Chapter 352

For Yang Xiaoman's magic operation, Xu mang only a face at a loss, said a flower is his own purchase will die? We must make it mysterious. We can only be happy when we deliberately get angry. We seem to be such people.

"..."

"I remember you wanted me to buy you a car?" Xu mang pretended to be indifferent and said, "when I make money, I will help you buy it."

"Cut!"

"You miser." Yang Xiaoman was lying on Xu Mang's body, with a look of disapproval and said: "always take some reasons to fool me. Besides, the car I want to buy is very expensive, and you may not earn enough money for your thesis."

"Hey, hey

Xu mang suddenly hugged Xiaoman and said with a smile, "I'm studying a material that can sell for a lot of money."

Yang Xiaoman white one eye, calmly said: "I believe you a ghost, you this bastard is very bad."

"Really!"

"I'm responsible for the research and development of a component material for a fusion energy reactor, and then they purchase it." Xu Mang's face full of pride and coquettish ground says: "am I a cow force?"

Yang Xiaoman frowned, mercilessly broke Xu Mang's Fantasy: "you are a theoretical physics, do you know what is material? Many of your things are calculated by pure theory, but what you are facing now is the product that needs to be tested. Can you be such a fool? "

Xu mang shook his head: "I use the quantum database just developed to calculate the possibility from the theoretical point of view, about the experiment... Others will do it."

"Hum!"

"What... Can you teach me quantum mechanics?" Yang Xiaoman shrank in Xu Mang's arms and squeaked, "I was not recommended to graduate school, but I want to graduate faster. At present, I am writing a paper on the future of fission economy and fusion economy based on quantum economics."

Ah?

What?

Economics is all about quantum mechanics?

Xu mang looks at Xiaoman in his arms. He doesn't even know what quantum economics is. What fission economy and fusion economy are behind him are unheard of.

"What is quantum economy?" Xu asked.

"Fool!"

"This is the stock option pricing model established by Scholes and won the Nobel Prize in economics. Later, game theory experts based on quantum economics put forward the quantum economic model." "This is the most avant-garde model at the moment," Yang explained

Xu mang still can't understand, curiously asked: "still can't understand."

"It's normal that you don't understand the discipline of studying and exploring the law of quantitative change of economic things." Yang Xiaoman raised his head and said in silence: "in the future, spare an hour every night to help me finish the paper. You are responsible for the part of quantum mechanics."

"Oh..."

the next day,

Xu mang got up at six o'clock in the morning, loosened Xiaoman's hand, bought some breakfast after wearing his clothes and trousers, and started his own work. He established a systematic framework from the performance requirements, and conducted relative research according to this framework.

According to the performance requirements, Xu can infer that this part may not be a single material, but need to be combined with a variety of materials. The components composed by connection process generally need three kinds of materials, which meet the requirements of metal materials, composite insulation materials and external insulation reinforcement materials. Among them, composite insulation materials should have relative mechanical properties.

Next,

Xu mang made a table. The performance parameters of metal materials and composite insulation materials were considered from four aspects: elastic modulus, shear modulus, shrinkage and Poisson's ratio.

"Ah?"

"Why are you so early?" Yang Xiaoman looked at Xu Mang and said slightly dissatisfied: "don't make a sound. I don't have a class today. Remember to order takeout at noon."

"Well."

Xu mang answered casually and went on with his work.

With the performance parameters, the following is the design standards for metal materials and composite insulation materials. According to the requirements of the document, Xu mang first calculates the strength, yield stress, allowable stress, compressive strength along the layer thickness direction and shear force of the two materials...

but...

however, Xu mang found himself confused, even though he has systematic integration Ability, but this already involves the knowledge of engineering, how to calculate the allowable stress?

I'm sorry... I don't even know the formula.

"It's over..."

"I have to have a professional material student to help me calculate." Xu mang pondered for a moment that this high-quality student must have been in school for two and a half years, and what else would he have to know, right? The minimum standard must be a member of the basketball school team of the national rejuvenation University.

After walking to the balcony,

Xu mang called Liu Zhuo, a member of the research group, for help.

"Liu Zhuo?"

"Professor Xu... It's just over six o'clock?" After receiving Xu Mang's call, Liu Zhuo's tone was full of helplessness and said, "what can I do for you?""I remember you were in school for two and a half years, right?" Xu mang said with a smile: "I still remember when you were a freshman, you set up rap band, was the lead singer of the band, but also a member of the basketball school team?"

"Yes," Liu said

"Stop it!"

"Professor Xu needs you!" Xu mang said seriously, "come or not!"

Liu Zhuo said with a bitter smile: "Professor Xu... I'm really busy recently."

"What are you up to?" Xu asked.

"Busy with class." "I may not have enough credits," Liu said

"Don't panic!"

"Liu Guofang, director Liu of your department, and I are old friends." Xu mang said with a smile: "as long as I open my mouth, he won't let people go. Er... Wait a moment, I'll go to Director Liu to ask you to come over and take some welfare from him to you."

Liu Zhuo immediately came interested and said in a hurry: "lie trough, Professor Xu really?"

"Remove the word" Mo "and leave the real one." "Do you know the formula of allowable stress?" Xu said

"Yes!"

At nine o'clock,

Xu mang came to the director's office of the materials department building with his documents.

"Hey, hey."

"Director Liu?" Xu mang came to Director Liu with a smile. The professional fake smile betrayed Xu Mang's purpose at the moment and said, "is director Liu busy?"

"..."

there is a legend in Fuda. Xu mang smiles, and it will be no good.

Director Liu looked at Xu Mang's professional smirk. He was speechless for a while and asked, "very busy."

"Oh..."

"can director Liu lend me someone?" Xu asked.

"Who?"

"Liu Zhuo."

"Liu Zhuo?" Director Liu thought for a moment, nodded and said, "well."

Originally thought that this would be a seesaw battle. As a result, director Liu only thought for a moment and agreed without asking. Xu mang felt that there was only one reason to explain why. It was estimated that director Liu did not know who Liu Zhuo was.

"Then what... Liu Zhuo's credit is not enough, can you exempt this semester?" Xu asked.

"Xu mang?"

"You're going too far!" Director Liu said with a black line on his face: "there is no such requirement from you."

Xu mang expected that such a thing would happen. At this time, he took out a document and said to Director Liu: "director Liu... This is the research project assigned to me by the international nuclear energy agency. You must promise, or you will delay the happiness of all mankind."

I...

this...

director Liu took a look at the cover of the document and did not know what to say for a while.

"How did you get along with this organization?" Director Liu asked.

"At NTU." Xu mang said: "in short, I can only show you the cover. Some of the contents are confidential. I have signed a contract. Director Liu... How can I say this exemption?"

Director Liu reluctantly said: "it is impossible to exempt from the examination, but under reasonable conditions, you can adjust appropriately. Do you understand what I mean?"

"Yes

"Haha..."

after solving Liu Zhuo's problem, he called Liu Zhuo and told him the good news. Of course, Xu Mang's narration naturally made a kind of artistic rendering.

"Lying trough!"

"Professor Xu... You're so cool!" When Liu Zhuo knew that he had obtained the permission, he said excitedly, "are we really members of the international nuclear energy agency?"

"Can it be fake?"

"I'll wait for you in the old lab. this is the personal Lab I applied for." "Hurry up, we have limited time," Xu said

"Well!"

After a moment,

Liu Zhuo came to the laboratory.

Xu mang didn't talk nonsense. He directly handed all the calculation problems to Liu Zhuo, and repeatedly stressed the confidentiality and accuracy. Especially in terms of accuracy, only 100% of them were correct and no mistakes could be made.

"Professor Xu... This can't be wrong. It's a little too much." Liu Zhuo said with worry on his face: "I'm afraid my ability is limited."

"There is no room for discussion." "In a word, you have to make sure that there are no mistakes, it is related to nuclear fission, so only success, no failure," Xu said solemnly

Finally,

Liu Zhuo could only promise Xu Mang's request unconditionally, and began to calculate metal materials and composite insulation materials. Under Xu Mang's framework, Liu Zhuo had to calculate six kinds of strength of the two materials.

"Eh?"

"Formula?" Xu mang stood on the edge and looked at it for a long time. He found that Liu Zhuo was doing a set of formulas. He immediately said with a black face: "so simple?"

"Well!"

"Not bad." "For example, the maximum equivalent and allowable stresses of metallic materials are determined by the formula SM = min (23sy, 13su), where sy and Su are the maximum yield stress and the maximum strength respectively," Liu said"According to your performance index, at 4.5K, the maximum strength is 1440mpa, the yield stress is 450MPa, and the allowable stress is 300mpa..." Liu Zhuo continued: "at 300K, the maximum strength is 500MPa, the yield stress is 170Mpa..."

pauses for a moment,

Liu Zhuo said: "according to my understanding of materials, this kind of metal materials are generally infiltrated Nitrogen treated 316 stainless steel. "

"What about composite insulation?" Xu asked.

"Composite insulation material... In my calculation, the approximate rate is fiber reinforced composite, which is characterized by non-conductive, high mechanical strength and corrosion resistance." "There are many kinds of fiber reinforced composites, but I prefer GFRP," Liu said

Xu Mang: I'm sorry to see you lying in the trough!

This is not fiberglass!

Search for him in the crowd.

Suddenly looking back, the man was in the dim light.

"Is it necessary to modify it?" "It seems that the performance index of FRP can not meet the requirements," Xu asked

"Yes

"It is not only to modify FRP, but also to nitrided 316 stainless steel. Otherwise, it is impossible to meet your performance requirements with the performance of raw materials." Liu Zhuo said seriously: "Professor Xu, you still lack an important information about the performance requirements. It seems that you have not given the specific direction."

"For example, the modulus of elasticity lacks thickness direction, axial direction and winding direction." Liu Zhuo said.

Xu mang nodded: "wait a minute, I'll revise it again. Today, Wednesday... This weekend, we'll work out the materials. You'll complete the modification. Do you have any requirements for the software?"

"Yes!"

"I hope to have the function of fluid dynamics analysis in quantum analysis software." Liu Zhuo said sheepishly, "Professor Xu... I know that this requirement is too much, but one of your requirements is the air tightness under low temperature stress load..."

after thinking for a while, Xu mang calmly said, "this requirement is not excessive at all. This function will be available in the software tomorrow!"

Liu Zhuo:???

This...

OK?

No kidding?
