Vol 2 Chapter 612: Only 1 person was in the drum

When Qin Hai was observing Cui Xuezhe, Cui Xuezhe was also observing the future big brother. When Qin Shan just told him that his brother was going to meet him, he was a little nervous. The place where he was nervous was not because he was inadequate, but he was worried that it would be difficult for workers in a small factory like Qinhai Deal with.
People often say: In the eyes of Jingcheng people, all people are foreigners; in the eyes of Pujiang people, all people are rural people; as for the people of another city, all people can Divided into edible and inedible ...
As a child who grew up in Beijing, Cui Xuezhe has a superficial understanding of "outside". Although most of his university and graduate classmates are outsiders, he feels that this is a small group of well-educated outsiders and does not represent true outsiders. In his mind, foreigners, especially workers in small counties, should be rough-headed and have some original ecological habits.
Yesterday, after arranging the meeting the next day, Cui Xuezhe didn't fall asleep all night, using his head used to doing scientific reasoning, to simulate countless kinds of plans when meeting with Qin Hai: In case Qin Hai was prejudiced against scholars How to do? What if Qin Hai is full of swear words? What if Qin Hai wants to help find a job in Beijing ...
He couldn't even talk to his parents about these concerns. He used to talk about his father's views to foreigners in the past, but he learned a lot from his father, saying that he was too detached from the masses and needed to go to the poor and middle peasants to receive some re-education. He knew that his father always respected ordinary workers and peasants in the local area. Because of this, he didn't worry that his parents would abandon Qin Shan's family background. It's just that it's easy to talk. It's so easy to meet everyone. In the case of Qin Hai, the elder brother's brother, he behaved too badly. Will parents be annoyed?
Cui Xuezhe finally came to the bottom of this meeting effort just now. Qin Hai, dressed in blue cloth overalls, looks like a worker with a good personality, and he treats people with things. It's also quite polite, apparently well-educated. He shook hands with Cui Xuezhe very well. It's not the kind of timid and unaccustomed to shaking hands with people, or the rough way of pinching each other's hands when they come up. From this little detail, Cui Xuezhe has an infinite favor for Qin Hai.
After hearing Qin Hai's inquiries about his major, Cui Xuezhe quickly responded in a low-key manner: "I'm doing material science research, and I focus more on small-scale metal materials."
"Small scale?" Qin Hai felt a little curious about Cui Xuezhe's answer, because it really didn't sound like a professional wording.
"Well, it's very small materials ... Let's say, don't you use the unit of" silk "in the machinery factory? The scale of the material I studied. It is equivalent to one thousandth of a silk, or even It's one in ten thousand ... "Cui Xuezhe explained wistfully.
"Haha!" Qin Hai finally understood. This is because the prospective brother-in-law is worried that his education level is too low to understand their technical terms, so he is introducing him in popular terms. One wire in the factory refers to one hundredth of a millimeter, which is 10 micrometers, and one ten thousandth of a wire is one nanometer. In other words, this prospective brother-in-law is studying nanomaterials.
"You mean Nami?" Qin Hai said the answer for Cui Xuezhe. Thinking of his sister's call to himself, he wanted to explain concisely: "I heard the technician in the factory talk about this kind of thing, what nanotechnology is very advanced."
"Yes, I'm studying nanomaterials." Cui Xuezhe replied happily. "It turned out that Brother Qin loved to study, and he even knew nanometers."
Hearing Cui Xuezhe complimenting Qin Hai, Qin Shan grinned desperately, turning her face purple. In Cui Xuezhe's mind, Qin Hai is just a graduate of a technical school. It is really difficult to know the concept of nanometer. Be regarded as a more positive performance. But Qin Shan knew that his brother's accomplishments in materials science were far from what Cui Xuezhe could expect. Tranquility is doing superconducting research, and Qin Shan's own chemical process research. All have been instructed by Qin Hai. Cui Xuezhe praised Qin Hai for his research because of the word nanomaterial, and did not know whether to praise Qin Hai or depreciate Qin Hai. All in all, this is ridiculous.
But at this time, she couldn't speak out to remind her boyfriend, because Qin Hai's identity was deliberately kept secret by herself, and it was the result of her asking for such an oolong. Even if she wanted to reveal it, she would have to wait until today.
Qin Hai, however, became interested in Cui Xuezhe's research direction. He asked with a smile: "There are many kinds of metal nanomaterials. What kind of research do you do, Xiao Cui?"
Cui Xuezhe did not dare to underestimate Qin Hai, he replied cautiously: "The research I am doing now is about the magnetic properties of nano-sized pure iron. Does Brother Qin know anything about this?"
"I have seen some in a book." Qin Hai said. In the previous life, he was a postdoc in the Institute of Materials, so when he heard that Cui Xuezhe was a PhD in the Institute of Materials, he had some kind feelings. Materials have been accumulated for many years in the research of nanomaterials. The previous Qin Hai and the research institutes in nanotechnology have very good relations, and they have also done some research in this area. Now hearing Cui Xuezhe talking about professional matters, Qin Hai feels a bit ticklish.
"The magnetic properties of nanomaterials have a great relationship with the particle size. As the particle size decreases, the magnetic domain of the material changes from a multidomain structure to a single domain structure, so that the mode of magnetization reversal will change from domain wall to magnetic Domain rotation causes a large increase in coercive force, right? "Qin Hai said with a smile.
"Ah?" Cui Xuezhe was completely stupid, his eyes glared at Qin Hai, and his mouth was open to fit a fist. Qin Hai knows that the concept of nanomaterials is more or less acceptable to Cui Xuezhe. This discussion of magnetic domains and coercive force has completely overturned the image of an ordinary young worker in Cui Xuezhe's mind. When does a young worker in a county know so much? It's clear ... is it just what the doctor needs to say when he answers?
"Brother!" Qin Shan was anxious, and Qin Hai showed it down again, but it was completely exposed. When she had a clever idea, she dragged Qin Hai's placket severely and reprimanded: "Brother, did you read two articles with me yesterday, and you came back to bully Xuezhe today? What you said, you You do n’t understand it, do you?

"Of course I don't understand, so I just asked Xiao Cui for guidance. Xiao Cui, the words I just read were read from Xiao Shan's book. I thought it was fun and memorized it, but what it means I don't understand anything, can you explain it to me? "Qin Hai laughed. Of course, he didn't have enough to say those words. He wanted to use these contents to test Cui Xuezhe's knowledge and see if this doctor was a fake.
For Qin Hai's explanation, Cui Xuezhe can only be doubtful. The reason for the doubt is that I feel that Qin Hai's back is a bit strange. This kind of academic judgment is that ordinary people will misread the book. How can Qin Hai be so familiar? As for the reason for believing, it is from Qin Hai's education and identity. If this is not what Qin Hai sees from the book, then Qin Hai is simply a monster.
He certainly did not expect that Qin Hai was indeed a demon evil, and it was a big demon evil.
"The coercive force of a magnetic material is the external force required to change its magnetism. The segment just described by Brother Qin is exactly what we are currently studying. We have measured that the coercive force of massive pure iron is only 20 to 100 amps. Per meter, but when pure iron is made into ultra-fine particles of about 16 nanometers, the coercive force can reach 80,000 amps per meter, with permanent magnet characteristics. We are trying to make smaller iron ultra-fine particles, hoping to get coercive New materials with stronger power. "Cui Xuezhe said to Qin Hai seriously, as he discussed with his colleagues.
"Really? That's really amazing." Qin Hai said haha.
Just then, there was a footstep outside the door, and Cui Xuezhe's eyes lit up, and he got up and said, "My dad is here, I'll meet him."
Qin Hai and Qin Shan both stood up, Cui Xuezhe went out of the room door, and led a middle-aged man in shortly after. With a shy smile on his face, he pointed at Qin Hai and Qin Shan and introduced them to his father: "Dad, let me introduce you, this is Qin Shan, this is Qin Shan's brother ..."
"It's you ..." Cui Xuezhe's father looked at Qin Hai ~ EbookFREE.me ~ and immediately held his arms up, raised his finger to Qin Hai, I don't know what to say.
Qin Hai quickly rushed forward, bowed slightly to his father, and said, "Uncle, my name is Qin Hai. I am a worker at Qingfeng Agricultural Machinery Factory in Anhe Province. I'm glad to meet you ..."
Then, he passed a meaningful look to Father Cui, which meant that the other party should never wear out.
"Anhe, Qingfeng Agricultural Machinery Factory, this ... Oh, okay, okay, welcome and welcome, Comrade Xiao Qin to Beijing." Father Cui was also a wise man, and suddenly understood Qin Hai's suggestion, just a little By mistake, he accepted Qin Hai's self-introduction with a smile, and at the same time reached out his hand and held a tight grip with Qin Hai.
Cui Xuezhe is really a nerd, standing aside, I didn't see Qin Hai and Qin Shan's expressions fluctuate at this moment, and she didn't understand Qin Shan's glance flying towards herself. For a long time, only one of the people in this room was blindfolded, because Qin Hai and Qin Shan both knew his father, and his father was quite long with Qin Hai and Qin Shan. Familiar with.
The middle-aged man, whom Cui Xuezhe called an official cadre, was Cui Hongchun, deputy minister of agriculture. (To be continued)
