Chapter 63： 3 questions

Saturday morning at 9:30.

Outside the conference room door of Guanghua Building, Guanghua University.

There were a bunch of people standing on both sides of the corridor. Although everyone kept their voices low, when they gathered together, their voices were not small.

Li Qing stood in the crowd, looking at so many people, he was in a panic.

She simply counted, there were about a dozen people, and the problem was that the interview time was notified at 10 o'clock in the morning. There are so many coming in half an hour, the ghost knows how many people will be on the way!

"Why are there so many people..." Li Qing was a little uneasy. She looked up at the people around her, and finally found two girls.

His eyes lit up, and after approaching through the crowd, he asked a girl wearing glasses, "Classmate, which school are you from?"

"I'm from Southwest University, where are you, classmate?" The glasses lady replied with a friendly smile.

"I'm from Handong University..." Li Qing asked curiously, "Are you an undergraduate or a graduate student?"

"I graduated with a Ph.D. this year. There should be a lot of masters and Ph.Ds here today, right?" Just as the glasses lady was thinking, Li Qing felt cold in his hands and feet!

Anyone who asks casually is Doctor 211, and she is just an ordinary undergraduate student...

Abandoning the glasses girl, she turned to approach the only remaining sister.

"What school do you go to, classmate?"

"I'm from Fudan University, but I just graduated with a master's degree." Sister Zhi replied nervously.

Li Qing: ...

It's over, the old lady is estimated to be the cannon fodder today!

There were only 3 girls present, including her, but...she was the one with the lowest educational background.

At this moment, she didn't even understand how she received the interview invitation.

Just when she was thinking wildly, there were three people sitting in the conference room.

Chen Hao looked at the form in his hand and asked, "How many interviewees are scheduled today?"

For these data, Chen Chong can no longer be familiar with it, he can recite it completely.

"A total of 51 people were notified, 18 in the morning and 31 in the afternoon."

Chen Chong pushed his glasses, considering that some people would not come, so he notified 51 people.

An average of 10 minutes per person is enough for one day.

"Well, it's almost. When it's 10 o'clock, Deng Hui, you start calling people according to the serial number." Chen Hao told Deng Hui beside him.

"OK."

……

At ten o'clock, the interview begins.

As a person came in, when Chen Chong asked a question, Chen Hao directly threw an insight skill.

In addition to those with high potential value, he will pay attention to it. In terms of materials science, as long as the upper limit is higher than 70 points, he will draw a circle around his name.

When encountering a person above 80, draw two circles directly.

8 people were interviewed, four names were drawn in a circle, and two names were drawn in two circles.

It's just that when the eighth interviewee went down, Chen Hao asked Deng Hui to stop calling.

Pointing at the name of the ninth person with a pen, he asked, "How come there is still a bachelor's degree?"

The first eight people, 6 masters and doctorates, and the remaining 2 are also undergraduates of 985 or 211, only this one is a double-non undergraduate.

"Although this degree is a bit ordinary, I saw her resume and it's quite rich. If you think it's not suitable, Principal, forget it." Chen Chong replied embarrassedly.

"It's nothing, just curious to ask. Our school doesn't focus on academic qualifications, but on ability, and if you have the ability, you can accept both." Chen Hao said with a smile.

She waved her hand, and Deng Hui, who was at the door, watched it and went out.

Li Qing, who had been waiting for a while, waited anxiously. The first few people came out one and the other went in. Why did he go wrong when he arrived?

Are you going to pass me...

While she was thinking wildly, a sound of heaven finally remembered.

"No. 9 Li Qing, you can go in."

"exist!"

Li Qing raised his hand, took a deep breath, and pushed open the door to go in.

The first moment they saw Li Qing, Chen Hao's eyes widened at the same time.

His eyes consciously stayed on the opponent's face.

Because the other party's appearance is really high.

Chen Hao silently used his skills.

"Name: Li Qing

Alignment: Neutral

Potential value: 78

Abilities: Materials Science (70/88), Scientific Research (63/85), Singing (72/78)…”

When Chen Chong asked the question, Chen Hao drew two circles on the name "Li Qing".

Originally, I didn't have any expectations, but I didn't expect that the other party's attributes were not bad.

The upper limit of both materials science and scientific research is more than 80, which is close to 90. Although the ability is average now, the focus is on the high ceiling. He is only 21 years old, and some have time to cultivate.

Although Chen Hao mainly observes a lot and rarely asks questions, he has been listening.

"Because time is limited, I will simply ask you three questions here. Are you ready?"

After Chen Chong finished speaking, seeing the other party nod, he began to ask:

"The first question: How can the relative crystallinity of polymer materials be used to describe the overall crystallization kinetics?"

Li Qing pondered for a while and replied: "In the total crystallization kinetics method, replace G in equation (1) with K1/n or tx-1, where K and n are the crystallization rate constant and Avrami index in the Avrami equation, respectively. , tx is the time when the relative crystallinity reaches x. In general, tx takes the semi-crystallization time t1/2. For the system with obvious secondary crystallization, x selects a lower value such as 0.05 or 0.1.”

Chen Chong nodded. The first question he asked was about polymer materials, and the second question he wanted to ask was about metal materials.

"The second question: Why is ductile iron widely used in cast iron?"

Li Qing didn't think much about this question, and quickly answered: "The graphite of ductile iron is spherical, and its effect on the matrix is ​​minimized, and the utilization rate of matrix strength can reach 70%~90%. Therefore, ductile iron has Much higher mechanical properties than gray cast iron, tensile strength comparable to steel, and greatly improved plasticity and toughness.

Usually σb=(400~900)MPa, δ=2%~18%, at the same time, some excellent properties of gray cast iron are still maintained, such as good wear resistance and shock absorption, low notch sensitivity, good machinability, etc. . It can be concluded that the welding performance and heat treatment performance of ductile iron are better than those of gray cast iron. "

As for the end, Chen Chong intends to ask a simple question.

"The third question: how to know the distance between the central atoms in the crystal structure?"

This is the basic problem of nanomaterials, and the difficulty is very low.

But to Chen Chong's surprise, Li Qing didn't answer.

After sitting there for about 3 minutes, with a blushing face, he finally said in frustration, "Hello, this question... I forgot..."

Li Qing didn't learn much about nanomaterials, and he didn't review it here for the past few days...

For a while, my mind was empty, and I couldn't answer at all.

Chen Chong didn't speak, he just looked at Chen Hao next to him to see if the principal still had any problems.

In his opinion, although the principal has a background in computer science, his research on materials science is far ahead of him!

Chen Hao did ask a question, but Chen Chong didn't expect this question...

"Then let me ask a question, why did you choose the Institute of Guanghua University?"

"Uh, this... do you want to tell the truth?" Because the third question was not answered, Li Qing's mind was a little muddy, and it was probably down!

"Of course to be honest, it doesn't matter if you say it directly." Chen Hao smiled gently.

"Because I saw the salary was quite high, so I was moved."

After speaking, Li Qing regretted it.

"Ha, it's fine, it's quite honest, it's good." Chen Hao laughed dumbly.

What a lovely little girl.

"It's okay, don't be nervous, go back and wait for the notification Oh, okay, thank you leader."

Li Qing went out in a bad mood.

The interviews continued.

Although I made an appointment with 18 people in the morning, there were actually 14 people, and the interview ended at 12:10.

The crowd outside the conference room dispersed, and inside Chen Chong looked at Chen Hao and asked:

"Principal, what do you think of these 14 people?"

"How many do you think you can use?" Chen Hao asked noncommittally.

"I think these 8 people can be recruited." Chen Chong also has a list with the names of 8 people circled with a pen.

Chen Hao glanced at it, then said, "Let's add another Li Qing."

"She? Maybe she has a question that she didn't answer..." Chen Chong replied hesitantly.

Among the 14 people, 11 people answered all the questions. Among the 11 people, 8 people answered very well, and the other 3 people were not standardized and rigorous enough.

As for the mistakes in all three questions, it is not within his scope of consideration.

"I think this Li Qing is very malleable. It's enough to recruit him and train him well. Besides, there can't be too few lesbians in the research institute."

Chen Chong: "..."

Listening to Chen Hao's previous half sentence, Chen Chong could still understand.

Just the second half of the sentence...

Principal, just tell me, did you give it to him because he was good-looking...

Are all leaders like this?

ps: Ask for a recommendation ticket! Thanks to the book friends "12 hours" for the reward of 200 book coins! Thanks! I haven't received a reward for 2 days, I am overjoyed! (The name has a symbol, I can't type it out, it's embarrassing)

Stay up late at night just came out, woo woo woo, I'm going to sleep.

Good night, Makabaka!
