Chapter 240 Waiting
The relevant departments have issued a special statement that the country is committed to promoting projects that benefit the people. Previously, these projects were pilot cities. The country plans to invest hundreds of billions of yuan to supervise the construction of a series of projects that benefit the people. They will speed up the promotion and popularize these policies that benefit the people to thousands of households and the whole country, which will surely make the people of the country feel the warmth of the country.
Since it is gradually becoming popular, they can still wait and see. They have to give it some time as arranged by the higher-ups.
After the deep mining project of the poor mine was successfully launched, Cheng Huanan immediately rushed back to Shangjing. The first thing he did was to go straight to Wu Tong's office.
"Teacher, you're back? Did everything go smoothly along the way? You've worked hard!" Wu Tong quickly stood up from behind his desk, welcomed Mr. Cheng, who was still dusty from the journey, to sit down in the rest area, and handed him a cup of warm water.
It's not that there is no tea in her office. Coffee and tea are all specially provided and are placed there casually. The standard of care she receives in life can be said to be almost top-notch.
It is not suitable for people who travel long distances to drink tea.
"It's okay. I'm still strong. I won't get tired from running back and forth!" Cheng Huanan drank some water slowly and waved to Wu Tong, telling her not to worry.
Wu Tong has achieved such great results, and they just ran errands and supervised the installation of the production line on site. They don't have to be exposed to the wind and sun, so it's not hard at all.
"Everything went smoothly. Several projects were successfully completed. The metal powder extracted by the Xinjiang Extraction Center is of very pure quality and can be directly processed. Wu Tong, you have really made a great contribution!" Cheng Huanan couldn't help but get excited when talking about this. The older generation like them would like to see nothing more than seeing the country they have fought for all their lives becoming increasingly stronger.
Since they started working, they have been striving for the rise of China. Just like Mr. Zhou's ambition when he was young to study for the rise of China, this belief has always been with them, becoming their unchanging original intention and firmly engraved in them.
"I have only made some achievements. What I really want to thank is the courage and determination to promote and trust me!"
"They are all important!" Cheng Huanan concluded, and then switched to the next topic, which was also the reason why he rushed to Wu Tong's office as soon as he came back: "You sent me the document. I read it in my free time. It's really wonderful. I have a few questions that I don't quite understand. Can you explain it to the teacher!"
After Cheng Huanan took a breath, he quickly took out his notebook and a pile of printed documents from his briefcase. As an older man, he was more used to paper documents. Of course, he was not a stubborn person who was stubborn and could not adapt. He would still use computers and other technological products. It was just his reading habits. He did not make directional changes when conditions allowed.
After printing the stack of documents in the confidential room, he never left his briefcase day or night to ensure that nothing went wrong.
"Wu Tong, look, this little bit... and this little bit..." Cheng Huanan opened the document, holding a pen, and asked about the difficult points that he had circled one by one.
Wu Tong took a look and the research at that time immediately appeared in her mind. Wu Tong took a pen and paper and began to tell Cheng Huanan about it. The old and the young discussed for two hours. Cheng Huanan completely understood this material optimization plan.
"I won't say much to thank you, teacher. You are a co-developer of this material, so don't refuse it. This is what you deserve!" Cheng Huanan promised firmly, and then stood up: "I will go to the laboratory to supervise and implement the experiment. You wait for my good news!"
After saying that, Cheng Huanan left in a hurry, without giving Wu Tong any chance to speak.
The best he could achieve with this material was just the top domestic level, but Wu Tong pushed it to a level beyond the world's advanced level. Such optimization is equivalent to an innovation in research and development. Giving Wu Tong a co-researcher is already a great honor for him.
Wu Tong laughed. Well, she felt bad for the teacher's kindness. Fortunately, she did not skimp when helping the teacher to make the optimization plan. It was a real optimization, and she still made a contribution, not a white-collar work.
After seeing Cheng Huanan off, Wu Tong returned to his desk and continued with the deduction at hand.
Navier-Stokes equations, the equations of motion describing the conservation of momentum for viscous incompressible fluids, are referred to as NS equations.
The equation of motion for viscous fluids was first proposed by Navier in 1827, which only considered the flow of incompressible fluids. Poisson proposed the equation of motion for compressible fluids in 1831. Saint-Venant and Stokes independently proposed the form in which the viscosity coefficient is a constant in 1845, both of which are called the Navier-Stokes equations.
The existence of smooth solutions to the NS equations in three-dimensional space was set as one of the seven Millennium Prize problems by the Clay Mathematics Institute in the United States.
It is never a simple question. Wu Tong listed various conditions one by one.
The fluid is continuous, emphasizing that it contains no internal voids, for example, dissolved gas bubbles, and it does not contain agglomerates of mist particles. Another necessary assumption is that all the fields involved are all differentiable, such as pressure, velocity, temperature, etc.
The NS equations are derived from the basic principles of conservation of mass, momentum, and energy, for which it is sometimes necessary to consider a finite arbitrary volume, called a control volume, to which these principles are easily applied.
Deeply exploring the mysterious field of pure numbers, Wu Tong's mind is free and unfettered, and the joy of letting his imagination run wild makes people deeply addicted. A constantly changing pen, a pile of draft paper prepared in advance, and a quiet space without interruption are enough for Wu Tong's needs.
Having been involved in this field for a long time, she has many ideas about the NS equation. Now these ideas have been transformed into deduction directions, and Wu Tong has selected the best direction to move forward, which will gradually promote Wu Tong's progress in this equation. About the continuity of fields and fluids...
Line after line of deduction formulas are presented in Wu Tong's writing without any rush. Wu Tong's mentality is calm and peaceful. He builds a solid foundation bit by bit and moves forward slowly. There will always be a time when he will reach the end.
The road to success is always a long one, and only by being calm can you go further.
To a certain extent, Wu Tong would not insist on a certain level. If she could not break through this point, it could only be said that her accumulation was not enough, and it was not something she could figure out by just dwelling on it for a while.
Therefore, at this time, Wu Tong is more willing to change his mindset, study the contents of other sections, and delve into the literature that he has never come across in his current study, and continue to expand his knowledge. By analogy, or by continuing to learn, he will naturally find a way to solve the problem, extending the route forward.
