Chapter 1064: If you have cheated, you should use it appropriately
The samples on hand do not even need to be subjected to physical and chemical inspection by equipment, they can be easily distinguished. This stuff is even comparable to the layers of coal ash in the chimney.

What is chemical vapor deposition? This thing looks more like physical deposition - coal ash piled together, and has nothing to do with the gas phase.

"Can you find the reason? Or do you think chemical vapor deposition can produce pyrolytic graphite?" Old Duan looked at this thing, and even his confidence in Gao Zhendong began to waver.

"It's hard for me to say now. I'm still exploring the theoretical knowledge of CVD, and it's not within the scope of my previous research. But in theory, it is indeed a way, but." Yu Yuncheng sighed. Compared with Chief Engineer Gao, he is still far behind.

"This is not a solution. We have to think of a solution." Old Duan touched his chin.

Yu Yuncheng said what he wanted to say but couldn't: "Should we ask Chief Engineer Gao?"

"Oh! Yes, this method should work. We can try it regardless of whether there are any dates or not." Old Duan's acting skills are at their best now. In fact, in his heart, he estimates that there may be more dates over there than here, but he can't show it too obviously.

Yu Yuncheng nodded repeatedly: "Well, I want to do CVD. In fact, it was Chief Engineer Gao who first inspired me. Let's go find him and see if he has any ideas in this regard. I guess he does, otherwise he wouldn't have inspired me."

Yu Yuncheng was completely unaware of Lao Duan's acting skills, mainly because the gap between him and the person he was talking about was too big to have any other ideas. As for Gao Zhendong, he was completely convinced.

If it weren't for Gao Zhendong, he would have some confidence that he could produce high-purity single crystal silicon by now, but he wouldn't dare to think about producing single crystal silicon for commercialization, or even making a special single crystal furnace.

Two groups of comrades from the Northeast simultaneously considered going to Beijing for advice, but their progress was different.

Because everything went smoothly for Chai Gong from Dongguan Institute, with solid results and everything available, he went to Beijing very quickly. He only needed to take the results he had summarized.

But for the comrades at Dongtan Institute, it is not that simple. Their main job is to sum up lessons, which is troublesome and takes much longer.

It is said that failure is the mother of success, but they not only have the mother of success, but also the grandmother and great-grandmother...

The woodcutter who arrived in the capital first found Gao Zhendong calmly and familiarly this time.

"Chief Engineer Gao, I'm here again." Seeing Gao Zhendong, Engineer Chai's face was filled with smiles.

It's still early days for making practical long-distance communications optical fiber, but at least for now, he knows he's on the right track.

"How's the situation? It's going quite fast, haha." Gao Zhendong said with a smile.

"The situation is very good. We have achieved results in the several tasks you arranged. As for the speed, it is mainly because of the good cooperation among comrades, and the institute is also very supportive of my work."

This is not something that a woodworker can handle alone. It requires the work of a large group. Otherwise, just burning the glass will make him sick.

He could only do sequential operations over and over again by himself. With two comrades assigned to him by Dongguan Institute, he could make glass, do tests, and conduct analysis and research, and get the entire production line running.

Engineer Chai handed the results he brought to Gao Zhendong. Gao Zhendong read them and was very happy and praised them highly.

As long as comrades have a direction, they can get things done very quickly, especially for a topic that is of a startup nature. With their own efforts, the speed is simply amazing. For a startup, there are not such high requirements, so it is easier to produce results.

"…the local fluctuation of material density is 1 dB/km, and the scattering of grain defects under current technical conditions, the loss of fused silica glass at a wavelength of 1000nm is 4 dB/km…"

Looking at Chai Gong's research results, Gao Zhendong compared them with the paper in his own head.

"Not bad, not bad, very solid." In comparison, they are almost the same, which proves that our comrades are indeed lacking in theory and direction, but they are not stupid.
"Chief Engineer Gao, we have also done calculations and experiments. When the iron ion concentration drops to 1ppm, a transmission medium with a loss of less than 600dB/km around 20nm can be obtained." Engineer Chai was very excited. As for the reason for his excitement...

"We have also communicated with colleagues from the Communications Institute of the Postal and Communications Commission and commissioned them to do calculations. If we want to carry out long-distance fiber-optic communications with acceptable costs and speeds, the recommended transmission loss of optical fiber is below 20dB/km." This is what excited him. This data is basically in the same order of magnitude as the minimum transmission loss that can be obtained under current technical conditions obtained through their experimental analysis, and the numbers are very close.

"Have you figured out a way to reduce the iron concentration in fused quartz glass?" Gao Zhendong asked with a smile.

This time, Chai Gong's answer was not completely good news, but his confidence and smile remained unchanged: "Not yet, but we have commissioned comrades from Northeast Polytechnic University to conduct relevant research, and the situation is relatively optimistic."

It hasn’t come out yet, but I’m not worried because there are comrades walking side by side with me, pushing my car forward.

Gao Zhendong nodded. Comrades are trustworthy. "So this time, are you planning to get the next step of your work?"

"Yes, yes, yes, the several research tasks you arranged have been completed. The remaining problem of iron ion concentration is being worked on by some comrades, so we have some free time. Considering that the remaining matter does not conflict with other things and can be carried out in parallel, I came here." Waiting is a waste of time, it is better to come here quickly and dig up more information.

Gao Zhendong agreed with his idea. Now that things were arranged, there was no need to wait foolishly. After all, there were more problems to be solved with optical fiber.

He opened the drawer and rummaged through the things inside while smiling, "Yeah, right, right, wait a minute, I'll give you something."

In Chai Gong's opinion, there must be too many treasures in Chief Engineer Gao's drawer, and he has not found them no matter how hard he tries. This makes him very anxious, and he wishes he could take his place and look for them for Gao Zhendong.

But he didn't dare to. He estimated that if he pointed a finger at the drawer, he would be unable to control himself for a long time, and he wouldn't even be able to reach over there.

Finally, Gao Zhendong felt that he had done enough, "Ah, I found it!"

Then, under Chai Gong's eager eyes, he took out a piece of information. In fact, what Chai Gong didn't know was that even if he put his head into Gao Zhendong's drawer, he wouldn't find anything valuable except a pile of blank lined papers with the name of the Sanfen Factory printed on them, because he didn't take this material out of this drawer.

Chai Gong was delighted as he took the materials from Gao Zhendong.

Then, I was dumbfounded...

What the hell! What is written here!

This is Gao Zhendong's direct integration of research on the electromagnetic aspects of laser transmission in optical fibers.

For Chai Gong, he could understand the titles of each chapter, such as "Dielectric Loss", "Bending Loss", "Loss Caused by Radiation", "Information Capacity", etc., but when he entered each chapter, he was dumbfounded and couldn't understand it...

Even though he had been trying his best to study the relevant books recommended by Gao Zhendong, he had to conduct experiments and research while studying at the same time, and it was obvious that he had not absorbed enough knowledge in such a short time.

This article is mostly theoretical analysis, and unlike the original paper which mainly contains result-based discussions and diagrams, Gao Zhendong actually reversed the entire derivation and calculation process based on these results and some reference papers and related theories he could find.

There is a lot of high-energy physics content in it, which is a bit beyond the scope of the Chai Gong at that time, so it is normal that he can't understand it.

This was Gao Zhendong's decision. If Chai Gong and his colleagues were allowed to do this theoretical research on their own, it would take them a long time to learn the relevant knowledge, let alone conduct research, let alone produce results.

So he directly restored this part. Anyway, they were all theoretical analysis and deductive calculations and did not require experimental support. As long as it came from Gao Zhendong, basically no one would have doubts or objections before it was falsified, which was very beneficial to the progress of the entire project.

The only problem is that it is a bit difficult for Chai Gong. Even some of the mathematical tools used in it are not very advanced, strictly speaking, but he still hasn't mastered them.

Otherwise, why would Gao Zhendong take out this thing directly? Normal research really takes time, and Gao Zhendong didn't want to wait. He had already entered the Fengling Yueying Sect, so he had to speed up where necessary.

"This is my research on the electromagnetic properties of light transmitted in optical fiber media. This part may be difficult for you and may take too long. I have already done it. You can use the results directly and learn to absorb them in the process."

Chai Gong's mood at this time was a mixture of emotions, including shame, happiness, admiration, surprise, relief, relaxation, etc.

However, being happy is the most important thing. It is not shameful if Chief Engineer Gao can solve difficult problems.

As for how difficult it is to calculate this material, just think about how I felt when I saw it for the first time. It was like a tiger trying to eat the sky - it had no idea where to start.

"Thank you so much, Mr. Gao. I am so ashamed that you have to personally take charge of these specific tasks for this project despite your busy schedule..." He said this sincerely.

Gao Zhendong waved his hand: "That's not necessary. Leaders are leaders, and they are supposed to lead these leaders, haha. I have also put the recommended books on the back of this achievement, you can refer to it."

Thoughtful, so thoughtful. With such comrades taking the lead, there is no need to worry about not being able to achieve great things!
Chai Gong was feeling emotional while browsing the materials in his hands. He could not help but be excited.
