Chinese entertainment for engineering students

Seeing Tang Yun regaining her energy and rushing towards the tailor shop, Wang Xu smiled happily.

Wang Jinghua watched with cold eyes. She had experienced this little man's painting skills before. Isn't he just doing his job here and still enjoying it? Wang Jinghua’s husband said more than once that she had been brainwashed, but she could not utter a word to refute.

It was indeed brainwashing. That little man was so good at deceiving him. He made his blood boil with just a few words. He agreed on the same day and joined the job two days later. It was as if he had been demoted.

But the benefits are real. Not to mention wages and bonuses, it’s hard to pay them yet, but daily meals are basically free of charge.

Although Wang Xu hasn't come back yet, this small recording studio has already spread among major record companies just by virtue of the reputation of recording two singles.

There was an endless stream of colleagues coming to visit, but it never stopped. In just ten days, her business card folder was almost full.

Wang Jinghua's name is no longer completely unknown. Even the last time she went to Yangyin to contact for cooperation, the department chair there had heard of her name. A world-class recording studio, this is the evaluation given by the professionals who have been here.

The only drawback is that it is too small and can only accommodate a 5-member band. Otherwise, recording symphonies and piano music is where a recording studio of this level should play its role.

She has received recording cooperation invitations from several record companies. Although they have not been finalized yet, they are really promising in the future.

Thinking that the blueprint Wang Xu drew for her is being realized step by step, and the promise to her is becoming reality step by step, Wang Jinghua can say that she loves and hates this little boss.

Wang Jinghua rented the top-of-the-line Shanshui speakers in the living room from a friend. Wang Xu, a paranoid man, was unwilling to buy the set of speakers and had to wait until she came back from Xiangjiang to get them herself, so she had to take this step. .

But the recording studio that this paranoid man built by himself has become the best in the industry and the best in the world. At first Wang Jinghua didn't believe it, but after several experts from Central Music listened to the single they recorded, they couldn't stop praising it, which made Wang Jinghua completely relieved.

This little boss can let go of everything, but when it comes to equipment, he is simply not willing to make do with it. Wang Jinghua couldn't help but secretly curse Wang Xu, but she didn't know that this was actually the result of Wang Xu's improvisation.

No matter how much Wang Jinghua complained, she actually maintained a lot of respect for this little boss. Although his career seemed to be uneven, almost every one of his achievements had reached a peak that others could not reach in their lifetime.

Such a god cannot be overestimated in any way, not to mention that the conditions given by Wang Xu can be said to be very rare. After all, even if a general manager is hired in this era, it is usually based on a salary plus bonus model, with at most a performance commission.

It can be said that there is no one like Wang Xu who directly gives options. Even in the ugly country, this model has not yet become popular. It was not until Internet companies became popular that options became the standard for new companies.

Wang Xu didn't know or care about Wang Jinghua's slander, because he had already planned to go back to school and his next step of work needed to start.

It was still early, and Wang Xu didn't plan to have lunch with Wang Jinghua. Riding on the long-lost motorcycle, Wang Xu felt really eager to reunite with his old lover. Accompanied by the familiar roar of the engine, Wang Xu sped towards Mizuki.

His next important experiment was also to develop technology from microphones, but that technology was too high-end and he couldn't take it out directly, but after analyzing the data in detail.

He knew that a good opportunity was in front of him again. This should be a piece of research that could establish his scientific research status. At the same time, it is also a piece of research that many academic masters and senior time travelers like to plagiarize, tearing off tape.

Smart readers may have already guessed that, yes, the thing Wang Xu wants to work on is graphene. To be honest, he had long forgotten that there was such a big leak to pick up now.

This is really a necessary skill for the protagonist of a time-traveling novel ten years ago, but it is a pity that it was abandoned by the younger generations of time-travelling. It is too simple and there is no challenge.

Wang Xu is not afraid of simplicity. It is only 1991, and the two real discoverers should still be in middle school, so there is no problem in terms of time. But the problem is, who said peeling off tape is easy.

It is not difficult to tear off the tape. Just stick the pure graphite sheets on both sides of the 3M tape and then tear it off.

Wang Xusheng was afraid of buying fake tapes in the Imperial Capital, so he brought back a lot of them from Xiangjiang. He complained in his mind that counterfeit goods were now so rampant in the Imperial Capital that it was almost impossible to guard against them.

The difficulty is how to make sure that what you tear out is thin enough, because graphene is transparent, almost completely transparent, and its light transmittance can reach close to 98%.

Readers may not be very familiar with this data. You only need to know that the light transmittance of ordinary lighting glass is about 80%, and the top-grade leaded optical glass can achieve about 95% with a transparent film.

Such a high light transmittance means that visible light will pass directly through this thin material and shine directly on the tape, making it impossible for you to distinguish it.

Moreover, all graphite is not in an ideal state. It is not just plain and pasted on a layer of graphite, but mixed together at various angles and directions. The process of tearing will also squeeze and stack the edges of the material, creating a more chaotic situation.

The two doctoral students in the previous life watched the scanning electron microscope and observed continuously for several months before they were able to finally find a single graphene layer with a diameter of only 500 nanometers among thousands of photos, finally proving that graphene is exist.

And how much does it cost to take a photo with a scanning electron microscope? Sorry, it’s almost 1,000 yuan. Fortunately, Mizuki's scanning electron microscope is quite new and is fully digital. You can view the shooting results directly on the computer without having to develop the photos like before.

But Wang Xu is a student. He can't occupy the electron microscope for a long time. It's a big deal if he can use it for two days.

So he had to find a way to increase the probability of hitting, which meant that he had to determine as much as possible that there was a single layer of graphene on the sample and its approximate location before sending the sample to be photographed.

Wang Xu's physical perception is very good, but it is not as good as the nanometer level. However, his naked eyes can distinguish the intensity of light and can indeed detect less than 1% change in light transmittance.

Therefore, based on the extremely small changes in light transmittance, Wang Xu can indeed roughly determine which area has a higher probability of having a single layer of graphene, thereby ultimately increasing the hit probability. The disadvantage is that it is more troublesome.
