Chapter 742 A New Subject
After a cordial and friendly exchange, Tang Lintian finally agreed to adjust the number of class hours and assessment methods of basic courses as soon as possible, and Chang Haonan also promised to allow two seniors to pass every year His research group participates in public practical projects.
When students who are included in this training method graduate, in addition to the normal degree certificate and graduation certificate, they will also receive a certificate of participation in the "Excellent Engineer Training Program".
Both parties have achieved a satisfactory result.
“Now that the matter is over, I won’t bother you any more.”
After receiving Chang Haonan's assurance, Tang Lintian put down his empty glass, stood up and prepared to leave.
As the host, the former naturally could not let the other party go alone, so he quickly got up to see him off.
While taking the elevator downstairs, perhaps to avoid being left in the cold, Tang Lintian asked casually:
“Professor Chang, I don’t know what research direction you plan to choose first after the Torch Laboratory is established. ?”
“Well...two levels.”
Chang Haonan thought seriously for a moment until the elevator reached the first floor and the two of them walked out before replying:
"The laboratory as a whole has just been established after all, so I'm afraid it won't be able to do any particularly difficult subjects, so I plan to find a few less difficult projects in the aviation system to practice my skills first, and also to enhance the understanding among the members of the research team.”
“As for myself, I plan to focus on the materials next. Of course, as mentioned in the defense in the morning, the study of inertial manifolds in dissipative partial differential equations, which naturally also includes the application of N-S equations, but the latter is research at the level of mathematical theory and relies more on inspiration, so it is very It’s hard to have a definite timetable.”
“Materials science? Our school doesn’t have much research foundation in this area...”
Tang Lintian is not from science and has no understanding of cutting-edge mathematical theories. Not much, so I decisively gave up delving into the next half sentence.
"Well, of course I know that."
Chang Haonan nodded:
"So, what I am planning to enter is a new direction, combining numerical methods with materials science research. "
Looking at Tang Lintian's slightly confused eyes, he had no choice but to give a further explanation:
"Simply put, it is to use physical modeling and numerical calculation methods to understand the characteristics and structure of materials. , components including processing technology for directional analysis and calculation. ”
"Compared with the traditional research method of materials science that is close to alchemy, once my idea is realized, there will be obvious advantages in predictability and regularity."
"Doesn't that mean that there will be opportunities in the field of materials science in the future? Maybe it’s like how we design aircraft, where the user gives a series of performance parameters, then carries out targeted design, and finally provides a customized process and processing plan?” Quite strong.
Besides, he has a background in computational fluid mechanics, so it is easy to make analogies to his own research field.
“That’s right, but the simulated objects are different.”
Chang Haonan smiled:
“Well, materials science mainly focuses on particle relationships at the microscopic level or multi-field composite relationships at the macroscopic level. The demand for computing power and algorithm design is different from computational fluid dynamics. "Exactly the same."
Tang Lintian also knew that even if he had reached the top in scientific research, otherwise he would not have turned to full-time administration, so he was very self-aware and did not discuss the technical details in depth, but talked about it. One turn:
"This...should be considered a new subject? At least I have never heard of it before."
"In fact, this research direction has existed for a long time, not to mention others. I myself completed a development project related to special steel the year before last, using the method just mentioned.”
What Chang Haonan was talking about was the time when he designed the bearing steel formula and process for the three major bearing groups.
To a certain extent, it can be regarded as an indirect cause of the concentrated decline of a large number of Japanese brands represented by NSK and NTN Group in the European market.
A large wave of whale (shark) losses (drops) has also revitalized many companies from China, South Korea, Eastern Europe and even Southeast Asia.
Looking at Tang Lintian, who was already a little dazed next to him, Chang Haonan paused for a moment and allowed the other party to relax a little before continuing:
"Including those who recently did the production acceptance of the heavy-duty die forging press. During the process, I also tried to use numerical methods to guide the research and development of the titanium-aluminum alloy forging process. Judging from the results, the overall efficiency was improved by about 40%. ”
"However, so far, research in this area is indeed relatively scattered and has not formed a complete discipline. If I were to say it, it may be called 'computational materials science'."
Two More than ten years later, the situation is different. In the late 1990s, materials science could not be regarded as a prominent science, and it was still a relatively weak part in China. But it is precisely because of this that the input-output ratio will be more beautiful——
In order to make up for the shortcomings in the field of materials, technical personnel are often forced to exert more effort in other parts such as design optimization. high level.
In this case, when material science in turn fills in the shortcomings, it will often have the effect of affecting the whole body.
As has been achieved previously in the field of bearing gear steels.
"Then, I wish Professor Chang success in his new research direction!"
For Tang Lintian, after successfully making his school one of the top C10 leagues in China After that, he really felt like he had lost his purpose in life.
But now, it seems that another golden opportunity has appeared in front of him.
Create a new discipline.
It is true that this kind of thing cannot be done by one person alone.
But there must be one person who can be the core.
"If you have any problems, the school will try its best to help you solve them!"
Before getting on the bus, Tang Lintian shook hands with Chang Haonan again.
In fact, considering that the latter is already considered a "half-step academician" and is about to take up the post of chief planner of the Aerospace Power Group, if we really count, the resources at his disposal are actually more than As the principal of Beijing Airlines, Tang Lintian only has more.
But no matter what, the attitude must be put here first.
Besides, no one would support too much, right?
......
After the doctoral defense was settled, Chang Haonan did not immediately start a new job, but planned to rest at home in Beijing for a while.
After all, the test flight process of Turbofan 10 is going well now. As for setting up the laboratory...
The candidates for several lecturers have been basically determined, but the next class of students will not be able to start contacting them until August or September at the earliest.
It’s okay if you recommend exempted students. If you are a student preparing for the postgraduate entrance examination, you won’t be able to let others come over to work at least before the initial examination.
There is no rush at this moment.
Moreover, for nearly five months from the Spring Festival holiday in February to now, he has been traveling almost non-stop in Jiangcheng and Beijing, occasionally taking time to listen to the returns from the Taihang project.
Really need to relax a little.
However, the idea is beautiful.
At Chang Haonan's current position, his time no longer belongs entirely to him.
Before enjoying a few days of relaxation, I received a call from Ding Gaoheng.
A lot of things happened in the more than half a month before and after his defense.
The most important thing is——
The fragment of the B2 bomber was carried back by Lao Wu among a pile of sample materials from the Azov Steel Plant.
