I Don’t Want to Win Lying Down

Regarding Yang Xiaoman's miraculous operation, Xu Mang only looked at a loss, saying that if he bought the flowers himself, would he die? Be sure to make it mysterious, deliberately make yourself angry to be happy, in other words... I seem to be this kind of person too.

...

I remember you asked me to buy you a car? Xu Mang pretended to be indifferent and said, When I make money, I will buy it for you.

cut!

You miser. Yang Xiaoman lay on top of Xu Mang, and said with a disapproving expression, You always use some excuses to fool me, besides, the car I want to buy is quite expensive, and the money you earned from your thesis may not be enough .”

hey-hey!

Xu Mang hugged Xiaoman suddenly, and said with a smile, I'm researching a material that can be sold for a lot of money.

Yang Xiaoman rolled her eyes, and said calmly: I believe you bastard, you bastard is very bad.

real!

A component material used for nuclear fusion energy reactors. I am in charge of the research and development of this component, and then they purchase it. Xu Mang said arrogantly, Am I awesome?

Yang Xiaoman frowned, and ruthlessly broke Xu Mang's fantasy: You are a theoretical physicist, do you know what a material is? You have calculated many things based on pure theory, but what you are facing now is that you need to The product of an experiment, can you big fool?

Xu Mang shook his head: I use the quantum database I just developed to calculate the possibility from a theoretical point of view. As for the experiment...others will do it.

snort!

Then what... can you teach me quantum mechanics? Yang Xiaoman curled up in Xu Mang's arms and said creakingly: I was recommended to graduate school, but I want to graduate sooner. Write a paper on the future of fission and fusion economies, using quantum economics as a cornerstone.

ah?

What the hell?

Economics has begun to involve quantum mechanics?

Xu Mang looked at Xiaoman in his arms with a confused face. He didn't even understand quantum economics, and the fission economy and fusion economy behind him were even more unheard of.

What is quantum economy? Xu Mang asked.

Fool!

This is the stock market option pricing model established by Scholes, which won the Nobel Prize in Economics. Later, game theory experts launched a quantum economic model based on quantum economics. Yang Xiaoman explained: This is the current Cutting edge model.

Xu Mang still didn't understand, and asked curiously, I still don't understand.

It's normal if you don't understand the subject of studying and exploring the laws of quantitative change in economic things. Yang Xiaoman raised his head and said silently: From now on, spare an hour every night to help me finish the thesis together. You are in charge of the quantum mechanics part.

oh...

the next day,

Xu Mang got up at six o'clock in the morning, let go of Xiaoman's clenched hand, bought some breakfast after getting dressed, started his own work, established a systematic framework from the performance requirements, and carried out work according to this framework. Relative research.

According to the performance requirements, Xu Mang can infer that this component may not be made of a single material, but needs to be combined with multiple materials. The components formed by the connection process generally need three kinds of materials, which meet the requirements of metal materials, composite insulating materials and external parts. Insulation strengthening materials, among which composite insulation materials have relative mechanical performance requirements.

Immediately afterwards,

Xu Mang made a table, the performance parameters of metal materials and composite insulating materials,

Consider the comprehensive index of performance from four angles: elastic modulus, shear modulus, shrinkage rate and Poisson's ratio.

well?

Why are you so early? Yang Xiaoman glanced at Xu Mang, and said slightly dissatisfied, Don't make any noise, I don't have class today... remember to order takeaway at noon.

Um.

Xu Mang responded casually and continued with the work at hand.

After having the performance parameters, the following is to plan the design standards for metal materials and composite insulating materials. According to the requirements in the document, Xu Mang first needs to calculate the strength, yield stress, allowable stress, and compression in the layer thickness direction of the two materials. Strength, shear gravity...

but...

Xu Mang found himself in a daze. Although he had the ability to integrate systems, this already involved engineering knowledge. How to calculate the allowable stress?

Sorry...don't even know the formula.

It's over, it's over...

There must be a professional material science student who can do the calculations for me. Xu Mang thought about it for a while. This talented student must have been in school for two and a half years, and what else should he know? The minimum standard must be Member of Fuda basketball team.

go to the balcony,

Xu Mang called Liu Zhuo, a former member of the research team, for help.

Is it Liu Zhuo?

Professor Xu...it's only after six o'clock? After receiving Xu Mang's call, Liu Zhuo's tone was full of helplessness, and he said, Is there anything you can do with me?

I remember that you have been in school for two and a half years, right? Xu Mang said with a smile, I still remember that you formed a rap band when you were a freshman, and you were the lead singer of the band, and you were also a member of the basketball school team?

Liu Zhuo said: Yes.

do not talk!

Professor Xu needs you! Xu Mang said seriously, Come or not!

Liu Zhuo smiled wryly, Professor Xu...I'm really busy recently.

What are you busy with? Xu Mang asked.

I'm busy with class. Liu Zhuo said, I may not have enough credits.

Don't panic!

The director of your department, Liu Guofang, Director Liu, is an old friend of mine. Xu Mang said with a smile, As long as I ask, he won't let me go, uh...I'll go find Liu later. The director asked you to come here, and get some benefits from him by the way.

Liu Zhuo suddenly became interested, and hurriedly said: Fuck, is Professor Xu real?

Remove the word ?, and only the truth remains. Xu Mang said, Do you know the formula for the allowable stress?

Know!

...

nine o'clock,

Xu Mang brought the documents to the director's office in the Department of Materials Building.

hey-hey.

Director Liu? Xu Mang came to Director Liu with a smile, his professional smirk betrayed Xu Mang's purpose at the moment, and said, Is Director Liu busy?

...

There is a legend circulating in Fuda that if Xu Mang smiles, something will happen.

Director Liu looked at Xu Mang's professional smirk, and was speechless for a while, and asked, I'm pretty busy.

oh...

Director Liu, can you lend me someone? Xu Mang asked.

who?

Liu Zhuo.

Liu Zhuo? Director Liu thought for a while, then nodded and said, Yes.

Originally thought it would be a tug-of-war, but Director Liu just thought for a moment and agreed without asking. Xu Mang felt that there was only one reason to explain why. Director Liu probably didn't know who Liu Zhuo was.

Then what...Liu Zhuo doesn't have enough credits, can he be exempted from the exam this semester? Xu Mang asked.

Xu Mang?

You're going too far! Director Liu said with black lines all over his face, I don't have such a request from you.

Xu Mang expected such a thing to happen, so he took out a document and said to Director Liu: Director Liu... this is a research project entrusted to me by the International Nuclear Energy Agency, you must agree, otherwise you will It will delay the happiness of all mankind.

I...

this...

Director Liu glanced at the cover of the document and didn't know what to say for a while.

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

When I was at Nanjing University. Xu Mang said, In short, I can only show you the cover. Some of the contents inside are confidential. I have signed the contract. Director Liu... the exemption from the exam...how do you say it?

Director Liu said helplessly: Exemption from the exam is impossible, but under reasonable conditions, appropriate adjustments can be made. Do you understand what I mean?

Understand!

hey-hey...

After solving Liu Zhuo's problem, he called Liu Zhuo and told him the good news. Of course, in Xu Mang's narration, he made some artistic exaggerations.

Fuck!

Professor Xu...you are so awesome! Liu Zhuo said excitedly after knowing that he had obtained the permission: Are we really members of the International Nuclear Energy Agency?

Can this be fake?

I'll wait for you in the old lab. This is the personal lab I applied for. Xu Mang said, Hurry up, our time is limited!

Um!

moment,

Liu Zhuo came to the laboratory.

Xu Mang didn't talk nonsense, and directly handed over all the calculation problems to Liu Zhuo, and repeatedly emphasized confidentiality and accuracy, especially in terms of accuracy, only 100% correct, and no mistakes should be made.

Professor Xu... It's too much to be wrong. Liu Zhuo said with a worried face: I'm afraid my ability is limited.

There is no room for negotiation. Xu Mang said seriously: In short, you must make no mistakes, which are related to nuclear fission, so there is only success, no failure.

finally,

Liu Zhuo had no choice but to unconditionally agree to Xu Mang's request, and began to calculate the metal materials and composite insulating materials. Under Xu Mang's framework, Liu Zhuo had to calculate the six strengths of the two materials.

Well?

A formula? Xu Mang stood by and watched for a long time, and found that what Liu Zhuo was doing was all a formula, so he said with a dark face, Is it so simple?

Um!

It's okay. Liu Zhuo said: For example, the maximum equivalent and allowable stress of metal materials is determined according to the formula Sm=Min(2/3Sy, 1/3Su), where Sy and Su are the maximum yield stress and maximum strength.

According to the performance index you gave, at the temperature of 4.5K, the maximum strength of the metal material is 1440MPa, the yield stress is 450MPa, and the allowable stress is 300MPa... Liu Zhuo continued: At the temperature of 300K, the maximum strength is 500MPa , the yield stress is 170MPa...

paused,

Liu Zhuo said: According to my understanding of materials, this metal material is generally 316 stainless steel that has been nitrided.

What about the composite insulating material? Xu Mang asked.

For composite insulating materials... According to my calculations, the probability is fiber-reinforced composite materials. This material is characterized by non-conductivity, high mechanical strength, and corrosion resistance. Liu Zhuo said: There are many kinds of fiber-reinforced composite materials. , but I'm leaning towards GFRP material.

Xu Mang: 囧

Fuck!

Isn't this just fiberglass!

People look for him thousands of Baidu.

Looking back suddenly, the man was there, in a dimly lit place.

Does it need to be modified? Xu Mang asked, The performance index of the glass fiber reinforced plastic doesn't seem to meet the requirements?

Yes!

It is not only the modification of FRP, but also the 316 stainless steel that has been nitrided. Otherwise, it is impossible to meet your performance index requirements based on the performance of the raw materials. Liu Zhuo said seriously: Professor Xu, your There is one important piece of information missing from the performance metrics requirement, as if you didn't give specific direction.

For example, the elastic modulus lacks the thickness direction, axial direction and winding direction. Liu Zhuo said.

Xu Mang nodded: I will re-edit it later. Today, Wednesday... This weekend, the two of us will research the materials, and you will be responsible for the modification. Do you have any requirements for the software?

have!

I hope that the quantum analysis software can have the function of fluid dynamics analysis. Liu Zhuo said shyly: Professor Xu...I know this request is a bit excessive, but one of your requirements is low temperature stress load The airtightness under…”

Xu Mang thought for a while, and said calmly, This request is not excessive at all, and this function will be available on the software tomorrow!

Liu Zhuo:? ? ?

this...

Sure?

Are you kidding me?
