Sail across the sea

Chapter 93 This topic is very interesting

"Ms. Zheng, I applied for exemption from class not to skip classes to play, but to use the time to learn more knowledge. Also, I have to do a project with Mr. Hai." Gao Fan explained with a mournful face.

"What subject are you doing with Mr. Hai?" Yang Kai asked.

Gao Fan took out the papers that Hai Qingwen had read from his schoolbag, handed them to Yang Kai, and said, "When I was at home, I helped my father's factory conduct a research on rare earth catalysts. Teacher Hai felt that I The research is interesting and encourages me to keep doing it.”

"Rare earth catalyst? It's an interesting topic." Yang Kai took over the paper and flipped through it, seeming quite interested.

"The school stipulates that you can only apply for exemption from the first week, and it's already the second week, so even if you pass Teacher Yang's assessment, I can't approve your exemption." Zheng Xiuhua said.

"Ah, this..., then I..."

Gao Fan didn't know what to say.I took off my socks, you said the water is too cold, are you and Yang Kai just kidding me?

What Zheng Xiuhua wanted was Gao Fan's reaction, she waited for half a minute before saying leisurely:
"Since Xiao Yang has passed your test, I confirm that you have such ability. I can say hello to the teacher in charge of the class. In the future, you don't have to go to class every day, and you don't need to do homework. However, you have to take the final exam.

"If you fail the final exam, you are failing and you have to take the make-up exam, and no matter how high your score in the make-up exam is, you can only score 60 points."

It turned out to be like this...

In fact, thinking about it, the school stipulates that the first week is the time for the exempted exam, he missed the time, and no one gave him the exempted exam paper, how could Zheng Xiuhua let him pass?
The current approach, which allows him not to attend classes, but needs to take the final exam, is the unity of principle and flexibility.Zheng Xiuhua is also worthy of being an old man who has worked in educational affairs for more than 20 years, and this measure is quite accurate.

Gao Fan breathed a sigh of relief, and at the same time, he knew a little more about Zheng Xiuhua's black belly.This old lady is so bad, she obviously has a solution, but she insists on whetting her appetite, what kind of character is this!
"Thank you Teacher Zheng, ah no, thank you sister Zheng."

Gao Fan quickly thanked him.This is Zheng Xiuhua's kindness outside the law, and it really can't be justified if he doesn't express his gratitude.

Zheng Xiuhua put on a straight face again, told Gao Fan to study hard, and then went back to his office.When she went out, Yang Kai was still reading Gao Fan's thesis. When Gao Fan sent Zheng Xiuhua out and came back again, Yang Kai raised his head, frowned and said to Gao Fan:

"Gao Fan, in your paper, the ratio of rare earths is completely fabricated, it has not been calculated."

"High! Brother is really tall!" Gao Fan gave Yang Kai a thumbs up and said, "This is indeed a flaw in this paper. However, to calculate an optimal ratio, the model is too complicated , and the amount of calculation is too large for us to complete.”

"Your topic is very interesting." Yang Kai said, "In fact, rare earth catalysts can be used not only in the synthesis of ammonia, but also in petrochemicals, such as the synthesis of ethylene, butadiene, butadiene rubber, etc. get on.

"If you can solve calculation problems, it is equivalent to providing a common calculation method for various industries. This matter is of great value."

"That's what I said, but..."

Gao Fan scratched his head, not knowing what to say.

Of course Gao Fan knew that the calculation of the ratio of rare earths was an important issue.In later generations, there are special calculation programs to solve such problems. Researchers only need to propose models, and all calculations can be done by software.

But now, Gao Fan can't find a ready-made program, nor does he have a computer, so he can't let him calculate the differential equation manually, right?

It is true that he is proficient in mathematical analysis, but the differential equations in the chemical process are not the ones in textbooks. The process of solving the equations is extremely sour and refreshing. He does not think that his youth should be dedicated to these equations.

"If you are not familiar with calculation models, I can help you calculate." Yang Kai said, "I am quite interested in this project. If you do well, you may be able to produce some very good results."

"I can also do modeling, but the calculation is too troublesome, unless there is a computer." Gao Fan said.

Yang Kai nodded and said: "Indeed, to solve this kind of problem, you must have a computer. The school's computer room is very busy. I will apply for it and see if I can apply for a few hours. We will write the program in advance. , when the time comes, just enter it and forget it.”

"Is it difficult to apply for a flight?" Gao Fan asked.

Yang Kai said: "It's very difficult. The school only has one 4341 medium-sized computer, equipped with 40 terminals, which are used by all departments, especially the physics department. They also have cutting-edge national defense projects, which must be guaranteed first.

"Our chemistry department has never needed computers very much, so we are allocated very few slots. If you want to apply for extra slots, you have to queue."

"Is that so?"

Gao Fan thought for a while, nodded and said, "That's fine. Otherwise, brother, I'll leave this paper with you for now, and you can see how to solve the calculation problem. At that time, this paper will count as a collaboration between the two of us." Yes, you are the first author and I am the second author.”

"That's not necessary." Yang Kai waved his hand. "The main contribution of this paper is yours. Of course, you are the first author. Let me think about it. Maybe I can start from your paper and propose a catalyst calculation model. Write it separately." A paper, when the time comes, I will give you a second author, what do you think?"

"Of course I have no objection." Gao Fan said with a smile.

Gao Fan really didn't care about such things as the author of the paper.If he wants to be famous, he plagiarizes a few discoveries of later generations, writes a few articles and submits them to Science, and they are guaranteed to be published. At that time, he will be the Taishan Beidou in a certain field in the international chemical community, and he still needs to worry about an article on rare earth catalysts. Whose name is the article department?

According to the basic law of time travel, the time traveler should keep a low profile, and Gao Fan would not make such a mistake.

"Then you will come to work in the reference room tomorrow?" Yang Kai said.

"Huh?" Gao Fan was a little puzzled.

Yang Kai said with a smile: "Didn't Grandma Zheng agree that you don't have to go to class? What else can you do if you don't go to class? It's better to go to the reference room to look at the materials. We have some chemical materials here, which are not available in the school library." .

"I think you are quite talented in scientific research. Read more materials, maybe you have some good ideas, and we can discuss a few weighty articles."

"Okay, let's do what my brother said." Gao Fan said, "However, it won't work tomorrow. The engineer from our factory I mentioned just now is in Beijing now, and I want to visit her."
