Huayu for engineering students

Chapter 121 Electron Microscope ([-])

"You don't sleep at night, what are you doing here?" The uncle of the dormitory manager was startled when he saw the flickering cigarette butts, and turned on all the street lights in the dormitory with a loud voice.

This voice-activated lamp is said to be the graduation project of a senior in the department two years ago. It is considered to be the first of its kind in China. It has existed abroad for a long time, but it has been blank in China. This senior made a sample, and the effect is not bad.

It is said that there is already a factory for production, and the senior is also hired as a technical guide. The department has also publicized it for a while, which is a highlight of the industry-university-research institute.

"Uncle, it's you, smoke a cigarette." Seeing that the uncle got up, Wang Xu stretched out his hand and handed him a Red Tashan.

"You boy, go to bed early, you will come back late, you still don't sleep, and you won't have class tomorrow. Oh, by the way, it seems that you don't have to go to class." The uncle took it with a smile, leaned over to light the fire, and held a cigarette , pulling the slippers and walking towards the toilet.

Wang Xu watched the uncle in charge leave, and went back to bed by himself.Wang Xu was moved to the upper bunk next to the door. The bed here was actually very unfriendly to Wang Xu, and he felt curled up when he slept, which was far less comfortable than the reformed bed at home.

But who made Wang Xu feel particularly afraid of being lonely since he got back with Wang Fei? The old driver actually gained popularity.Instead of being a proper tool man like in other worlds, he is lifeless.

This is a good sign. Wang Xu used to suspect that he would completely sink into silence if he didn't know which world he was in. Maybe this world was the end of Wang Xu.

The life and death of a traveler is not based on the body, but on the soul, and the death of the soul is more terrifying than anything else.Wang Xu is very grateful to this world, and also to the woman who brought him popularity.

In three days, Wang Fei will be back, and Wang Xu is secretly counting the days of reunion.As for tomorrow, oh, no, it's today, the day when the experiment starts, so I have to go and follow it anyway. Finally, I have a chance to face high-end equipment, and Wang Xu doesn't intend to give up.

A few hours of sleep is not really good, but Wang Xu still woke up early.

Get up, fight, buy breakfast, the breakfast in the dormitory is bought by Wang Xu recently, who made him get up the earliest every day.Seeing that he sleeps the latest and wakes up the earliest every day, the brothers in the dormitory are all amazed, and they have also inquired about Wang Xu's secret method.

The brothers have all learned a set of boxing with four different styles from Wang Xu, but after a month, only Dadong is still waking up early to practice, and the others, how can they sleep well after practicing boxing.

This boxing method can still strengthen the body and flex the limbs, at least it is no worse than Bagua Tai Chi, the disadvantage is that it has no actual combat effect.The boxing moves are wide open and close, and the fight is vigorous, the shape is majestic, and it is very beautiful. Dadong learned it because of this.

A net bag, containing five lunch boxes. When Wang Xu strolled back to the dormitory, several brothers also got up and were lining up to wash in the water room.

At present, the dormitories still have public water rooms and bathrooms, and they have to queue up when they get up early and go to bed late.

The most troublesome thing is when friends of the opposite sex are guests. If you want to go to the toilet, you can only follow someone else. After the toilet is emptied, let your friends go in, and then guard the door.Every time I see this, the other students are both envious and funny.

What I envy is that someone has a girlfriend, and the funny thing is that it is really not decent to guard the toilet for the girlfriend.

Why don't you lock the cubicles? Well, not many toilets have doors these days, and even if there are, it's almost broken in a few years, and you don't need to chat loudly with each other.

"Brother Zhang, you are early enough, have you eaten yet?" When Wang Xu arrived at the scanning electron microscope laboratory, it was not yet eight o'clock, and the doctoral brother Zhang Hongyu had already arrived and was opening the door.

"I've eaten, and you're early enough." Brother Zhang replied politely. He had already had contact with this little brother several times, and they were no strangers to each other.

And his teacher, Professor Duan, also reminded him not to treat this junior with the attitude of ordinary undergraduates, he is a very mature person, and he is especially able to make troubles.

The trend of gossip in the academic circle is actually not small. Although it is not as blatant as the entertainment circle, there is no shortage of people watching the excitement, let alone the academic circle that seriously lacks entertainment life.

Therefore, Wang Xu's story has long been spread in the Department of Materials Science and Technology. After all, it is really rare for an undergraduate to toss a very important project, not to mention that he is tall and handsome.

Zhang Hongyu is quite tall, at least 1.8 meters. He is from Zaozhuang, Qilu. He has been in the imperial capital for seven or eight years, but he still does not change his accent.So that every person who just came into contact with him, the first sentence is to ask where he is from.

It can be said that he has made great contributions to promoting the name and dialect of his hometown in Shuimu.

But fortunately, Qilu dialect is not easy to mislead others, at least Wang Xu didn't see the brother who called the chat "lagua", but there were quite a lot of "what are you looking at".

In today's experiment, there is nothing wrong with Wang Xu. Brother Zhang is responsible for all the operations. Professor Duan will come over in a while. This equipment is still very new and expensive. Professor Duan is very precious, 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 40s and 30s, he looks very energetic.

He is an undergraduate from the Imperial University next door, and went abroad at his own expense in the [-]s.He should be one of the first batch of students who went abroad at their own expense. He studied for a Ph.D. from the Massachusetts Institute of Technology in an ugly country. He got his degree in three years thanks to scholarships and cleaning dishes.

After staying overseas for four years, he has published several core journals, and won a young scientist award from an ugly country association. His resume is very prominent, but his achievements are mediocre.He officially joined the job at the beginning of last year, and the department directly gave him the title of associate professor, responsible for setting up the condensed matter laboratory, which is considered a special preferential treatment for recruiting talents.

Professor Duan attached great importance to Wang Xu's experiment. After Wang Xu's lecture, he went back and searched and thought very carefully. He thought that this direction was really interesting. Even if it was just to determine the thickness limit of flake graphite, A good SCI can be published.

By the way, the assessment pressure of lecturers and professors is not too much at the moment, and there should not be too many lecturers and professors who rely on translating foreign papers to dawdle.But this is also inevitable. One is the fault of talents, and the other is the fault of technology. The scourge of that special time is not only for novel writers.

Since the re-opening, it can be said that the entire academic world is busy looking for supplements. Translating papers is one of the important projects. At the moment, 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 the era when scanning electron microscopes were almost universal in later generations, the current scanning electron microscope equipment is placed in a clean room.

The entire laboratory has three parts. The outermost changing room is connected to the outside world, and there is a passage for blowing air in the middle before entering the clean room, where the equipment can be seen.

There are full-time equipment maintenance personnel here, but they stay inside for a long time, and the cleaning of the outside part is directly done by the students who come to the experiment.

What Wang Xu and the others cleaned was the outer room, the room where the clothes were changed.As for the inside, special personnel are needed to clean it every time, and those who sweep the floor are masters.

Or how can I say that the laboratory at that time was 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 you entered and exited.
