Chapter 934： A relaxing holiday (on)

After all, Colonel Shen and Qi Researcher were ashamed and left. Guo Tailai did not embarrass them. From the starting point, at least they still wanted to get the latest technology and equipment for the country. Although they were stupid in practice, they could not be killed with a stick.

If it ’s not because the starting point is still tolerable, Guo Tailai has received the people of the Large Magellanic Telescope project team here for more than a day. It is enough for Guo Tai to notify the general assembly or naval personnel to come over in one day, then Colonel Shen What they faced was not just to leave Guo Tailai in a few words, maybe he would be punished.

Teacher Cao is very embarrassed. He and Guo Tailai are strictly speaking, and it is not a good relationship between teachers and students like Professor Wang. It is impossible to introduce the two people to come over, but it is not his intention to cause trouble for Guo Tailai. .

Treating Cao teacher Guo Tailai is another passion and respect. On the one hand, this is a professor at the school, and it can be regarded as a study with the information compiled by Mr. Cao. There are always half-teacher points. On the other hand, the relationship between Teacher Cao and Zhao Xiangbei is not bad.

After three days of tossing, after Guo Tailai finally made the debugging, the large lens was finally accurately installed on the test tower. Through a series of professional calibration observations and tests, the experts from the three project teams all reached the same conclusion.

The big mirror starts from the center of the circle, and the part within a radius of three meters and five is completely qualified, and even exceeds the standard. That is to say, the area with the center diameter of seven meters is completely usable. Only the area with the edge of less than one meter is left, which needs further processing.

Whether it was the two experts who supported Guo Tailai or Mr. George who was against it, they were all very pleasantly surprised by the test results. Similarly, for Guo Tailai's craftsmanship, he simply admired the five body cast. The test standard is an error of less than 20 nanometers, but after their detection, after various light magnification tests, the processing accuracy of the inner ring is absolutely within five nanometers, which is incredible.

As soon as the test result came out, the three people in charge of the test all knew it. This was Guo Tailai's heartfelt pill for the project team. What is the most difficult part to process a large mirror with a diameter of more than eight meters by hand? It must be the center! You must know that for this precision requirement, there must be no heavy objects on the mirror. If you want to process the central part, you have to put a bracket above the mirror and then lie on the bracket to process it little by little, but it is the outermost circle. The simplest, as long as you stand on the ground, the posture can be much easier.

Now the center part is processed in place. Although the outermost ring needs further processing, it is not to say that the processing accuracy is insufficient. According to the requirements of the project team, the accuracy is lower than 20 nanometers, and the measured part is below 18 nanometers. Processing to this point is enough to complete the task. But in terms of overall effect, the machining accuracy of the outer ring is inconsistent with that of the inner ring. The inner ring can reach an accuracy of five nanometers, and the outer ring is still much worse.

Guo Tailai did not deliver because he wanted to be consistent inside and outside, which is the pride of the master of manual processing. But for the Large Magellanic Telescope project team, this is excellent news.

It ’s a ten-year-old American high-tech optics company. It takes ten years to produce a mirror. Guo Tai ’s coming here will not exceed two and a half years. This is still Guo Tailai ’s two-month flight driving school. The result of a lap. If Guo Tailai usually made a wholehearted and honest production, how fast should it be?

Although this lens polishing is handed over to American companies, it will allow the United States to master large-scale and high-precision mirror finishing technology, but as qualified capitalists, those investors and scientific researchers in the project team are willing to wait so long? The same price, high processing quality, several times shorter delivery time, who uses it? Counting from the inside and out, we have to keep a bunch of people in the project team for such a long time. The wages and bonuses will not be able to produce results through the flow of funds. Without using qualified capitalists, free market hawkers should know which one to choose?

From the perspective of scientific researchers, the sooner the lens is completed, the faster the overall project progress and the sooner the results will be produced after completion. Not only can it explain to investors, but also have its own research results and reputation, one will start soon, and one will have to wait for decades, which one to use? I'm tired of dealing with it, and I didn't use the big telescope until I retired. Is it cheaper for later people? Who are you working hard for? Are Americans so dedicated?

As soon as the test results were sent back to the project team, the entire project team was frying. According to this test result, large lenses are already ready for delivery! Mr. T wants to keep improving, so it has to be postponed for three months, even if it is so, it is much faster than the current progress on the US side!

At this point, the project team as a whole was not calm, and had to meet to discuss who should formally hand over the next few mirrors. Fortunately, because Mr. T had inserted a leg before, the contract did not stipulate death. If the seven mirror orders were placed for the American company from the beginning, it is estimated that the project team could cry to death.

The three testers left with great satisfaction. Among them, the professor at the National Astronomical Observatories of the Chinese Academy of Sciences left directly with his head raised. Do you see it? This is my master of processing in China. Did you object? Before he left, Mr. George very seriously apologized to Guo Tailai. In short, it was a happy situation. Except for the Mr. Adams who left at the beginning.

When the foreign project team left, it was Professor Wang ’s team. In the past few days, Professor Wang has reviewed everything about the principle of this new large-format high-precision grinder from Guo Tailai, leaving only the test. In principle, there is no problem, it is also very simple, the difficulty is still the accuracy of processing and installation, the measurement methods and tools, and various fine controls during the fine grinding process, such as temperature, such as the uniformity of the fineness of the abrasive, etc. .

The effect of on-site processing is also very gratifying, but one thing is that, if you want to achieve a precise large-diameter mirror curvature, the speed is still slightly slower, but it is already much more efficient than the current US company.

"Accuracy is reduced as the processing diameter becomes larger." All are professionals. Guo Tailai only mentioned a sentence of Professor Wang to understand in seconds: "At present, the best precision grinding effect is still a lens with a diameter of less than six meters. It reaches ten nanometers. At present, diamond abrasives are used. If the acetylene research at the school is successful, I believe that acetylene abrasives are more effective, and diamond can be directly ground, and silicon carbide is not a problem. "

"Good job, fat!" Professor Wang was so satisfied. This disciple didn't accept it in vain. His face was too long.

"Say a word to Principal Gu." Guo Tailai and Professor Wang sat side by side and looked at the high-precision grinder in the studio with a smile: "I have completed the task his old man gave me."
