Chinese entertainment for engineering students
Chapter 121 Electron Microscope (1)
"What are you doing here if you don't sleep at night?" The dormitory manager, Uncle Zheng, was startled when he saw the flashing cigarette butts, and he lit up the street lights in the dormitory with his voice.
This voice-activated lamp is said to be the graduation project of a senior in the department two years ago. It is considered the first of its kind in China. It has been available abroad for a long time, but it has been blank in China. This senior made a sample, and the effect is actually quite good.
It is said that a factory has started production, and a senior has been hired as a technical director. The department has also promoted it for a while, which is regarded as a highlight of industry-university-research.
"Uncle, it's you, have a cigarette." When Wang Xu saw his uncle getting up, he reached out and handed over a Hongtashan.
"You kid, go to bed early. You'll be late when you come back. If you don't sleep, you won't be able to go to class tomorrow. Oh, by the way, I don't think you have to go to class." The uncle took it with a smile, came over and lit it with a fire, holding a cigarette in his mouth. , pulling on his slippers and walking to the toilet.
Wang Xu watched the dormitory uncle leave and went back to bed himself. Wang Xu was moved to the upper bunk near the door. The bed here was actually very unfriendly to Wang Xu. He felt curled up while sleeping, which was far less comfortable than the modified bed at home.
But who made Wang Xu especially afraid of loneliness after getting along with Wang Fei? The old driver actually became popular. Rather than being a proper tool like in other worlds, lifeless.
This is a good sign. Wang Xu used to suspect that he would completely sink into silence in no matter which world he was in. Maybe this world would be Wang Xu's end.
The life and death of a time traveler does not depend on the body, but on the soul. The death of the soul is more terrifying than anything else. Wang Xu is very grateful to the world and the woman who brought him popularity.
In three days, Wang Fei will be back, and Wang Xu secretly counts the days until they can meet again. As for tomorrow, oh, no, it’s today, the day when the experiment starts. I have to go there and follow it. I finally have the opportunity to face high-end equipment directly. Wang Xu is not going to give up.
A few hours of sleep was actually not very good, but Wang Xu still woke up early.
Get up, do boxing, and buy breakfast. Wang Xu bought the breakfast in the dormitory recently. Who makes him get up the earliest every day. Seeing that he went to bed the latest and got up the earliest every day, the brothers in the dormitory were all amazed and asked about Wang Xu's secret method.
Several brothers have learned a set of different boxing techniques from Wang Xu, but after a month, only Dadong is still getting up early to practice, and the others can't sleep well practicing boxing.
This set of boxing can still play a role in strengthening the body and flexing the limbs. At least it is not worse than Bagua Tai Chi. The disadvantage is that it has no practical effect. The boxing movements are wide open and closed, the fighting is vigorous, the shape is majestic, and it is very beautiful. Dadong learned it because of this.
There were five lunch boxes in a net bag. When Wang Xu strolled back to the dormitory, several brothers had also gotten up and were lining up to wash up in the water room.
At this time, dormitories still had public water rooms and bathrooms, and you had to queue up when you got up early and went to bed late.
The most troublesome thing is when a friend of the opposite sex comes to visit. If you want to go to the toilet, you have to follow that person. Wait until the toilet is empty, then let the friend in, and then guard the door. Every time I see this, other students are envious and amused.
What I envy is that he has a girlfriend, but what’s funny is that guarding the toilet for his girlfriend is not considered decent.
Why don't you lock the cubicle? Well, not many toilets have doors these days. Even if they do, they will be almost broken within a few years. You don't need to talk loudly to each other.
"Brother Zhang, you're early enough. Have you eaten?" When Wang Xu rushed to the scanning electron microscope laboratory, it was not yet eight o'clock. Zhang Hongyu, his Ph.D. brother, had already arrived and was opening the door.
"You've eaten, you're early enough." Senior Brother Zhang replied politely. He had already had several contacts with this junior brother, and they were no strangers to each other.
Moreover, his teacher, Professor Duan, also reminded him not to treat this junior fellow student like an ordinary undergraduate. He is a very mature person, and he is particularly capable of tossing.
There is actually quite a lot of gossip in the academic circle. Although it is not as blatant as in the entertainment circle, there is no shortage of people watching the fun, not to mention the academic circle which seriously lacks entertainment life.
Therefore, Wang Xu's story has long been spread throughout the Department of Materials. After all, it is rare to see an undergraduate who has worked on a very important project, not to mention he is tall and handsome.
Zhang Hongyu is quite tall, at least 1.8 meters. He is from Zaozhuang, Qilu. He has stayed in the imperial capital for seven or eight years, but he still has not changed his local accent. The first thing anyone who comes into contact with him would do is ask where he is from.
It can be said that he made great contributions to promoting the name and dialect of his hometown in Shuimu.
Fortunately, Qi Lu's words are not easy to mislead others. At least Wang Xu didn't see the senior brother who called the chat "Lagua", but there were quite a few who said "What are you looking at?"
Today's experiment actually has nothing to do with Wang Xu. All operations are handled by Senior Brother Zhang. Professor Duan will come over soon. This equipment is still very new and very expensive. Professor Duan can't get it right, even if it has been operated many times. Senior Brother Zhang is not at ease.
In fact, Professor Duan is still very young, in his forties and thirties, and looks very energetic.
He is an undergraduate at the Imperial University next door and went abroad at his own expense in 1988. He must have been one of the first batch of students to go abroad at his own expense. He studied for a Ph.D. at the Massachusetts Institute of Technology, and he got the degree in three years by relying solely on scholarships and washing dishes.
I stayed overseas for four years, published several review journals, and won the Young Scientist Award from some association in an ugly country. My resume is very impressive, but my detailed achievements are only mediocre. I only officially joined the position at the beginning of last year. The department directly gave me the title of associate professor and was responsible for setting up the condensed matter laboratory. It was considered a special treatment for recruiting talents.
Professor Duan attached great importance to Wang Xu's experiment. After Wang Xu's lecture, he went back to search and think very carefully. He thought that this direction was really promising, even if it was just to determine the thickness limit of flake graphite. I can publish a good SCI article.
By the way, the assessment pressure on lecturers and professors is not that great at the moment. There should not be too many lecturers and professors who make a living by translating foreign papers. But this is also inevitable. One is the gap in talents, and the other is the gap in technology. During that special period, it was not just novel writers who were harmed.
Since the reform, it can be said that the entire academic community has been busy looking for ways to make up for it. Translating papers is one of the important projects. At this time, the English level of undergraduates is not enough to read foreign papers fluently.
Wang Xu helped Senior Brother Zhang clean the outside of the laboratory first. Unlike later eras when scanning electron microscopy was almost universal, current scanning electron microscopy equipment is placed in clean rooms.
The entire laboratory has three parts. The outermost changing room is connected to the outside world. There is a ventilation channel in the middle, and then you enter the clean room, where you can see the equipment.
There are full-time equipment maintenance personnel here, but they are inside for a long time, and the cleaning of the outside is directly done by the students who come to the experiment.
What Wang Xu and the others were cleaning was the outer room, the room where people changed clothes. As for the inside, it needs specialized personnel to clean it every time, and the sweepers all start with master's degrees.
Either way, the laboratories at that time were more troublesome. Didn't you see that even the radio laboratory required a special anti-static floor, and you had to change clothes and slippers when entering and exiting?
