When Qin Hai was observing Cui Xuezhe, Cui Xuezhe was also observing the future eldest brother. When Qin Shan first told him that his brother was going to meet him, he was a little nervous, not because he had any shortcomings, but because he was worried that it would be difficult to deal with the workers in a small factory like Qin Hai.

People often say: in the eyes of the people of the capital, all people are outsiders; In the eyes of Pujiang people, all people are countrymen; In the eyes of the people of another city, all people can be divided into those who can eat and those who cannot eat......

As a child who grew up in Beijing, Cui Xuezhe's understanding of "other places" is very superficial. Although most of his college and graduate classmates were outsiders, he felt that they belonged to the well-educated minority of the out-of-town group and did not represent the real out-of-towners. In his mind, outsiders, especially workers in small counties, should have a relatively www.uuxs.cc good personality and have some primitive living habits.

Yesterday, after arranging the meeting the next day, Cui Xuezhe didn't sleep all night, and used his brain, which is accustomed to scientific reasoning, to simulate countless plans for meeting Qin Hai: What if Qin Hai is biased against readers? What if Qin Hai is full of swear words? What if Qin Hai wants to help him find a job in the capital......

He couldn't even talk to his parents about these worries. In the past, he had told his father about his views on outsiders, but he was taught a good lesson by his father, saying that he was too detached from the masses and needed to go to the poor middle peasants to receive some re-education. He knew that his father had always respected the ordinary workers and peasants in the local area, and because of this, he was not worried that his parents would dislike Qin Shan's family background. It's just that it's easy to talk about it usually, but it's really so bad that everyone meets, in case the eldest brother Qin Hai is too bad. Will parents be annoyed?

After meeting just now, Cui Xuezhe's heart finally settled down. Qin Hai, who was wearing blue cloth overalls, looked like a worker with an honest personality, and he treated people and things. There is also some politeness, and it is obvious that he is well-educated. He shook hands with Cui Xuezhe very well. It's not the kind of timid and unaccustomed to shaking hands with people, nor is it the rough style of squeezing the other person's hand as soon as it comes up. From this small detail, Cui Xuezhe had an infinite affection for Qin Hai.

Hearing Qin Hai ask about his major, Cui Xuezhe hurriedly replied in a low-key manner: "I am doing materials science research, and I focus more on metal materials with relatively small scales. ”

"The scale is relatively small?" Qin Hai felt a little strange about Cui Xuezhe's answer, because it really didn't look like a professional's wording.

"Well, it's a tiny, tiny material...... Let's put it this way, don't you use the unit 'silk' in the machine shop? I study the scale of the material. It's equivalent to one thousandth of a silk, or even one thousandth of a ten-thousandth......" Cui Xuezhe racked his brains to explain.

"Haha!" Qin Hai finally understood, this was because the prospective brother-in-law was worried that his education was too low and he couldn't understand their professional terms, so he was introducing it to him in layman's terms. In the factory, 1 filament refers to 1 hundredth of a millimeter, that is, 10 microns, and 1/10,000th of a filament, which is 1 nanometer. In other words, his quasi-brother-in-law is researching nanomaterials.

"You're talking about nano, right?" Qin Hai said the answer for Cui Xuezhe. Thinking of his sister's advice to him, he explained again: "I heard the technicians in the factory talk about this kind of thing, what kind of nanotechnology. Very deep. ”

"Yes, yes, I'm working on nanomaterials." Cui Xuezhe replied happily, "It turns out that Brother Qin loves to study, and he even knows nano. ”

Hearing Cui Xuezhe praise Qin Hai, Qin Shan desperately held back a smile and held back her face. In Cui Xuezhe's mind, Qin Hai is just a technical school graduate, and it is indeed not easy to know the concept of nano. It's a more positive table. But Qin Shan knew that her brother's attainments in materials science were far beyond Cui Xuezhe's reach. Tranquility is doing superconductivity research now, as well as Qin Shan's own research on chemical processes. They have all been instructed by Qin Hai. Cui Xuezhe praised Qin Hai for his love of research because of the word nanomaterials, and he didn't know whether to praise Qin Hai or belittle Qin Hai, all in all, this is too ridiculous.

But at this time, she couldn't remind her boyfriend out loud, because she deliberately wanted to keep Qin Hai's identity secret, and making such an oolong was also the result of her own self-inflicted trouble. Even if she wanted to reveal it, she would have to wait until after today.

Qin Hai was interested in Cui Xuezhe's research direction, and he asked with a smile: "There are many kinds of metal nanomaterials, what kind of research do you do specifically, Xiao Cui?" ”

Cui Xuezhe didn't dare to underestimate Qin Hai anymore, he replied cautiously: "The research I am doing now is about the research on the magnetic properties of nanoscale pure iron, does Brother Qin know anything about this aspect?" ”

"I've seen some in a book." Qin Hai said. In his previous life, he was a postdoctoral fellow at the Institute of Materials, so when he heard that Cui Xuezhe was a doctor from the Institute of Materials, he had some cordial feelings. The Institute of Materials has many years of accumulation in nanomaterial research, and Qin Hai in his previous life had a very good relationship with several nano research bulls in the institute, and he has also done some research work in this area. Now hearing Cui Xuezhe talk about professional things, Qin Hai has a feeling of itching.

"The magnetic properties of nanomaterials have a great relationship with the particle size, and with the decrease of particle size, the magnetic domain of the material changes from a multi-domain structure to a single-domain structure, so that the mode of magnetization reversal will change from the domain wall to the rotation of the magnetic domain, so that the coercivity of the material will be greatly improved, right?" Qin Hai said with a smile.

"Huh?" Cui Xuezhe was completely dumbfounded, his eyes glared at Qin Hai, and his mouth was open enough to fit into a fist. Qin Hai knew that the concept of nanomaterials was more or less within the acceptable range of Cui Xuezhe, and this discussion of magnetic domains and coercivity had completely subverted the image of an ordinary young worker in Cui Xuezhe's mind. When will the young workers in a county know so many things, this is clear...... Is it good to talk about what you need to talk about when you defend your PhD?

"Brother!" Qin Shan was in a hurry, and Qin Hai showed it down again, but it was completely exposed. She had an idea, tugged at Qin Hai's shirt fiercely, and scolded: "Brother, did you read two articles from me yesterday, and today you recited them to bully Xuezhe?" You don't understand these things yourself, do you? ”

"Of course I don't understand, that's why I said it and asked Xiao Cui for guidance. Xiao Cui, I read that passage just now from a book by Xiao Shanna, and I memorized it because I thought it was funny, but I don't understand the meaning at all, can you explain it to me? Qin Hai said with a smile. Of course, he didn't say the above words when he was full of food and nothing, he wanted to use these contents to test Cui Xuezhe's knowledge and see if this doctor was an impostor.

Regarding Qin Hai's explanation, Cui Xuezhe could only be skeptical. The reason for the suspicion is naturally that he feels that Qin Hai memorizes such a passage is a bit unbelievable, this kind of academic judgment ordinary people will mispronounce books when they read them, how can there be someone like Qin Hai who memorizes them so well. As for the reason for believing, it is from Qin Hai's education and identity, if these words are not what Qin Hai sees from the book, then Qin Hai is simply a demon.

Of course, he couldn't imagine that Qin Hai was indeed a demon, and a big demon.

"The coercivity of a magnetic material is the external force required to change its magnetic properties. The paragraph that Brother Qin memorized just now is exactly what we are currently studying. We have measured that the coercivity of pure iron in the form of pure iron is only 20 to 100 ampere/meter, but when pure iron is made into ultrafine particles of about 16 nanometers, the coercivity can reach 80,000 amperes per meter, which has permanent magnet characteristics. We are trying to make smaller iron ultraparticles in the hope of obtaining new materials with stronger coercivity. Cui Xuezhe said to Qin Hai seriously as if discussing with his peers.

"Really? That's amazing. Qin Hai said with a haha.

At this moment, there was a sound of footsteps outside the door, Cui Xuezhe's eyes lit up, he got up and said, "My dad is here, I'll go and greet him." ”

Qin Hai and Qin Shan also stood up, Cui Xuezhe walked out of the room, and after a while, he led a middle-aged man in. With a shy smile on his face, he pointed to Qin Hai and Qin Shan and introduced to his father: "Dad, let me introduce you, this is Qin Shan, this is Qin Shan's elder brother......"

"It's you......" Cui Xuezhe's father looked at Qin Hai, he was stunned for a moment, raised his hand and pointed at Qin Hai, not knowing what to say.

Qin Hai stepped forward quickly, bowed slightly to Father Cui, and said, "Uncle, hello, my name is Qin Hai, I am a worker at Qingfeng Agricultural Machinery Factory in Anhe Province, I am very happy to meet you......"

As he spoke, he handed Father Cui a meaningful look, meaning that the other party must not be a goof.

"Anhe, Qingfeng Agricultural Machinery Factory, this ...... Oh, yes, yes, welcome, welcome Comrade Xiao Qin to Beijing. Father Cui is also a smart person, and he immediately understood Qin Hai's hint, but he was slightly stunned, so he accepted Qin Hai's self-introduction with a smile, and at the same time stretched out his hand and shook Qin Hai tightly.

Cui Xuezhe was really a nerd, standing aside, he didn't see Qin Hai and Qin Shan's expressions fluctuating at this moment, and he didn't understand the roll of the eyes that Qin Shan was flying towards him in a hurry. After making trouble for a long time, he was the only one in the room who was kept in the dark, because Qin Hai and Qin Shan both knew his father, and his father was also quite familiar with Qin Hai and Qin Shan.

This middle-aged man, whom Cui Xuezhe called an ordinary organ cadre, is Cui Hongchun, vice minister of agriculture. (To be continued) R580
