinear filtering."
