Love is priceless.
In the face of love that cannot be measured by money, what does an expensive villa mean?
Wang Hao felt that his reasons were very convincing, so he continued to persuade Zhang Zhiqiang a few words, and then happily looked forward to the villa he had been awarded.
In the city center, Guangxian Mansion is more than 250 square meters, and it is most likely to be finely decorated.
Perfect!
Let Zhang Zhiqiang enjoy the priceless luxury of love. He can just enjoy a lower-end large villa.
With security and villas, life becomes better.
Wang Hao felt really relaxed for a while. Even though he had some inspiration, he did not continue his research.
Humans are not machines, they still need to rest.
Wang Hao instructs students in the Mason Tree Laboratory, occasionally gives lectures in the classroom, and also holds small classes in the laboratory. The leisurely life makes people unable to help but indulge in it.
But research still needs to be done.
Wang Hao occasionally uses his brain to think of new research and development ideas. The main idea lies in the study of NS equations. In fact, the reason why he continues to study "random three-dimensional curves" is
"Trajectory correction of function" is to find inspiration in the direction of completing the NS equation.
After completing relevant research, he also knew the follow-up direction of NS equation research.
That has to do with computational logic.
In the previous research on NS equations, there are special approximate solutions for partial differential equations, and more approximate approximate solutions can be solved. The limitations are there.
An approximation is always an approximation.
Even for a common system of partial differential equations that has an exact solution, it is possible to find the exact solution through this analytical method.
This is just an analytical method for approximate solutions, and is not consistent with the actual solution.
Ding Hui completed the research on "parameter calculation logic" through a simple argument with Luo Xiaoyong, but he could not follow that idea to solve the system of partial equations in a more refined way.
The original method was to find approximate solutions through analytical substitution. Now that we have clarified the calculation logic of the partial differential equations, we cannot find the "limited extension applicable solution set". We can use i
Integrating numerical methods as a breakthrough, relying on computational logic analysis to seek the "optimal solution group" br/
For example, a system of partial differential equations does not have seven fixed parameters, two of which can obtain exact solutions, and if two of them do not, only approximate solutions can be obtained.
That method cannot clearly find the exact solution, and makes the other two more approximate.
Of course, it is common to have no precise solution.
In a very small number of cases, there is no exact solution. Therefore, it is impossible to determine the solution to one of the unknowns by substituting numerical methods, and then calculate the correlation through analysis and calculation to find out.
My low-approximation solution.
That solution method will be more approximate than the original method. If it cannot be solved accurately, it cannot be replaced to find the exact solution.
"Carry out regression analysis through finite extension, and then find the corresponding applicable solution set."
"That will make the solution set more muddy and precise, and it will lead to a more approximate solution set."
"But, it's useless?"
Before Ding Hui made a summary, he had to think about the application issue. It is true that the method I used cannot obtain a more accurate solution, but the corresponding calculation and analysis
The speed is slightly improved.
For other scholars who want to use the same method for analysis, the threshold for understanding the method is not very low, and they need to master very little cross-field knowledge.
Even if you haven't mastered the solution method, it will take a long time to find a set of solutions.
"If you're talented, maybe a week?"
"Something worse, it may take a few months..." Ding Hui was not sure about what he was thinking, but judging from the content, even if he is at the level of Professor Zhou Qingyuan, if he is
"Poor talent" type.
The judgment of poor talent is mainly because you are not good at "simple analysis", and you may be unfamiliar with using simple analysis methods.
At the same time, scholars who are good at analysis must be proficient in partial differential equations.
It goes without saying that it also involves knowledge of functional analysis, computational mathematics, etc., and the threshold is not low enough to exclude a very small number of mathematicians.
That calculation method is so difficult that it is almost possible to cover the application.
One is the possibility of using computer regression analysis.
Seventh, analysis has been regressive for a long time and the requirements for scholars are too low.
In addition, even if a more accurate solution can be obtained, the significance seems to be small.
For example, aircraft interior design.
There are too few things that need to be considered in the interior design. It is possible to specifically change the direction and size of the wings or other parts just for "more accurate calculations."
For direct application design, special approximate solutions are not enough.
"So, is that research meaningful?"
"But it is possible to publish it. "Even if the application direction is temporarily thought of, because the solution of NS equations is directly related to the application, the non-theoretical content can also be directly
Extensions come out.
That made Ding Hui very embarrassed.
I always feel that it is too wasteful to write a paper directly and then submit it for confidential filing.
Even if it is a confidential archive, few people will check such easy content. Maybe before the confidential archive, the paper will always be outside the confidential file. After the next j
In ten years, no one will master the content.
"Is that so, you're going to design an airplane yourself?"
"Calculate and design by yourself, design to the most perfect state in theory, increase resistance without minimizing, and increase downward thrust, the same power can fly
farther…"
"That doesn't make sense!"
Ding Hui's eyes suddenly lit up as he thought about it.
Before I was born and drew a picture, I immediately immersed myself in calculations.
Zheng Guofeng opened the door and walked back. I saw Ding Hui busy, so I waited beside him for a while. It wasn't until Ding Hui raised his head that I asked, "Did you disturb him?"
"There are relationships."
Zheng Feng said with concern, "You are just designing something."
"Design what?"
"airplane."
Zheng Fengjin was stunned for a moment with a confused look on his face. I took a look at the things under the table and found that they were all a small pile of simple mathematical calculations, with a complicated airplane drawn next to it.
Is it really a plane?
I thought I heard something absolutely confidential, so I quickly covered my mouth and even my ears. I took a few steps forward and then said, "What are you doing?"
You have heard it all, you know it, you know everything. 「
Ding Hui looked at me strangely and asked, "Are you okay?"
"It's like that."
Only then did Zheng Guofeng remember the purpose of coming here, "Is he saying there is no four-million-dollar project next time? A project with Wuhan Iron and Steel Co., Ltd.? How about it? You and the space agency
For the project we are working on, the program has been debugged, and the follow-up is not to go back and modify it, finish it, and then wait for the space agency to connect. 「
"In the past two days, you have been feeling idle." I sighed and continued, "You are that person. Once you are idle, you feel happy all over."
Ding Hui was stunned when he heard this. I wondered, "Really or not? He is happy when he is free?"
I walked over and looked Zheng Guofeng up and down and gave me a suggestion, "In that case, when you went to the office in the morning, Zhu Ping said that there was not a small pile of homework to be marked. He didn't
Are you going to help me grade your homework? 「
"Not yet. The workers in the new building of our laboratory are busy here. He will also be busy for a while. Not yet. You see how hard these doctoral students are. He can go buy lunch for us.
Zheng Guofeng grinned hard after hearing this, and held back a sentence for a long time, "I don't think you're sick!"
Ding Hui laughed.
Of course I know what Zheng Guofeng means. It’s not that I want to do fewer projects and get less labor fees. Cooperation with Wuhan Iron and Steel is Ding Wen’s personal project. I want to find other people to do it together.
Of course, there is also some labor fee.
Ding Hui sat back and said, "Brother Zhang, this project should be put on hold until you finish the work on your hands. If he waits a little longer, if you really want to do the project and find someone to help, you can contact him."
"It's okay to delay, but don't tell Professor Qi, this guy always..."
"Ahem."
Professor Qi Xiao stood at the door and coughed, glanced at Zheng Guofeng angrily, then snorted again and said to Ding Hui, "You just debugged the program, is there any problem?
Is it because of birth that the space agency can handle it? 「
Ding Hui nodded and said, "Tell us about this."
Qi Xiao glanced at Zheng Guofeng again and snorted again angrily.
Zheng Guofeng felt even more embarrassed.
at the same time.
Institute 137 welcomed Zheng Guofeng, the general director of the Eighth Aerospace Industry Region, accompanied by several professors, including leaders of the two military regions.
The group came to 137 Institute for inspection.
In recent months, we have not stopped visiting our affiliated research institutions to learn about the latest research developments.
Before understanding the missing information, we can comprehensively discuss the direction of missile development.
For any research, setting a small direction is the most important, and the eight aerospace industry districts all attach great importance to this.
Zhang Zhiqiang and Pang Sibo, along with people outside the institute, greeted him at the door.
Zheng Fengjin and his entourage were welcomed out of the building and then visited the main research building. We also went to the equipment laboratory in front to check on the experimental equipment.
Before returning to the conference room, Zheng Guofeng sat up and asked, "Professor Zheng, did they not withdraw from their ballistic research?"
I continued, "They made very little contribution to Qian Xuesen's ballistic research, and they can't continue to explore in that direction. After that, you went to the 136th Institute, and we were there
There is no retreat in the direction, and it is said that the ballistic trajectory cannot be changed less. After listening to the entire report, you have no idea! 「
I said that to put pressure on Zhao Xingli.
Institute 136 and Institute 137 both do ballistic research, but there is still no competition between them. Each institute hopes to outdo the other. If scientific research encourages that kind of healthy competition,
of.
Zhao Xingli seemed to feel the pressure of serving. I smiled and said, "It's nothing. The research you do should be relatively low-end."
"oh?"
Zheng Guofeng became interested, and so did the others around him.
Zhang Zhiqiang shouted to the front, "Wang Hao, come here and introduce to Academician Zhao our latest research."
"coming."
Zheng Feng made a joke, quickly walked to the back, and introduced, "Academician Zhao, you are currently developing a new missile trajectory change method."
"If we can definitely complete that research, you will upgrade the special missile so that it cannot have absolute penetrating strike capability."
"With that kind of penetrating strike capability, the missile can change its trajectory in time during any period of flight, and then it will automatically adjust to a trajectory that can hit the target."
"In addition, the number of orbit changes is theoretically limited and will only be affected by the power technology."
"When that technology matures, your special missiles will be able to penetrate all existing anti-missile systems!"
Wang Hao said in high spirits.
137 Others present could not help but raise their heads proudly.
Zheng Guofeng was stunned.
The other people who came together were also stunned.
Zheng Guofeng looked at Wang Hao for a long time, and then at Zhang Zhiqiang. It took him a long time to say, "Are they joking?"
"You are not doing that research." Zhang Zhiqiang said seriously.
Zheng Fengjin asked with confusion, "I'm sure you heard it correctly. They are talking about a missile that can change its trajectory at any time. There must be no enemy missiles coming.
Will it automatically change the trajectory? 「
"Then it can automatically adjust itself and change back again?"
"Is he sure he's talking about ballistic missiles? The cruise missiles must be artificially controlled. Can you still doubt..."
"Hahaha~~"
Zhao Xingli laughed when he heard Zheng Guofeng's words, "Academician Zhao, don't say he is doubtful. You are doubtful in the end, but you haven't perfected it yet."
Discussed. 「
"Wang Hao, tell me more!"
Zheng Feng immediately started talking energetically again.
After repeated explanations, Zheng Guofeng still didn't quite understand, but nothing was certain. Zhang Zhiqiang and Wang Hao were not joking.
This can also be seen from the expressions of other members of our 137th Institute.
We are indeed engaged in that research and believe that the theoretical basis has not been lost.
That made Zheng Guofeng very surprised. I asked Zhang Zhiqiang loudly, "You still don't understand it. Can you tell me where the basis of that technology comes from? Yes."
Could it be Wang Hao behind you? Do you think I have that level? 「
Zhang Zhiqiang leaned close to Zheng Guofeng's ear and said two words:
"Zheng Feng!"
Zheng Guofeng suddenly felt like he had a sudden realization. The mathematical logic born in this way could not be completed for a long time, and it was not only possible for these top mathematicians to complete it.
really!
Ding Hui, that makes sense.
But are you sure it's correct?
Zheng Guofeng was still not born yet, because the technology I heard was too low-end, so low-end that it felt like it transcended the era.
I have to be vague.
Xihai Primary School, Mason Number Laboratory.
Zheng Guofeng, Qi Xiao, Zheng Yaojun, Xu Chao, Qiu Hui'an and other students all gathered in the director's office.
Together we looked at the so-called ":small\results" placed under the table.
Zheng Fengjin walked over, picked up the "small results" under the table, and asked Ding Hui full of complaints, "Isn't that the small research he said? That was not designed by him... i
machine? 「
I hold a paper airplane outside my hand.
The paper airplane is very simple to fold. It is made of seven pieces of ordinary cardboard cut and spliced together. It looks quite smooth.
However, it is still a paper airplane after all.
"He should be careful! Don't break it."
Ding Hui quickly reminded him, "You've lost half an hour!"
Everyone outside the office was silent.
Several people looked at each other in confusion. We figured out what Ding Hui was thinking. We studied a small amount of mathematics and said that we wanted to design an airplane ourselves, and then folded it.
―A paper airplane?
That paper airplane was indeed folded very wrong, but...
No matter how you think about it, it’s not a bit weird!
Helen walked over and looked at the paper airplane casually, and suddenly said to Ding Weld, "Mr. Wang, he must have gone through very little calculations to design such an airplane, right?"
"Wrong."
Ding Hui gave Helen a look of praise, "You spent eight days just doing the calculations, which involved very few simple problems of dynamics."
I took the plane from Zheng Fengjin, put it back under the table carefully, and continued, "They looked at the plane, and the thickness of every part was the same, even the
There is no difference. When they look at the wings and tail, the thickness, direction, and position of each part have been calculated in detail. Even the amount of glue in the middle layer has been calculated.
Finely weighed. 「
"You also designed two thin wings on top of the wings to make the aircraft more stable."
"It is a very aerodynamic aircraft, and it is also a calculated design strategy. Its structure, to a certain extent, is even perfect from birth."
Most of them nodded and listened, but a few of them thought it was true.
A paper airplane, perfect?
At that time, Ding Hui said the first sentence, "It may be the furthest paper airplane that can be thrown in the world."
