Chapter 232 The celebration party of the three gates! (2-in-1)
When Liu Hongbo received the task of "helping Chang Haonan complete the compilation of a finite element method course textbook" about a week later, he agreed with almost no psychological fluctuations.
I'm used to it.
Besides, now it’s just a matter of helping his fellow juniors. They have the same seniority, but the age gap is a little bigger, so it’s not embarrassing.
He was just very lucky that Du Yishan came out halfway and snatched Chang Haonan away from him——
If there hadn't been such a thing, now he would be a scapegoat for his own students.
Oh, he can’t even be considered his student, because Chang Haonan is still technically studying for an undergraduate degree.
In short, if that happens, he may not be able to continue to work in the education world.
As for what made Chang Haonan write a book, put his name on it and reach the top of his life...
Liu Hongbo never even thought about it in that direction.
It's not just a matter of academic ethics.
But before anyone does this kind of thing, he must weigh the other party's weight -
Look at the circle that Chang Haonan is in contact with now.
It can be said that there are scholars who talk and laugh, but there are no idle people in the contacts.
Even if this kind of person becomes his graduate student, it is absolutely impossible to be manipulated.
Don’t you see that even Du Yishan rarely interferes with Chang Haonan’s projects now...
The former has paved a lot of roads with his own influence.
If it were Liu Hongbo, he would have to write the words "morality and unworthy" on his forehead.
It will only embarrass both teachers and students.
So it’s better to be brothers.
He still has this bit of self-awareness.
"Huh..."
Liu Hongbo, who returned to the office, spread the two-page fax he got back from Tang Lintian on the table and let out a long sigh of relief.
Written on the paper is the outline and basic ideas that Chang Haonan determined for that textbook.
“Start with vectors?”
He read it over and over twice, but still felt that the content inside seemed a bit too lengthy.
At least the contents of the first three chapters should have been covered in the basic courses of the first and second year undergraduates, so there seems to be no need to repeat them here.
After thinking for a moment, Liu Hongbo picked up the two pieces of paper on the table, walked out of the office quickly, and came to his laboratory.
It was already the fifteenth day of the first lunar month. Although there were still a few days until the school officially registered and started, many students had already returned to school early.
"Teacher Liu."
The three graduate students who were busy in the laboratory saw the instructor who suddenly walked in. They said hello casually and continued their work.
As a relatively young professor, Liu Hongbo himself often appears in the laboratory, so the students are not surprised.
But the purpose of his coming today is quite special.
“I have a question to test you.”
Liu Hongbo came to the blackboard at the other end of the laboratory, picked up a piece of chalk from the side, and wrote a two on the blackboard. Dimension matrix ζ=[1,-1,-1,1].
When he turned around, he saw three confused expressions.
"Teacher Liu, this is..."
The three students who came back early to start experiments are all senior masters or doctoral students, and they are already a little unfamiliar with the exam format. .
What's more, Liu Hongbo has never played this trick in the past.
“Suppose in the plane stress analysis, the stress measured at a point in the non-primed coordinate system is the ζ on the blackboard. Now we ask you to establish its components in the primed coordinate system. You will How? ”
The three students looked at each other for a few seconds, but this kind of question obviously didn't stump them, and one of them quickly wrote the answer on the blackboard.
ζ'=PζP(T)
Where P=[cosθ, sinθ, -sinθ, cosθ].
“Very good.”
Liu Hongbo nodded with satisfaction:
"Then let's change to a slightly more complicated problem."
He erased the things on the blackboard and drew a beam fixed to the wall.
This is a beam with a bending stiffness of EI. The load on the unit length is P. The spring stiffness at the other end of the beam is k. Now it is necessary to use four finite difference nodes to establish the control equation of the beam response. .
This time, no one could give the results quickly.
In fact, from the eyes of the three students, Liu Hongbo knew that they should be very confused about this issue.
After a while, the boy who had just written the answer said with confusion:
"Teacher Liu, is there any connection... between these two questions?"
"They..."
At this time, Liu Hongbo suddenly realized that he himself could not give a systematic answer in words.
“Simply speaking, the first question can be seen as the theoretical basis for solving the second problem.”
"..."
This explanation is obviously unsatisfactory.
"Teacher, I remember you said in class before that the theoretical basis for airplanes to fly is only Newton's third law proposed in 1687, but it was not until 1903 that mankind created the first A plane..."
The other person's tone was obviously a little dissatisfied.
"You are right..."
Liu Hongbo stared at the blackboard for a few seconds, then patted the shoulders of the students next to him:
"It's okay, you can continue working."
After that, there were three inexplicable words. With eyes wide open, he strode out of the laboratory.
In fact, what Liu Hongbo proposed was just the simplest linear analysis problem in rigid body mechanics.
If these students are given enough time, they should not be unable to solve it.
But the reactions of the three of them just now showed that for an inexperienced person, the distance between basic mathematical knowledge and practical engineering applications is not as close as he had imagined before.
In other words, Chang Haonan’s design of the knowledge structure of the textbook is right.
The first three chapters are not useless parts.
The density of knowledge in college classes is often very staggering, and there is not much time for students to think and react slowly. If the teaching materials are relatively simple, it will easily lead to students getting stuck somewhere. Live, and then can no longer keep up with the class ideas.
So there is a saying——
In math class, I bent down to pick up a pen. When I raised my head again, it was as if I was listening to heavenly scriptures.
Perhaps because compared to other people who compile textbooks, Chang Haonan himself is still a student, so he grasps these pain points more accurately.
Liu Hongbo shook his head as he walked and said with emotion:
“MD, this is outrageous.” He was originally planning to continue to subcontract the basic content to his graduate students to write of.
But now I have changed my mind.
Obviously, Chang Haonan, a junior fellow student, can be embraced not only in the academic world, but also in the education world.
So he decided to write the book in person.
"Just think of it as a way to experience Professor Chang's educational thoughts in advance..."
Liu Hongbo told himself as he opened the office door.
In fact, Chang Haonan originally planned to take advantage of his time in Haojing to write out part of the framework before cooperating with Liu Hongbo.
This will make it easier for the other party to understand your overall ideas in this book, and save a lot of effort in later revisions.
But God is not as good as man, so he just wrote the beginning, and one night he received a call from Ding Gaoheng.
"Director Ding?"
"Xiao Chang, pack your personal belongings immediately and come back to the capital with me tomorrow morning."
"Go back to the capital?"
The words from the other party made Chang Haonan a little confused:
"But aren't the negotiations here not over yet?"
" Now the most important things have been basically decided, and the things in Beijing are much more important, and you must be present."
Ding Gaoheng did not explicitly state the purpose of his trip to Beijing on the phone, but listen. It was obviously very urgent to go up.
Therefore, Chang Haonan subconsciously thought that there were some technical problems that needed him:
"Okay, let me prepare. Also, can you tell me what kind of work it is? It's better for me to prepare in advance. "
Hearing this answer, Ding Gaoheng let out a hearty laugh:
"Why, can the call I made just be to assign you a task?"
< br>Chang Haonan rolled his eyes and said, isn’t it?
Of course he wouldn't say it out loud yet.
“Isn’t this a conditioned reflex? When I was celebrating the New Year at home at the beginning of last month, I answered a phone call around this time after dinner, and I was called to Haojing.”
"This time... it was an unexpected situation, an unexpected situation..."
Ding Gaoheng was somewhat embarrassed when talking about this matter. After all, it was he who recommended Chang Haonan as a technical expert to the negotiating delegation. consultant.
At the beginning, we only wanted to let the latter play a check-checking role. No one expected that after two rounds, it would actually open up a future for China's civil aviation industry.
At least the regional airliners built in the future will carry both Chinese and European certifications. As long as their technical level is excellent, they will not worry about lack of sales.
Brand effect is like this. Even if it is exactly the same thing, it will be more easily recognized if it has a xx standard brand.
As for the aviation industry, Europe and the United States are the first countries to develop, and naturally they have the most recognition.
From this perspective, Chang Haonan can be said to be the hero of the entire Chinese aviation industry this time.
“Don’t worry, it’s a good thing to call you this time. You’ll know after you come back to the capital with me tomorrow.”
Ding Gaoheng said comfortingly to the other end of the phone while thinking about what benefits he should use to compete with the National Science and Technology Commission for people.
Of course Chang Haonan doesn’t really have any objections:
“In that case, I will wait for the good things Director Ding will bring tomorrow!”
… …
The person responsible for taking Ding Gaoheng and Chang Haonan back from Haojing was a Boeing 737-300 of the 34th Air Division.
What surprised the latter was that their plane landed directly at the airport in the western suburbs of Beijing.
Since the opening of Terminal T0 of Beijing Capital International Airport in 1958, it no longer undertakes any civil aviation business and has become a specialized military airport.
Chang Haonan never did anything earth-shattering in his last life. Although he has done a lot of work after his rebirth, the time is still too short after all. In fact, he has not seen any big occasions, so last night After receiving that obviously unusual phone call, he actually thought about many possibilities.
However, judging from the scene of picking up the plane in front of him, the battle this time seemed to be much bigger than he expected.
Not to mention the common cars such as BJ2020 in the front and rear of the fleet in the distance, but parked in the middle are several black luxury cars with exquisite workmanship and square heads and square heads.
Even if Chang Haonan doesn't know much about cars, he still knows them.
Nissan Duke King V6.
It is considered the last generation of Nissan’s luxury car.
Of course, there are even Mercedes-Benz S600s in the army these days, but they will not appear here, but in the hands of some military companies.
And according to the course of history, there is not much time left before "no business is allowed". Many military companies have already begun the process of liquidation or divestiture.
In short, in this year, the specifications of the fleet composed of several Dukes and Kings are already quite good.
After getting off the plane, Chang Haonan followed Ding Gaoheng and got into a vehicle in the motorcade led by several staff members wearing casual suits.
"Director Ding, let's go..."
After getting in the car, Chang Haonan looked at the luxurious accessories inside the car with some restraint.
This is the first time in my two lives that I have received this kind of treatment, so I can’t blame him for not letting go.
Having already arrived here, Ding Gaoheng naturally had nothing to hide. After adjusting his clothes, he simply replied:
"Jingshan Front Street."
Chang Haonan was stunned.
This place name is quite unfamiliar to him who came back from more than 20 years ago.
Ding Gaoheng next to him also saw that he failed to understand, so he filled in another explanation:
"It's the three gates."
"Hiss..."
Chang Haonan knew now——
It is early March 1997, and he was familiar with it in his previous life The Bayi Building at No. 7 Fuxing Road has just broken ground at this time, so Junwei's office is still located at the third door.
Thinking of this, Chang Haonan felt his heart beat a few times unsatisfactorily.
The highest-level meeting he had attended before was the internal commendation meeting of the Aerodynamics Research and Development Center. Now he had a big event in one go. To say he was not excited at all would be a lie.
Just kidding, how many people have never even entered the county Wei in their lives.
Besides, this time we were picked up by a motorcade.
“So there is a meeting?”
Ding Gaoheng nodded:
"Yes, a small-scale commendation and celebration. Of course, the semi-public statement within the army is to celebrate the official installation of the J-8C aircraft. You will know the more specific situation when you arrive."
Chang Hao Nan did not continue to speak, but turned to look out the car window at the roadside buildings passing by quickly, trying to calm down his somewhat fluctuating emotions.
The commissioning of just one type of aircraft will not lead to a celebration party at the three-seat gate, even if the J-10 is built.
And it has only been three months since the small-scale trial installation of the 00th batch. According to the training frequency of the aviation force in the 1990s, the troops may not even be able to fully understand the functions of the aircraft, nor can they fully understand the functions of the aircraft. It should be officially put into service soon.
But since this statement is semi-public, it should not be a complete fabrication. It must also be related to the J-8C model.
In other words, in the three months since he left Shengjing, something terrible might have happened!
