Chapter 1868 Relaxing Vacation (Part 1)
After all, Colonel Shen and Researcher Qi left feeling extremely ashamed. Guo Tailai didn't make it difficult for them either. From the starting point, they at least wanted to get some latest technology and equipment for the country.
If it wasn't because the starting point is still tolerable, it has been more than a day since Guo Tailai received the people from the Large Magellan Telescope project team here, and it is enough for Guo Tailai to notify the relevant personnel from the general assembly or the navy to come here, then Colonel Shen What they face is not only being taught a few words by Guo Tailai and leaving, they may even be punished.
Teacher Cao is very embarrassed. Strictly speaking, he and Guo Tailai are not a serious teacher-student friendship like Professor Wang. It is also embarrassing to introduce the two of them, but it is not his intention to cause trouble to Guo Tailai, and he keeps apologizing .
Treating Teacher Cao Guo Tailai is another kind of enthusiasm and respect. On the one hand, this is a professor of the school, and no matter what, he is learning with the materials compiled by Teacher Cao. There is always a half-teacher's affection. On the other hand, the relationship between Mr. Cao and Zhao Xiangbei is also good, so we can't neglect it.
After three days of tossing, the large lens was finally accurately installed on the test tower after Guo Tailai made the final adjustment. Through a series of professional calibration observations and tests, the experts sent by the three project teams all came to the same conclusion.
The large mirror starts from the center of the circle, and the part within a radius of 3.5 meters is completely qualified, and it even exceeds the standard by a lot. That is to say, the area with a diameter of seven meters in the center is completely usable, and only the area with a diameter of less than one meter at the outermost edge needs further processing.
Whether it was the two experts who supported Guo Tailai before or Mr. George who opposed it, they were all very pleasantly surprised by the test results. Similarly, they admired Guo Tailai's craftsmanship so much. The test standard is an error of less than 20 nanometers, but after their detection, after various light amplification tests, the machining accuracy of the inner ring is definitely within five nanometers, which is so ingenious that it makes people feel incredible.
As soon as the test results came out, the three people in charge of the test understood that this was Guo Tailai's reassurance to the project team. Where 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 part! You must know that this kind of precision requires that there must be no heavy objects on the mirror. If you want to process the central part, Guo Tailai has to build a bracket above the mirror and then lie on the bracket to process bit by bit. On the contrary, it is the outermost part. The easiest way is to just stand on the ground, and the posture can be much easier.
Now the center part is processed in place, although the outermost ring needs further processing, it does not mean that the processing accuracy is insufficient. According to the requirements of the project team, the accuracy is less than 20 nanometers, and the measured part is less than 18 nanometers. Processing to this point is enough to complete the task. However, in terms of the overall effect, the machining accuracy of the outer ring is inconsistent with that of the inner ring. The inner ring can reach a precision of five nanometers, while the outer ring is still much worse.
Guo Tailai does not deliver the goods because he wants to be consistent inside and outside, which is the pride of the manual processing master. But for the Large Magellan Telescope project team, this is excellent news.
A serious high-tech optical company in the United States, it takes ten years to produce a mirror. Guo Tailai will come here, and it will not exceed two and a half years. The result of a lap. How fast would it be if Guo Tailai usually made it wholeheartedly and honestly?
It is true that the lens polishing is handed over to an American company, allowing the United States to master the large-format and high-precision mirror fine grinding technology, but, as qualified capitalists, the investors and scientific research scholars of the project team, are they willing to wait so long? The same price, high processing quality, and several times shorter delivery time, who should use it? Calculated from the inside out, there are a lot of people in the project team that need to be supported for such a long time, and the salary and bonus project funds are spent like water without producing results. Without qualified capitalists, free market hawkers should know which one to choose, right?
From the perspective of scientific researchers, the earlier the lens is completed, the faster the overall project progress will be, and the sooner the results will be produced after completion. It can be explained to investors, but also has its own research results and reputation. One can be launched soon, and the other will have to wait for decades. Which one to use? I dealt with it tirelessly, and then I didn't use the big telescope until I retired. Is it cheaper for someone who comes later? Who are you working hard for? Americans are so dedicated?
As soon as the test results were sent back to the project team, the entire project team was blown away. According to the test results, the big lenses are actually ready for delivery! Mr. T wants to keep improving, so he has to postpone it for three months. Even so, the progress is much faster than the current progress in the United States!
Now, the project team as a whole was not calm, and had to hold a meeting to discuss who should officially hand over the next few mirrors to process. Fortunately, Mr. T was involved before, so the contract did not stipulate death. If the order for seven mirrors was placed with the American company from the beginning, the project team may cry to death.
The three testers left very satisfied. Among them, the professor from the National Astronomical Observatory of the Chinese Academy of Sciences left with his head up. Do you see it? This is my Huaxia processing master, did you object before? Before Mr. George left, he solemnly apologized to Guo Tailai. In short, it was a happy situation for all. Except for Mr. Adams who left at the beginning.
After the foreign project team left, it was the turn of Professor Wang and his team. In the past few days, Professor Wang has reviewed all the principles of Guo Tailai's new large-format high-precision grinding machine, and only the test is left. In principle, it must be no problem, and it is very simple. The difficulty lies in the precision of processing and installation, the means and tools of measurement, and various fine controls in the fine grinding process, such as temperature, such as the uniformity of the abrasive, etc. .
The effect of on-site processing is also very gratifying, but there is one thing, the speed is still a little slow to achieve the precise large-diameter mirror radian effect, but it is already much higher than the efficiency of the current American company.
"The accuracy decreases with the increase of the processing diameter." They are all professionals. Guo Tailai only mentioned one sentence, and Professor Wang immediately understood: "At present, the best fine grinding effect is the lens with a diameter of less than six meters. The accuracy can It reaches ten nanometers. At present, diamond abrasives are still used, and if the caryne research results at the school are realized, I believe that the use of carbyne abrasives will have a better effect, and diamonds can be directly ground, not to mention silicon carbide."
"You did a good job, Fatty!" Professor Wang was simply too satisfied. This disciple really didn't pay for nothing, he has such a long face.
"Say something to Principal Gu for me." Guo Tailai and Professor Wang sat side by side, looking at the high-precision grinding machine in the studio with a smile: "I have completed the task that the old man entrusted to me."
