"The molecular dynamics simulation method has been developed relatively mature since the 60s, because the method is from the molecular atom motion simulation, describing the bond length, bond angle expansion and bending vibration, etc., until the molecule's rotation, displacement and other levels of motion behavior, the molecular vibration behavior reflected by the molecular vibration spectrum is also included in it....." Li He stood on the podium and talked endlessly, originally just wanting to deal with the translation and explain it for ten minutes on stage, but looking at the eyes of the class looking forward to him, perhaps because of the vanity left in his heart, he finally spoke for more than an hour unconsciously. Pen, fun, and www.biquge.info

Some unbelieving students said, "Is it really possible to calculate the vibrational spectrum?"

Li He said with a smile, "Of course, including the frequency of vibration and the intensity of vibration, the molecular force field used belongs to the category of classical mechanics, described by the empirical potential function of the atom, we will sort out some of the existing empirical potential functions for you, a total of 164, and give the applicable elements, as well as literature sources, I hope you have a little reference, these are the core elements of molecular dynamics, if you do this research in the future, you should understand." ”

"Little Lizi, how do you know?"

"These are all polymer physics, our school's science collection is still relatively small, I suggest you can go to the library in Huaqing to see, everything I know is from the library in Huaqing. For these curious babies, Li He can only deal with them like this, but fortunately, these are all basic physics, not the so-called advanced.

Li He had to lament the seriousness of the disconnection with foreign countries, and the disconnection of teaching materials due to information asymmetry, these theories had actually been developed in the sixties and seventies, but China had not been able to update the information in a timely manner.

Of course, the gap in basic physics will gradually narrow with the exchange with foreign countries, but the gap in applied physics cannot be changed in a day or two, and the establishment of each laboratory requires a huge amount of investment.

From a distance, I saw Su Ming standing on the flower bed smoking, Li He came out of the classroom, lit a cigarette by himself, spit out a smoke ring heavily, and asked, "Are you idle, what are you running around?"

"Brother, you are really good, I can't understand any of what you said on stage." Su Ming didn't understand these physical theories, but he felt very awesome.

Li He had no intention of showing off in front of Su Ming, it was no different from showing a blind man, and asked directly, "What's the matter, just say it, I'm going to eat in the cafeteria soon." ”

If you don't take advantage of the lack of people, it's not good to have a crowded canteen.

Su Ming saw that Li He was impatient, so he hurriedly finished speaking, and then asked, "Do you think this tape can be done?"

Li He said, "It's not that you can do it, but whether you dare to do it." Unlike when you practice a stall and become a self-employed person, if you are a tape factory, it involves the issue of employment, and you have to find a collective enterprise to be affiliated with, are you looking for it?"

In fact, more strictly speaking, it should be called a joint venture, where an individual cooperates with an enterprise belonging to the township street and registers it as a "collective enterprise" with the industrial and commercial department, but the township street must own shares.

According to the central government's "light industry by union" instructions, Shanghai and Changshu area set a precedent, the local policy has been introduced, there are a large number of private light industry enterprises, the most famous is the Shanghai Paper Industry Company and Changshu's garment workshop, and so on in 1985 Fei Xiaotong went to Changshu to inspect were startled, gave a "clothes are not the sky" inscription, praise the prosperity of Changshu garment industry.

In fact, the word affiliation arose in the late 80s and early 90s, and it itself contains the meaning of association, but the township streets can not own shares, and private individuals can wear a red hat as long as they pay a few thousand yuan.

On the one hand, it was because the finances of the township streets were generally tight, and on the other hand, because there were many restrictions on the development of private enterprises, and they needed to rely on them in order to bypass the gods and ghosts from all walks of life, which was related to the entire social environment at that time.

Later, when some private enterprises took off the hat of collective enterprises, they did have differences in the definition of property rights and assets, and there were many more troubles.

Li He is not afraid of this, piracy is at most more than ten years of golden period, and when the government begins to pay attention to copyright and intellectual property rights, it will become a street rat, hugging the grass and beating rabbits, and then whoever loves the empty shell will take it.

Su Ming smiled, "Brother, have you forgotten what my aunt is doing?"

"Forget it, just say it"

"The village director of Cui Gezhuang, don't say it's a relative, it's equivalent to giving them money for nothing, can they be happy?" Su Ming seemed to be confident, but said with a little difficulty, "Is that tape easy to do, this is high-tech."

Li He said, "What kind of high-tech dog, just have a recorder, a plastic plate, and a magnetic stripe." The key is that these things are not easy to buy, especially plastic plates and magnetic stripes, these are planned substances, there is no approval strip, where are you going?"

Su Ming immediately wilted, "I knew it wasn't that easy to ....."

"But..."

Su Ming immediately refreshed his spirits, "Brother, hurry up and say, but what?"

"It is to set up the factory in Shenzhen"

"Then let Yu Dehua's old boy get materials for us to Hong Kong?" Su Ming asked, he had also met Yu Dehua a few times, but he didn't like it very much.

Li He nodded with a smile, "If you set up in the capital, the cost of transportation will be high, and it will be difficult to form a scale." ”

"Brother, this is a business of millions a year.... You're going to think of a way to do it again?"

Li He shook his head, "Either give up, or go to Shenzhen, there is no other way, don't think about reversing the approval, that's not a long-term solution." ”

Li He hoped that Su Ming would go south, after all, Su Ming's limelight in the past two years was too great, and he couldn't hide from it if there was anything unnecessary.

Su Ming said, "Then I think about it, I'm leaving the capital, who cares about my business here.... I'll think again."

Li He didn't care about Su Ming anymore, seeing that class was about to end, he went to the cafeteria.

As soon as the bell rings, all the students will rush to the cafeteria, just to avoid waiting in line for a while, and if they are at the end of the line, they will have to wait at least more than 20 minutes before they can eat in the cafeteria.

Chen Shuo and the others saw Li He running away, and they also followed out.

If it is a self-study class, it will be skipped in advance.

When the National Day comes, the school gives three days off, although there is no statutory holiday, and the holiday is basically customary. Idle government agencies and units can come out on weekends and Sundays, and as for factories and mining enterprises, they can also take one day off a week or have compensatory or rotational holidays.

Although the school year has been less than a month, everyone has deeply felt the pressure, and they are too tired, and some students propose to go out for a trip.

As soon as this topic came out, the class exploded, some said to go to Zhongnanhai, some said to go to Xiangshan, and some said to go to Chengde.

Opinions could not be unified, and in the end they voted and unanimously decided to go to Xiangshan.

Zhao Yongqi crutches Li He with his arm, "Are you going?"

Before Li He could answer, Wang Hui, as the logistics housekeeper, came over to count the number of people, "Little Lizi, go or not, this is the last collective activity."

Li He thought about it, as if the time at home was a little long, and said directly, "I can't be separated from the masses, of course I go, I must go."
