Chinese entertainment for engineering students

"You have to miss me every day." At the entrance of the airport, Wang Fei hugged Wang Xu tightly, not wanting to separate for a moment, and tears seemed to flash in her eyes.

"Yes, yes, you have to miss me too. Be careful when filming. If someone harasses you, tell me." Wang Xu comforted softly.

"You have said many times that you will be careful." Wang Fei rubbed her head on Wang Xu's chest, took a long breath, and continued: "Remember your scent, you should also remember it. mine."

"Yes, I will." Wang Xu rubbed Wang Fei's hair, which was still smooth and soft.

"Let's go." Wang Fei let go of her hand, stood up on tiptoes, kissed Wang Xu gently on the lips, turned around and left, her steps firm, no longer as girlish as before.

Wang Xu watched Wang Fei and Sister Ying enter the terminal building, turned back to the roadside, put on his helmet, and left on his motorcycle.

The airport management is not that strict at the moment. Although some people may say that the airport will park it for a while, it will not be towed away immediately.

After a fast and furious journey, Wang Xu said goodbye to Wang Fei and returned to his busy daily life.

Although the semester has not yet started, Wang Xu still returned to the school for convenience. Living here is not that convenient, and the doctor's dormitory has not been divided yet.

There is no special spring class in Shuimu now. Wang Xu's graduation is not considered formal, and all procedures must be completed separately.

Fortunately, the department did not let Wang Xu run away on his own, and everything was taken care of by the department. Anyway, Wang Xu became the only doctoral student in the spring class, which can be regarded as a first.

In fact, Wang Xu now exists more as a question answering machine, but he also has his own focus, which is the verification of the growth method.

In his eyes, the fundamental method of growth is the foundation of everything that follows. Only by verifying it first can everything that follows become logical.

The growth method experiment was carried out in the Department of Materials, but a professor from the Department of Chemistry participated. This kind of vapor deposition equipment is not available now, but the design drawings given by Wang Xu are very detailed.

Especially the laboratory equipment itself is not complicated, and the processing is not difficult. Shuimu's school-run factory can handle it.

Don't underestimate Shuimu's school-run factory. This small-scale factory was very brilliant back then. Many of China's famous equipment were made here as verification models.

Although it is very depressed now, there are still many senior technicians above level six remaining. These people are the confidence and confidence that Mizuki can process many experimental devices.

This equipment is of course no exception. The main principle of the equipment is to maintain a combination of vacuum and high temperature, so there are certain requirements for processing accuracy, but it is not outrageous, so after working overtime, it took less than a week. , a vacuum vapor deposition equipment for laboratory use was completed.

Although it is laboratory equipment, the total weight of the equipment exceeds several tons, so the final assembly of the equipment was carried out in the laboratory that had been vacated in advance. The assembler is of course Wang Xu, who knows this thing best, and his skills are even more impressive.

Wang Xu actually didn't expect that this vapor deposition device had already caused a sensation in the Materials and Mechanical Departments before the experiment started.

The root cause of everything is not the deposition equipment itself, but the vacuum pump that evacuates. Since the current domestic vacuum pumps cannot meet the various parameter requirements of the vacuum chamber, Wang Xu had no choice but to draw a new one himself.

Even with the best CAD software available today, Wang Xu still stayed up late at night and drew for two days before completing the drawing of this pump. Fortunately, it was copied.

Damn software, it’s not smooth, could it be..., forget it, let’s do it one by one.

This thing comes from his maintenance skills. Vacuum pumps and pressure pumps are actually the same thing. Although the gadgets provided by the system are not more advanced than the products of the 21st century, they are somehow better than what China has now. grade.

Moreover, because Wang Xu copied the drawings, he also copied the gears in the vacuum pump and the refining method of the required steel. Regardless of whether it is shocking or not, single crystal copper has been released anyway, and there are not many more steels. Weird, right.

However, this refining method only has a general method, so several old professors from the Department of Materials studied it for several days, and finally succeeded in refining a new type of corrosion-resistant steel in the metallurgical laboratory.

In the early years, the Department of Materials had a metallurgical laboratory. However, in the early days of the founding of the People's Republic of China, when the departments were reorganized, professors, personnel and most of the equipment were supported, and the predecessor of the Imperial University of Science and Technology was established, the Institute of Iron and Steel Industry. .

Of course, the Institute of Steel not only accepts metal majors from Shuimu, but also some metal majors from other universities. Therefore, the Steel Institute has become a leader in China's metal profession, especially in the field of steelmaking.

However, the Department of Water and Wood Materials only has non-metallic materials laboratories and a small number of metal materials laboratories, so Wang Xu has to go to the school-run factory if he wants to find a metallurgical laboratory.

However, Mizuki later gradually rebuilt majors such as metal laboratories and metal metallurgy, mainly engaged in edge cutting-edge research such as powder metallurgy, and rarely involved in steelmaking and the like.

At that time, the major adjustment of departments involved almost all the established universities in China. You can see the shadow of Shuimu in many now famous universities. For example, Beihang University was formed by merging the aircraft major of Shuimu and the aircraft major of other schools. .

The University of Geosciences was mainly composed of the Department of Geology of Imperial University, plus the geology departments of some other universities, and even some teachers from the Mizuki Electronics Department were merged to become the electronic major of Imperial University.

Anyway, at that time, almost all the eight major colleges on Imperial College Road were established in this way. Later, when many universities in China were established, they would allocate resources from these old and famous universities to support them. This was a very common phenomenon in that era.

However, in this life, because Wang Xu developed single crystal copper, the call for rebuilding the metal profession, and even the metallurgical profession, was raised. Metallurgy is not without cutting-edge topics.

For example, powder metallurgy is a part of Wang Xu's project this time, because his speakers urgently need the support of strong magnets.

Anyway, the materials department has been messed up by him, so it won't hurt to mess up a little more.

This time, to make steel, Shuimu really didn't have the equipment. But this is not a problem. Shuimu does not have it. The steel yard built with assistance back then does. It is only a few bus stops away from Shuimu.

Therefore, even after decades, there are still many connections between the two schools. The ideas given by Wang Xu were handed over to an old professor with whom I had a good relationship and asked him to arrange experiments, so that the Department of Materials could feel free to do other things.

As a result, a disciple of the old professor at the Steel Institute took over the project, and using the ideas given by Wang Xu, he quickly developed this kind of corrosion-resistant steel, which was then subjected to a series of heat treatment processes as explained in the instructions. after.

The disciple was surprised to find that the various parameters of this thing were ridiculously good, not to mention wear resistance and corrosion resistance, and it also had excellent tensile yield strength, which is considered top-notch among alloy steels. This TM Isn't it just excellent ship steel?

Then, of course, the metallurgical profession there exploded. Many people came to watch this major achievement, and various tests were carried out quickly.

You know, although the Steel Institute is not a national defense academy, metallurgy is a heavy industry, and almost all equipment in the military is inseparable from the improvement of the performance of metallurgical materials. So, there are always permanent military representatives here, um, so ha, soon, people in white military uniforms also arrived.

Then there are various sampling, strength tests, wear resistance tests, performance tests, acid and alkali tests, salt resistance tests, high and low temperature tests, which are carried out in laboratories of different institutions.

Of course, repeated tests are inevitable, and they were carried out more than once in the Steel Institute.

Then, people in green military uniforms and blue military uniforms came, and the above description unfolded again.

Don't think they are wasting. It is irresponsible not to test the results in your own laboratory. Testing a sample in multiple laboratories and referencing each other is the prerequisite for the final determination of material performance.

Anyway, in this Steel Academy, which has just celebrated the New Year and is still filled with a festive atmosphere, there are countless people who are too busy to go home.

Not to mention the excitement at the Steel Institute, the Materials Department was also a little stunned when they got the results and finished products.

But we still immediately used this batch of steel to process and produce the needed vacuum pumps, because the teachers from the Mechanical Department were still waiting.

Therefore, when the vacuum pump that only existed on the drawings was actually manufactured, a professor from the Department of Mechanical Engineering stared at the finished product for a long time.

This is a small pump the size of a handheld radio, compact, delicate and compact.

Since it has just been manufactured and the outer shell has not been painted yet, it looks shiny and pretty. It has a unique industrial beauty.

But obviously, that is not what the professor from the Department of Mechanical Engineering looks at. He has seen too much industrial beauty, not least of which is this one.

Mainly, he was thinking, if this thing was slightly modified, the air inlet and outlet were reversed, and a can was added there, and if the refrigerant was sent in instead of air, wouldn't it be a compressor?

You must know that the structure of the compressor is not complicated. The complexity lies in the materials and processing. It’s not that there are no compressors produced in China, but the compressors produced in China are large, noisy and have a short lifespan.

But the thing in front of me is small and compact enough, and the material it uses is highly corrosion-resistant and wear-resistant, so is that okay...

Do you know how many refrigerators and air-conditioning compressors China imports every year? Do you know how many imported refrigerator and air-conditioning production lines have been shut down because they cannot import compressors due to lack of foreign exchange.

The teacher of the Department of Mechanical Engineering felt as if a large piece of gold had fallen on his head, and his eyes were filled with stars. He felt that it might not be just him, but many people would be unable to sleep because of this.
