Chapter 166

Teacher ye, sitting on the small square stool, turned to look at him. Bai gangpeng stared at him. The two graduate students looked at him in confusion; Only long Jianhua turned his head again and looked at the temperature display of the heating furnace.

Seeing so many people looking at him, elder martial brother Yu was very proud, "if you speed up the feeding system, you can speed up the take-up device; At the same speed on both sides, the system still works normally. "

Hearing what he said, Miss Ye looked very ugly.

Ning Xinhua, a new graduate student of grade 79, said cautiously, "elder martial brother Yu, it doesn't seem to be all about speed, does it? Among other things, whether the preform can be completely melted is a big problem. "

Yu Kehui said with a smile, "that's easy to do. Just raise the temperature. The temperature of hydrogen and oxygen flame can reach 2500 to 3000 degrees. Now the temperature display is only 2000 to 1000 degrees, and there is still a lot of room. "

There's nothing wrong with that. It's right.

Bai gangpeng said faintly, "how to control the uniformity of optical fiber? Our current operation level is already in the best state. The diameter of the optical fiber is uneven. How to control the acceleration? "

Uh, uh, uh

Yu Kehui was stunned, as if he had never considered such a problem.

But do I need to consider such a problem? I'm just offering a suggestion.

Whether to mention it or not is my business, and whether to accept it or not is your business.

Absolutely no problem!

Long Jianhua said faintly, "elder martial brother Yu, you can't get up as fast as you want. If you can build 100 meters in one minute, where can elder martial brother Bai and I use to stay up late here? Where do we need to toil here to test the speed of two sets of equipment? "

"Indeed, the speed can be accelerated. Raising the temperature and accelerating the feeding speed and wire drawing speed are all the ways to solve the problem. However, the process of wire drawing is actually a process to ensure that the surface of the optical fiber is not damaged; Another important point is that this is a process of correctly controlling the outer diameter and refractive index of the core cladding. "

In a word, this is making optical fiber, not sweet potato noodles.

Yu Kehui breathed quickly, his eyes began to turn red, and the blue tendons on his neck were exposed.

Hit, insulted!

But he immediately reacted and secretly took a deep breath, so that the blue tendons disappeared and the red eyes returned to their normal color.

"So my suggestion is abrupt."

Elder martial brother Bai gangpeng said faintly, "younger martial brother Long's plan has been reviewed by the teacher, and the calculation in it has been calculated by the teacher himself. To tell you the truth, I thought so at first, but when I saw younger martial brother Long's plan, I felt ignorant. "

This is a mending knife.

Who can't think of such a simple question?

Who wants to keep the feeding speed of the preform at only nine centimeters per hour when doing the experiment? Who wants to waste their youth here?

Don't easily question other people's experimental plans, which is the most basic common sense of scientific and technological workers.

If you want to be in the limelight, you must have a keen mind and a wide range of knowledge.

Using fur to question profundity can only be a joke, leaving others with a laughing stock.

Mr. ye turned his head and glanced at him lightly, "Ke Hui, hurry to improve your experimental scheme, recalculate what should be recalculated, pay attention to the reaction process, pay attention to the reaction process. Doing experiments is not a sign of determination, not a pat on the head. Go ahead. Don't watch the excitement here. "

The layman watches the excitement while the expert watches the doorway.

You Yu Kehui are here to watch the excitement.

Yu Kehui's breathing became urgent again, his eyes turned red quickly, and the blue tendons on his neck began to bulge.

"Teacher, I went to do the experimental plan."

Before Mr. Ye said, he swished out.

Never stay here again. It's too hard. I'm still hard hit in front of my tutor, and I'm told by my tutor to watch the fun.

He wanted to pat himself on the mouth and let himself lose points with the teacher.

No, we should not blame ourselves, but long Jianhua, Bai gangpeng and Ning Xinhua!

I'm just making a suggestion. Is it my fault to give you suggestions? You can't let others question you?

Even if I'm not thoughtful, can't you stop talking in front of the teacher?

You are all villains!

You three little people, wait!

Fang Shengli, another new graduate student, said carefully, "elder martial brother Yu seems to be crying."

Is he going to cry? Are you angry?

Bai gangpeng thought so.

Is he going to cry? The mentality is so fragile. How did you become a teacher for more than ten years?

Miss Ye thinks so.

Is he going to cry? No, nothing.

Ning Xinhua thought so.

Is he going to cry? Let him cry.

Long Jianhua thought so.

Finally, no one went to his lab to see if he was crying.

People in their forties have experienced great storms. What can't they bear?

Can't bear it? Then... I can't bear it!

Long Jianhua and Bai gangpeng continue to keep an eye on the temperature, touch the temperature and vibration of small equipment from time to time, and adjust the center of the preform

"Jianhua, how do you know that the optical fiber is uneven in thickness? Can it be controlled in this production process? "

"Teacher, we measured it after the end. In the laboratory, we can't solve such a problem. I don't know if others can solve such a problem. "

"Hehe, you are the only one who can pull out a meter long in China - of course, I don't know the situation yesterday and today. Like you, you may not have detected the results, so you didn't report it."

As time goes by, the take-up device is still rotating steadily as usual, and the outer optical fiber has been wound with a thick layer.

The feeding system of optical fiber preform is normal, the heating system is normal, the wire drawing mechanism is normal, and the water cooling and atmosphere protection and control system are normal

Long Jianhua and Bai gangpeng looked more and more excited. Teacher Ye's eyes also showed expectant eyes. Pulling out 100 meters at one time is not a dream!

Hope is at hand!

"How long has it been?"

Teacher Ye finally couldn't help being excited and asked in a trembling voice.

Ning Xinhua looked at his watch, "ten twenty-six."

Then he jumped up, "fifty minutes? Ninety meters an hour, seventy-five meters? "

Teacher Ye smilingly put her index finger in front of her lips and made a silent gesture. Ning Xinhua quickly covered her mouth and stared at long Jianhua with wide eyes.

Why isn't he excited?

Turn around and look at Bai gangpeng. He has no sign of excitement.

Bai gangpeng glanced at him and longjianhua.

Younger martial brother Long's plan and equipment made by younger martial brother long have failed several times. Will 100 meters be a problem?

The preform is shortened cm by cm, and the take-up device still operates steadily

Ten thirty, normal.

Eleven o'clock, normal.

Eleven thirty, normal

At eleven fifty, all the preforms entered

"Ding ~ wordy ~"

After five past twelve, all the preforms were pulled into wires, and the ends were hit on the metal support, making a pleasant sound.

"Yes! At least 200 meters! Ha ha, long Jianhua, you succeeded! "

Mr. Ye jumped up, completely without his usual steadiness.

Long Jianhua suddenly felt his nose sour and felt like crying.
