The original intention of replacing the valence glass inner tube with glass fiber is to save the cost of training materials, and at the same time to increase the difficulty of training according to your wishes.

After consulting with a local glass craft factory, I thought that fiberglass would be very difficult.

Didn't expect a fire to burn the fibers out?

After calming down, Zhang Yuanwen began to think, "Where did you learn this method?"

"Clamping the glass rod into a cone should be the key to drawing. You don't know how to read this kind of technology in a book, and who would write about this key technology in a book?"

Although Zhang Yuanwen is limited by the times, his knowledge is much worse than Jiang Jiuling's, but his eyesight is not bad.

"I saw it in a science magazine. Jiang Jiuling had already thought of a countermeasure, "The three of our original Crimson Arc Interest Group were in order to study the rapid expansion attack methods of those chariots in the robot chariot arena. Concubine Zhao in the team asked her father to ask a friend to bring many scientific magazines from Xiangjiang. ”

"Many of these magazines are in English, and when I was looking up the English dictionary translations, I happened to read an academic article on how fiberglass becomes fiber. ”

"Those magazines have Discover, New Tech, and BBC Focus. ”

In addition to the fiberglass, Jiang Jiuling did not make it up.

Discovery and New Era of Science are both world-renowned technical and scientific journals, and many internationally renowned scientists have published articles in these two journals.

BBC Focus Magazine is published in the United Kingdom, and it is in this magazine that the three members of their interest group have found many technical introductions to the champion robot chariot.

The results of the three members of the interest group are not bad, and Wucheng No. 2 Middle School is a key middle school in Wucheng, and English courses have been taught since junior high school.

Therefore, the three members of the interest group can understand at least half of the content of the magazine after comparing it with a professional English dictionary sentence by sentence.

"Director, the kind of glass fiber spinning technology introduced in scientific magazines is used to produce optical fibers. ”

"I heard that if you put a glass rod on a multi-story tall wire drawing tower, as long as the glass rod is continuously heated, the end of the rod will automatically droop into a hair-thick fiber under the influence of gravity. ”

"When I was in the interest group, I also tried to draw the glass with an air cutting gun, and I was able to pull out the fiberglass smoothly today. ”

"It's so easy to produce optical fiber?" Zhang Yuanwen certainly knows about optical fiber.

It is said that this new optical fiber communication technology is thousands of times the transmission capacity of cables. There are also rumors that the United States is planning to pull optical fiber from the bottom of the sea all the way to Asia, and several countries are vying to share an interface to their doorstep.

Huaxia has the technology to manufacture fiber optic cables, but this technology is concentrated in one or two technology companies with top title scientists.

Thinking of this, Zhang Yuanwen couldn't help but feel that he couldn't keep up with the development of science and technology.

Although he won the title of slag remelter engineer, but now electronic technology has entered an unprecedented stage of rapid development, and European and American countries seem to have new technological breakthroughs every week.

For electronic technology, he really feels old.

"The magazine said it was hard, it was hard. Jiang Jiuling's expression was full of memories, but he was not recalling the contents of the magazine, but recalling the reserve knowledge in his mind.

"It's not difficult to pull the fiber into a hair's thickness, but the difficult thing is how to produce the fiber prefabricated glass rod. ”

"It is said that the purity requirements of this prefabricated glass rod are particularly extreme, because when a preform is pulled into a fiber tens of kilometers long, it is equivalent to the thickness of the fiber reaching tens of kilometers. ”

"When the light shuttles through dozens of kilometers of glass, the purity is not up to standard, and the light signal will quickly weaken. ”

Zhang Yuanwen asked with some mixed emotions, "Is this magazine about optical fiber still in your hands?"

"I'm not sure......" Jiang Jiuling could only continue to round the field for his own words, "Concubine Zhao asked her father to get a lot of scientific magazines, and the content of the fiber should be in the [Discovery] magazine." ”

"I only have one [Discovery] magazine at home, and most of the remaining magazines are in Concubine Zhao's house. But Concubine Zhao said that her father's friends had borrowed some magazines, and they were all borrowed but not returned. ”

"[Discovery] ......" Zhang Yuanwen nodded, the higher-level industrial committee has always subscribed to those open scientific journals from European and American countries. Of course, there are world-famous magazines like [Discovery], but these famous magazines are in English, French, and German.

Once foreign languages involve those professional field words, it will become more difficult than heavenly books.

Looking through professional foreign language dictionaries, I am afraid that I can turn people's hair out.

Zhang Yuanwen called Jiang Jiuling to the office on the second floor again, and several experimenters in the laboratory were holding a cutting gun, one holding a glass rod with fire tongs, and the other with needle-nosed pliers trying to repeat Jiang Jiuling's silk drawing process.

"I heard you were expelled from school?"

"Hmm~ The school is worried that the Provincial Industry Committee will make a decision to expel the three of us after the investigation is over. ”

There is nothing to hide this, Jiang Jiuling can see that Director Zhang admires him very much, "If you are expelled by the Industrial Commission, you will have to go through the process of the Education Bureau, and the expulsion record will be left on the student record." ”

"It's not difficult to continue studying, and with your intelligence, I don't think any school will refuse. ”

Zhang Yuanwen's eyes kept on the glass fiber on the desk, "It's just that you have been taking a break from school at home for three months, and if you enroll in this semester, there will be more than a month to take the college entrance examination, I'm afraid your grades will be greatly affected." ”

"I've been reviewing my senior year courses for the past three months, and I don't think I'll drop much. ”

"How many middle schools do you want to go to?"

"I can introduce you to it. ”

Jiang Jiuling said that he should be able to solve the problem of going to school, and if he encounters difficulties, he will trouble Director Zhang.

Zhang Yuanwen glanced at this young man who was thin but radiant from beginning to end, and couldn't help but want to laugh, "You're quite confident." ”

"Let's talk about this fiberglass. ”

"You make it, and the technique of pulling the wire from the glass rod is simple and straightforward. As long as you make a small hole in the metal ball, and then fix one end of the glass fiber to the wooden board, you can easily practice the metal movement ability. ”

Zhang Yuanwen said softly while pinching the extremely tough glass fiber with his hand: "If this method is popularized, I think most of the extraordinary engineers who have mastered the ability to move metal will choose it as a practice tool." ”

"It's a pity, but it's because its technology is so simple and straightforward. Even a high school student can figure it out, those monkey spirit guys, when they see this kind of fiberglass, how can they not figure out the reason. ”

"It's hard to bring you any wealth with these fiberglass fibers in front of you. ”

"You learned it from magazines, so you can't use it to get a title reward in front of the Holy Spirit Patent Codex. ”

Speaking of this, Zhang Yuanwen's tone became negotiable, "I can give you a few comments for reference." ”
