At 7:30 on the second day, teacher ye walked into long Jianhua''s laboratory and saw long Jianhua and Bai gangpeng busy with two pairs of giant panda eyes.


    "Are you two staying up late?"


    Long Jianhua smiled and nodded.


    Bai gangpeng smiled bitterly, "teacher, I was caught by younger martial brother long and stayed up for three days and two nights in a row. You see, my black eye area is five times his. "


    Mr. Ye nodded slightly and praised in his heart.


    Doing scientific research needs such talents and efforts.


    Think and do; You can move your hand and carry it.


    Also very moved, "why don''t you rest today and continue tomorrow?"


    Bai gangpeng said quickly, "no! Teacher, we have pulled one ten meter long, several five meter long, and more one or two meters. Every time, it is interrupted because of a small problem with the equipment. This time, we have rectified all the problems we thought of. Younger martial brother long said that we should work hard to pull one more than 100 meters today. "


    Mr. Ye''s saliva came out. "Are you sure what you pulled out is optical fiber? Ten meter long optical fiber? "


    Long Jianhua glanced at Bai gangpeng. Elder martial brother Bai said with a smile, "teacher, I have detected that under the condition of long wavelength of 1.31 microns, the attenuation value of the 10.5-meter optical fiber is 0.40dbkm, which is lower than the data collected by younger martial brother long. However, this data is only detected by myself, and the official data needs to be detected by authoritative institutions. "


    Mr. Ye grabbed long Jianhua and asked eagerly, "where is the optical fiber?"


    Long Jianhua turned to the finished product cabinet, took out six rolls of small coils and calmly handed them to him, "teacher, this is a nine micron single-mode, one meter to ten meters."


    Mr. Ye''s hand on the optical fiber ring trembled.


    It is certain that this is an optical fiber with a length of more than one meter developed by our own laboratory, especially an optical fiber with such a low attenuation value.


    He patted long Jianhua on the shoulder, "very good! I didn''t expect to pull out such a long silk so soon. Today, I want to see you pull out 100m optical fiber and witness the birth of 100m optical fiber in China! "


    Long Jianhua smiled bitterly and didn''t know how to respond.


    Bai gangpeng swallowed his saliva and said softly, "teacher, we pulled this ten meter long optical fiber for almost eight hours, and we failed many times in the middle..."


    Mr. Ye looked at them blankly, and then patted his forehead. "I said it wouldn''t be so simple to do things. Then are you ready now... "


    Long Jianhua smiled bitterly, "100 meters is just our goal. The first time I pulled, I didn''t have enough experience. There are many problems with the equipment. Elder martial brother Bai and I have just finished it; There''s not enough gas. I''ll get it right away. "


    Mr. Ye waved, "I don''t know about the equipment. I''ll arrange the gas."


    Then he went to the door, didn''t care about his identity as vice president, and shouted loudly.


    Soon, two graduate students of grade 79 and a teacher ran over.


    Mr. Ye said to the two students, "go get fuel - from now on, you follow long Jianhua until the experiment is completed; Xiao Hu, you go to the testing center to measure the attenuation value of these optical fibers and ask them to issue a report. "


    Mr. Hu''s eyes brightened. "Dean ye, do you think this is optical fiber? Isn''t it possible for us to do so many experiments? "


    Mr. Ye nodded.


    The heart says you are excited, I am more excited.


    It is not only about the experimental materials of our college, but also a major event that the domestic optical fiber level has stepped into the forefront of the world.


    Awesome, awesome, Long Jianhua!


    The two graduate students asked long Jianhua what gas they wanted and left immediately, while Mr. Hu still stood there, looking at the rolls of optical fibers in his hand with hot eyes.


    Mr. Ye patted him on the shoulder and stared at him.


    What are you waiting for here?


    Miss Hu stared at Miss Ye.


    Can I use some first? Testing doesn''t need so much.


    Teacher Ye waved his palm out, "take it for testing first. After testing, give priority to you!"


    Mr. Hu answered happily, turned and ran, and pedaled and disappeared in the corridor.


    Mr. Ye rubbed his face hard, took a deep breath and walked into long Jianhua''s laboratory. His steps were much lighter than when he just went in.


    If you don''t pull, you''ll come out ten meters; If you don''t do it, you have to reach the international advanced level.


    Long Jianhua, what tasks should be arranged for him next time


    Long Jianhua, who was fine-tuning the equipment, suddenly felt his heart tighten slightly. After feeling it for more than ten seconds, he didn''t find such a situation again. He shook his head and continued to operate.


    "Maybe it''s caused by a serious lack of sleep these days. The next experiment can''t be so excited. If you should sleep in turn, you should have a good sleep."


    Bai gangpeng looked at him suspiciously, "what''s the matter? Have you found a new problem?"


    What new problems have you found?


    Long Jianhua shook his head. "Are you hungry? I went out to buy breakfast. "


    Teacher Ye quickly said, "I''ll find someone to buy it for you. Fried dough sticks and soybean milk! "


    Long Jianhua immediately stood up. "Teacher, I''ll go out and eat myself. Soon."


    Elder martial brother Bai said with a smile, "teacher, you scared younger martial brother long when you said soybean milk. I bought him a soybean milk the day before yesterday and threw him up... "


    Teacher Ye laughed, "Kyoto soybean milk is a major feature. You''re not used to drinking it. It''s strange."


    Long Jianhua smiled bitterly, "I ate pig suet when I cut in line. This soybean milk is worse than that."


    Fried dough sticks are OK. Soybean milk has a bad smell. I''m not used to it.


    Soon, long Jianhua came back from breakfast outside and helped Bai gangpeng bring back fried dough sticks and soybean milk.


    At this time, the gas had been delivered, and the two graduate students stayed in the laboratory, listening to Bai gangpeng''s experimental introduction with Mr. Ye and Yu Kehui.


    Long Jianhua glanced at Yu Kehui and looked at him with disdain. He couldn''t help wondering where the great God was dissatisfied?


    I didn''t care so much. Seeing that elder martial brother Bai has connected the hydrogen and oxygen, turn on the heating device, put the preform on the chuck of the feeding mechanism, and turn on the motor after alignment.


    When the preform enters the heating device, turn on argon to create a protective atmosphere.


    The preform softens, the molten glass drips out from the bottom nozzle and solidifies into a silk thread with a small ball, and the optical fiber is formed!


    Long Jianhua quickly cut off the ball. Grasp the optical fiber head end, bypass the tension wheel, guide wheel and traction wheel on the drawing tower, and finally wind it on the take-up reel.


    Then, start the take-up device.


    This process is boring.


    Ten minutes later, the take-up reel only turned 20 times; The preform was slower and only advanced one and a half centimeters.


    "Cough, younger martial brother Bai and younger martial brother long, I''d like to make a suggestion for your experiment."


    Seeing that five people, including Mr. Ye, turned to look at themselves, he pinched and said bravely, "I think the speed can be adjusted a little faster."


    Long Jianhua looked at him in amazement.


    Two big words burst out in my heart, I am the second Olympics!
