On the other side, after all the data on hand was handed over and Li Xiang's matters were dealt with, Chen Nian returned to his regular study life.
For several days in a row, he went to the library to study as usual after attending small classes, but he never met Li Xiang.
I finally met him in the restaurant and found out that this guy was busy receiving confidentiality training.
He was probably taught by the same teacher as himself.
Good guy, this time he has really become a full-time employee - he is already living a salary-earning life before he graduates.
Li Xiang seems to be quite satisfied with this arrangement. After all, it doesn't delay his studies and allows him to indulge in bragging.
The only trouble was that in order to boast like that, his professional knowledge had to be improved as soon as possible.
Therefore, he strongly asked Chen Nian to take time to give him extra lessons, saying that his family would pay him double the market price.
This request was naturally rejected by Chen Nian - he couldn't arrange his own time, so how could he still spend it on him.
However, looking at Li Xiang's slightly disappointed expression, he still proposed an alternative.
"Otherwise, I think you already have a good foundation and are smart. In fact, you don't need extra tutoring."
"However, you may need some guidance in key directions, and I can help you with this."
"To put it simply...can I draw a key point for you?"
According to Chen Nian's considerations, one-on-one tutoring is impossible, as it would waste too much time.
But if I just focus on helping Li Xiang find a more efficient and accurate learning method, it won't take up too much of my energy.
Li Xiang was overjoyed when he heard Chen Nian's words.
"Chen Nian, you are my brother, so it's up to you!"
In fact, as Chen Nian said, his foundation is very solid. What he lacks the most is guidance at key points--and university teachers, especially some teachers from Western Polytechnic University, say To be honest, the bureaucracy is quite heavy and it is difficult for students like him to get close to him.
Therefore, there is no way to make up for this.
But now that Chen Nian is here, there is no need to worry.
You know, he is the only student who can skip classes at will and is praised by most teachers.
Coupled with the fact that he goes to the library every day and is often used as the standard answer for exams, I believe he is definitely right.
Thinking of this, Li Xiang added:
"In the future, if I have any questions that I don't understand, just ask them for me. As long as I get through them, I can figure them out myself!"
"Okay, let's work hard together!"
Chen Nian smiled and replied.
Then, as soon as he swallowed a mouthful of rice, Li Xiang sat over mysteriously.
"Hey, Chen Nian----no, Brother Chen, I just have a question, can you help me with my advice?"
"What's the problem?"
Chen Niannian asked without raising his head.
He was concentrating on fighting with the piece of chicken on the plate that he kept biting, and he was so anxious that he could not wait to swallow it in one bite.
"About the central lifting body."
"Central lifting body? Why did you suddenly think of this subject?"
Chen Nian asked doubtfully.
You know, the aerodynamics courses they take now are relatively basic, mainly focusing on the theoretical part, and they haven't even learned about airfoils yet.
The concept of central lifting body layout was only created in the third-generation aircraft era. It is relatively new compared to other content they learn, and is not mentioned in general classes.
It was a bit strange for Li Xiang to suddenly bring up such a topic.
Hearing Chen Nian's question, Li Xiang smiled sheepishly and replied:
"I just thought of it by chance... I wasn't discussing it with the spy before. Some of the things he said made sense to me - ah, I can't tell you too much."
"In short, I have read some information recently and feel that the layout of the central lifting body is actually quite promising. On the premise that the engine performance cannot be improved, using the central lifting body layout can greatly improve the maneuverability."
"However, there are many issues that I don't know about when it comes to designing a central lifting body, so I would like to ask you where we should start."
"Don't worry, this is just my personal interest, I don't have any other ideas."
After hearing what Li Xiang said, Chen Nian felt relieved.
Have other ideas?
You dare.
We are all comrades within the system. If you make a mistake, it will be over if you are not caught when the time comes...
However, Chen Nian was somewhat familiar with the subject of the central lifting body.
Even without the help of the system, in his previous life, like Li Xiang, he had looked up some information out of interest.
So, after thinking for a moment, he said:
"If you want to study topics related to the central lifting body, you must first understand what parameterization is. Nowadays, shape parameters are mainly realized through CAD methods. For example, NURBS curves are very typical."
"Of course, there are also those using the quadratic curve method."
"You have to understand these things first before you can truly understand the application method of airframe design. Only then can you think about how to design the central lifting body."
"Because the aerodynamic optimization involved in the central lifting body is more complicated than the conventional layout, there is much more to learn..."
After listening to Chen Nian's words, Li Xiang nodded solemnly.
"I understand. I'm going to look for some cases to take a look at first. Thank you Chen Nian, I feel like I have some direction after talking with you, so I won't be looking around like a headless fly like before."
"Hi, it's okay."
Chen Nian waved his hand, swallowed the rest of the meal in three gulps, and then turned around and went to the library.
But this time, Li Xiang also followed.
The two of them were doing their own thing quietly. Chen Nian was still learning the basics of materials science, while Li Xiang had already started to follow the path that Chen Nian had pointed out to him before, to see cases related to parametric design.
It wasn't until after ten o'clock in the evening that Chen Nian got up and planned to leave. He called Li Xiang, but the latter waved his hand and said:
"Chen Nian, you go first today. I just saw the key point. I will watch it for another half an hour..."
Seeing the obsessed look on Li Xiang's face, Chen Nian no longer disturbed him, but said goodbye and walked out of the library.
On the way to his residence, Chen Nian opened the system interface. Judging from the display on the interface, his current number of source points has accumulated to 0.46 points.
One step closer to the goal...
Chen Nian smiled with satisfaction and was about to turn off the interface, but at this moment, the number "0.46" suddenly jumped and instantly became 0.47!
What's going on? Does walking count as learning?
Under normal circumstances, the growth of the source point will end when the learning action is completed. Unless you have been thinking and have some new insights, occasionally there will be a delay in settlement.
But he was very sure that he was definitely not thinking about anything just now!
what's going on?
Wait... could it be Li Xiang?
Could it be that his study was also counted on him?
Chen Nian did not hesitate and turned around and returned to the library. As soon as Li Xiang saw Chen Nian in his seat, he stood up excitedly.
"Hey, Chen Nian, come here quickly. I just had a new idea and was about to ask you, but you came back..."
"What new idea?"
Chen Nian asked impatiently.
"It's the problem of parametric design you mentioned. I saw a case where quadratic curve was used to solve the optimization of lifting body layout, and then I felt that the quadratic curve was defective."
"The process of finding the coordinates of the end tangent intersection of a quadratic curve is too troublesome. Curves with discontinuous second-order derivatives must be processed in segments."
"I'm wondering if it would be simpler if we use the agent model method to solve it."
"I tried it just now, and it seems to work!"
"Chen Nian, come and take a look!"
Chen Nian took the draft paper from him and understood it completely at a glance.
In fact, this is not a big breakthrough. At best, it just optimizes part of the modeling algorithm, and it is not even enough to write a paper.
However, if we continue to diverge from this method, in the future, when computer technology is fully developed and new tools such as genetic algorithms and machine learning are introduced, the potential of this small optimization can be unleashed.
Is this why the system issues source points?
Chen Nian's heart moved and he vaguely realized something.
If this is the case, it most likely means that my previous understanding of the system rules was incomplete.
The so-called source point does not come from the learning process, but from "knowledge increment".
As long as this "increment" is caused by yourself, you can get rewards.
Doesn’t that mean that my true direction is to be a top-level designer?
The correct working method is not to parse out all modules, but to focus on inspiring and breakthrough technologies to achieve self-circulation of the source...
Good guy, no wonder I always feel that the source point is not enough, and the relationship is about not finding the right method!
Fortunately, both the engine and the body design are inspiring, and sooner or later new results will be brought back to the source, otherwise it would be a big loss...
