After dinner, Ji Yu accompanied Song Jining back to the laboratory.Song Jining showed no defense against Ji Yu, and explained his research to him in detail.

"Catastrophe theory" is a theory involving a wide range. Fortunately, Song Jining is self-aware and only studies the field of mechanical engineering.

He has a solid foundation in science and engineering, and with Ji Zhuan's long-term guidance, his theory and knowledge have unknowingly surpassed this era. Even without Ji Zhuan's guidance, he still achieved good research results.

For example, the variable caused by friction in the operation of the machine, the sudden change of the vibration state of the rotor, etc.

"When the heat energy accumulated by the brake friction reaches 1.2pr value, the surface material of the two brake shoes is melted to form a degradation energy of 0.25f, which is a necessary condition for a sudden change in friction. For this reason, I have tried a total of 5 sets of data... ..."

Song Jining introduced his research to Ji Yu enthusiastically, just like when Ji Yu talked about professional knowledge with him in the past, he was eloquent and couldn't stop talking.

"...the more experiments you do, the more you understand. I think we can find out how to reduce the wear and tear of construction machinery..."

Standing beside Song Jining, Ji Yu patiently listened to his long, complicated and boring introductions of various data, without feeling bored at all.

Senior brother Jian Peng came in to take a look when he was about to get off work. Seeing that the two showed no sign of stopping at all, he couldn't help shaking his head: "Why are these two exactly the same!"

In the past, I only thought that Ji Yu was a nerd, but I didn't expect Song Jining to be a nerd in private. No wonder they have such a good relationship.

The lights in other laboratories were dimmed one by one, only Song Jining's laboratory was still on.

After seeing Song Jining's various experiments, Ji Yu wanted to help him, but was rejected.

"This is my own research, I want to do it myself, completely by myself." Song Jining: "Even if the research becomes more and more difficult in the future, I want to try it myself."

Song Jining, who was speaking, had bright eyes and exuded a strong yearning: "I feel more excited than fighting, starting a company, or making money when I get a sense of accomplishment from overcoming a difficult problem!"

Ji Yu could understand his feelings, and he said with a gentle smile: "If I just give you the necessary professional knowledge, it shouldn't be considered a help!"

In the next half month, in addition to reviewing his homework, Ji Yu also used his evening time to give Song Jining his knowledge of "Catastrophe Theory", and explained to him the contents of those professional books that Song Jining did not understand.

Half a month passed so quickly, and Song Jining made another major breakthrough in his research. He studied the data of metal fracture and damage during the cutting process, and wrote about the improvement direction of mechanical cutting and the idea of ​​precision cutting of metal.

Of course, it is just a conjecture. As for whether it can be realized, it depends on how many people accept his thesis and are willing to conduct research on it.

This is not something that a mere student, Song Jining, can interfere with.

"There will definitely be." After reading Song Jining's thesis, Ji Yu said with a very firm tone: "This is the direction of the future development of machinery. After ten years, people will definitely find out how correct this thesis is."

Song Jining's self-confidence was bursting with praise. This is not the level of praise for good test scores, it is a child's praise.He felt that now was a compliment to a man.

Although it is too exaggerated.

"Actually, I was worried that I would not be able to publish it officially. A senior brother's paper was returned." Song Jining said: "But since Yuanyuan agreed, I have confidence."

By the end of the final exam, Song Jining's research and thesis were coming to an end, and Ji Chen was going back to the Air Guidance Institute.

Although the Chinese New Year is approaching, but because it is a rare winter vacation, the Air Force Guidance Institute still has to seize the time for training.

Song Jining reluctantly sent Ji Rafter away, and quickly completed the dissertation. After strict review by Professor Jiang, he personally recommended it to an authoritative research journal.

The school is on vacation, Song Jining goes home, because Ji Yu can't come back, Li Shulan misses her son, and specially invites Song Jining, mother and son, to come to their home for the New Year, and ask about Ji Yu's current situation by the way.

Although Ji Chen also called to explain his whereabouts, but if he didn't ask in person, Ji's family was always worried.In their eyes, Ji Yu is always that soft child who is easy to be bullied.

Song Jining celebrated the New Year at Ji's house, except that there was no Ji rafter, it was the same as before, and he didn't feel uncomfortable at Ji's house.

The Ji and Song families have always been very close, and now they are working together to run a factory for their son. The relationship has long been good, just like a family.To Song Jining and Ji Yu, the two adults are their parents, and to the two adults, they are also their children.

So Song Jining did not take less red envelopes.

Although he has long been an adult, many people still give him red envelopes, including his executives.Two copies, one for quarter rafters.

Song Jining didn't have to keep his own, but Yuanyuan had to accept, so he collected a lot and deposited it all in the account shared by the two of them.

I saw my friends shortly after the Spring Festival. As the direct seller of Jisong Electric, they have expanded their business a lot, and they even came to give Song Jining a big red envelope as a thank you.

"This is for Yuanyuan, not for you, you refuse to be tall!"

Song Jining opened the red envelope afterwards and found that it was all checks with more than six figures.

With all kinds of red envelopes during the New Year and the dividends of his and Ji Zhuan's profits, Song Jining suddenly found himself a rich man.

Afterwards, Song Jining invested in a lot of stocks, and bought some real estate in the Shenzhen market. Afterwards, he returned to City A due to the notice of the thesis, and bought a courtyard house for him and Ji Yu by the way, and bought several properties with good locations.

In fact, apart from stocks, he had no other investment plans. After all, the factory is now profitable, and he is studying and doing research, so he has no time to run a business.

But he remembered that Ji Lian used to talk about buying a lot of houses when he was rich in the future. He had no money at the time, and now he is not around when he is rich, so Song Jining decided to help him buy it. Let's leave it at the self-selected mall!

Self-selected shopping malls are easy to navigate, Song Jining transferred a few executives from Shenzhen City to take charge of the operation, and went back to school.

Although money can satisfy his material pursuit, Song Jining still feels that research can satisfy his psychological achievement more.

And it's also related to whether he can be with Ji Zhuan.

No amount of money is as important as Ji rafter.

The meeting place was Professor Jiang's laboratory in the Chinese Academy of Sciences. Professor Jiang had brought Song Jining and Ji Yu here. At that time, the two were just ordinary high school students who had developed robots.And now...

Professor Jiang looked complicated.

His two most promising students will not belong to him in the end.

"Professor?" Song Jining saw that Professor Jiang's expression was not good, and asked, "What happened? Did I fail the thesis?"

"No, on the contrary, your paper has passed the review and will be published in the journal "Engineering Discipline" next month." Professor Jiang paused and continued: "Your paper has been recommended by all five review experts. , with these few letters of recommendation, there is no problem for you to enter the training class of the Air Force Guidance Academy."

Song Jining was happy, and Professor Jiang continued: "But, it can only be the next class. The first class has already been trained for half a period, and you can't keep up with the regulations if you enter halfway, so you can only wait until next year."

Song Jining didn't work so hard just to join the Air Guidance Academy, and when he entered, Ji Lian was already over, so what's the point.

"Professor, you specially asked me to come, there must be another way?"

Professor Jiang was silent for a while, and asked: "Can you really not wait for the next session?"

"No!" Song Jining replied firmly.

"I'll take you to meet someone." Professor Jiang got up and led Song Jining to the Academy of Sciences: "He has also read your paper and appreciated your views very much. The most important thing is that he is an engineer of the Air Force Guidance Institute. If you are recommended by him, you will definitely be admitted with an exception."

When Song Jining heard this, he cheered up immediately.

The engineer of the air guidance institute is Zhong Tao, an expert who is the same age as Professor Jiang but has higher qualifications.Professor Jiang's introduction to him was: "The person in charge of the XXXX national project, the person in charge of the XXXX scientific research unit." Song Jining didn't know much about these things, and he was just a rookie in the scientific research circle.But I understood the last sentence.

"The "Precision Mechanics Design" you studied was written by him."

Song Jining was immediately in awe.

"Precision Machinery Design" is an extra-curricular professional book highly respected by Ji Yu, and he has also explained it to him. His research has also quoted the content of this book, so he must respect the original author.

Probably the older generations of scientific researchers have such a personality, and they seldom say polite words. As soon as Song Jining sat down, Zhong Tao immediately asked him various questions in his thesis.Song Jining felt that his pickiness and rigor were stricter than the dissertation defense that the seniors said.

Fortunately, this thesis was indeed completed by himself. He remembered every detail and data clearly, and every answer was well-founded and convincing.

Zhong Tao nodded in satisfaction, and asked Song Jining: "I heard that you want to participate in the training class of the Air Force Guidance Academy?"

"Yes, I want to participate in this session." Song Jining said.

"It's not good to join the class halfway. It doesn't comply with the regulations, and it's easy to be regarded as a back door." Zhong Tao asked: "Can't you wait for the next class?"

"cannot!"

"...Well, that's what Old Jiang said." Zhong Tao looked at Song Jining and said, "I can use my relationship to let you join the class, but you have to promise me one condition."

"What conditions?"

"When you take the postgraduate entrance examination in the future, I hope you will come to my college and become my student."

Song Jining was stunned.

"Think about it, I really appreciate you." Zhong Tao said: "Your paper is so in line with my vision, it's almost as if I wrote it, I hope you can participate in my research, how about it? "

"But I'm Professor Jiang's student..."

"Aren't you a sophomore? How can you count? You're not a formal student." Zhong Tao persuaded:

The author has something to say:

"Besides, students have the right to choose a tutor. Lao Jiang also agreed. He said it depends on your own choice."

Seeing that Song Jining frowned and said nothing, Zhong Tao emphasized: "Look, it's not bad to be my student. I can let you enter the Air Force Guidance Academy and allow you to sign my research. I can assure you that I am definitely a student." Very good tutor for students.”

Song Jining asked: "Professor Jiang agreed?"

"No, but he said it's up to you to choose, and he won't have any objections. If you go to a higher place, I can give you better resources, such as formally entering the Air Force Academy in the future, how about it?"
