31 Chapter 31: A False Alarm

October 8th, Sunday.

After ample rest and a lazy sleep, Cheng Yongxing and You Tianzhan came to the laboratory together after 10 o'clock.

It may be Niu Pin’s account, or it may have been just after school. He has been guarding this experimental platform these days and doing experiments quietly, without any interruption.

You need to face reality and cannot escape.

He also encountered the phenomenon of inconsistent test data in his work, such as when testing radio signals.This phenomenon is often caused by poor contact.

The installation of optical fiber is still very complicated.Unlike telephone lines and network cables, it can be plug and play.Even for later generations, the installation of optical fibers requires qualified personnel to operate.

Now, the related equipment is outdated, the operation is inconvenient, the quality of various components is relatively poor, and the requirements for the operators are even higher.

"Then what should I do now, where can I find someone who can install optical fibers?"

Youtian Zhan has never experienced such a thing.

"No way. Fortunately, our design is actually very small. There are not a few nodes in total. Try a few more times and test as you go. First follow the standard steps. If it works, you can verify it."

The installation and connection of optical fiber are described in standardized procedures. They can always do it according to the gourd drawing.

Turn on the power, and then test.Reconnect nodes one by one.Two people are cautious and try to follow the operating steps as much as possible.

Which node caused the largest shift in the result when shaking, they took it apart and redo it.

Neither of them has undergone formal training, and now they are completely hitting the Grand Canal!So the whole process was not smooth sailing.After some nodes were redone, the effect was even worse!

Only redo it repeatedly until the effect improves.

Cheng Yongxing participated in some electronic experiments, but at that time, there was a dedicated operator, operator, in the laboratory. If you tell him what to do, he will do it for you.

These people are specially trained.The advantage is to save the researcher's time and avoid the loss caused by the researcher's operation error.But the disadvantage is that researchers can't walk without the environment.

No choice but to bite the bullet and solve the problem.Fortunately, the results were good. After several adjustments to a node, the test data showed obvious improvement, which gave everyone a lot of confidence.

"Let's do it, maybe you can replace one more, not every node needs to be replaced."

Cheng Yongxing did a fine operation for a while and was a little upset.

He is not a very patient person, this kind of impatient, more from the psychological and physical, even if it is rebirth, it will not help much.

This is also one of the reasons why he caught Youtian Zhan.This kind of boring labor is what he dislikes the most!Youtian Zhan didn't complain, didn't fight, and just stretched out his hand. Maybe this kind of experience is still very novel.

Soon, after replacing the two interfaces, the data finally stabilized!

It's not easy, a false alarm!

Many things, in the final analysis, are psychological effects.

The root cause is that Cheng Yongxing has doubts about the current world in his heart!Doubt whether this world is real!

————————————————

Since the output data has shown considerable consistency, there is no need to change the remaining nodes.If you change it again, it will be self-defeating!

The experimental conditions are basically ready.

Time flies, and it's 5 o'clock in a blink of an eye.Two people spent a whole day in this small room!

"Stop doing it, tired."

Repeated work, even Youtian Zhan has some irritability.The constant rework itself is very morale hurt!

"Eat first! Go back to rest after eating, and come back tomorrow afternoon."

"Okay, let's go, I don't know if there are many people going now."

Usually this point is when there are most people.

"No, today Sunday, the time period when people come to eat will be more scattered."

Cheng Yongxing had already suspected the connection problem yesterday, but he was not very confident, especially those instruments had not been used.

In addition, he is still carefully adapting and inspecting the world.Fortunately, the operating rules of the world have not changed, and the physical rules are the same.

————————————————

The two of them had been engaged for a day, and both felt a little irritable, but at least it was better than yesterday.

The window master at the National University of Technology was very interesting. He bought two two liang and gave more than six liang.

Cheng Yongxing was in a good mood, so he went to take advantage of it. He made two or two first, and then bought two or two after half of the meal. This saved the two-two meal ticket.

This technique of taking advantage of this made You Tian Zhan stunned.

But this way, there are too many people to use, because you have to line up twice.And when I come back after the meal, there are no seats if I can't fix it.

There is also a good thing in the canteen of the Gongda, pickles, which cost two cents, which is very cheap.In the Northeast people’s impression, pickled vegetables are not considered vegetables, so everyone buys them only for breakfast.

Pickles are a good dish to kill time. Cheng Yongxing simply bought two pickles, put them on the table and tasted them slowly.If there is a little alcohol, it will be fine.

It's a pity that the environment of the canteen is filled with people and there is no atmosphere at all.

————————————————

On Monday afternoon, Cheng Yongxing went to continue the experiment after class.Everything is the same as leaving yesterday, all data are very stable.The environment for the optical fiber part was set up, and things finally got on the right track and went smoothly.

"It's so smooth, I should go to dinner after finishing yesterday, so I don't have to worry about it all night..."

Youtian Zhan also ran over after class, and arrived earlier than Cheng Yongxing.

"Not necessarily! If we continue to do it yesterday, we may not have good results! Both of us were a little impetuous yesterday. In that situation, everything is prone to error. Today seems to be going well, and it has something to do with our calm mood. "

The next focus is to enter the real measurement and verification.

The experiment designed by Cheng Yongxing uses a sophisticated mechanical device to convert the detected quantity into the bending of the optical fiber, which is then reflected by the change in the intensity of the optical fiber.They spent a few days setting up the fiber optic environment last week, and they can begin to verify the relationship between the detection volume and the change in light intensity.

The design of this agency, in a strict sense, is more like a patent for a new type of sensor, a product rather than a theory.But many experiments in engineering are like this, and theoretical inventions have little to do with engineering.

When he chose a few topics, he also took into account the difficulty of manufacturing the structure of the organ, at least not to use too complicated shapes, using wood, iron sheets, and springs, simple ones can be built.For these things, Cheng Yongxing is still confident that they can be combined by hand.

Once the mechanism is completed, it is the real turn to test.

It's really the test data step, but it takes the least time.

The structures of these projects are relatively common in later generations, and they are relatively secure, and the success rate should be relatively high.

Sure enough, although the test data is somewhat biased, the theory is correct.

The deviation of the data structure is mainly caused by the structural size of the conversion device, the manufacturing precision is not high, inaccurate, and the springs and other components do not match the nominal ones.But these no longer affect the proof of the theory.

It took a few days to continuously optimize this simple conversion device. By Thursday, there was no conceptual problem.

The two divided their work again.Youtian Zhan went to prepare for the next experiment, while Cheng Yongxing was about to write a thesis.He needs to show it to Professor Wang for review on Sunday.

Although there are only two days left, fortunately, he can take time to copy things during the day.This makes his effective time much higher than during military training.

To prepare a complete thesis, there are a lot of things to do, just a dozen diagrams.Because the data has shifted from what was expected, everything must be redrawn.

The era of writing with a pen and drawing pictures with a pen really tests people's patience.This is just a draft, it does not require high cleanliness, even if there are occasional mistakes, just smear it.

If it is an official document, his font cannot be shot.

After two days, Cheng Yongxing finally got the files out.On the other side, Youtian Zhan’s data has also been collected.

In the past few days, Cheng Yongxing discovered that You Tianzhan was much better than himself in doing specific things.It makes sense that character determines fate.

Youtian Zhan has decades of experience less than himself, but he has a clear-cut approach in doing things. Cheng Yongxing trusts his data and conclusions more than his own.

If he hadn't taken advantage of information and experimented at the same time, he might have lost to You Tianzhan.This conclusion shocked him.

————————————————

It has been more than six weeks since the rebirth, Cheng Yongxing has slowly got used to the new living environment.Even in the room of eight people, he can quickly fall asleep.Human adaptability is huge.

But this is just his own perception.

Although his body is a young man, his memory makes some of his speech and behavior, including his walking posture, bear the mark of later middle-aged people.

For example, during military training, he eats more tenderly, less than girls, and loves cleanliness so much. Sometimes his classmates make fun of him.

No one has heard of such things as GAY. Adjectives such as sissy, little girl can be regarded as out-and-out derogatory terms.This kind of treatment was a phenomenon he had not encountered in his previous life, but fortunately, he was not really problematic.Ignore it, and soon no one mentioned this small trend.

Cheng Yongxing has been running the laboratory for almost a week.The classmates were aware of it, but no one asked, everyone was still carefully exploring this novel world.
