The next day, Su Zhe was woken up by the alarm at 6:30 in the morning. When he got up, he found that Fan Xiaoming had already left the dormitory.
After washing up, he went out carrying a cloth handbag containing White Rabbit toffee. After breakfast in the cafeteria, he bought five large steamed buns and put them in his handbag.
He thought about using these three days to analyze the first five test data to see if he could find the cause of the failure, and also try to break through the ion beam polishing technology.
As for buying steamed buns, they are for lunch, because it takes ten minutes to walk from the cafeteria to the Optical Lens Research Center, and it takes twenty minutes to go back and forth.
Arriving at the Optical Lens Research Center, Su Zhe put his handbag in the office and went to the Ion Beam Polishing Technology Research Laboratory.
He found that everyone was there. There were thirty-two people in the entire laboratory, including Bao Zhengyi and Fan Xiaoming, and these people were all busy with what they were doing.
Many people didn't notice his arrival, and those who saw him just smiled at him and went about their business.
Coming behind Fan Xiaoming and Bao Zhengyi, Su Zhe watched the two people busy attentively. After a while, Bao Zhengyi discovered him.
"Xiao Zhe is here!"
"Professor Bao! You are busy with your business, don't worry about me." Su Zhe nodded with a smile.
Bao Zhengyi smiled and turned around to do his own business.
At this time, Fan Xiaoming turned around and said, "You're here so early, don't get more sleep!"
"It's late, it's already past seven...Brother Xiaoming! If you continue, I'll come over and take a look." Seeing Fan Xiaoming talking to him without taking his hands off the keyboard, Su Zhe knew how busy he was now.
"Okay! When these three days are over, I'll treat you to a big dinner." After Fan Xiaoming finished speaking, he turned around and went about his own business.
Su Zhe stood behind Fan Xiaoming and looked at the data on the display for a while, then looked at the two ion beam polishing equipment being processed through the two circular windows, and then quietly left the ion beam polishing technology research laboratory.
Now is the critical moment, so it's best not to interrupt.
On the way back to the office, I met researchers from other laboratories who came to work. These people were curious about his appearance, but no one asked.
Back in the office, he logged into the research center data system using his campus card number.
Find the first five test data from the Ion Beam Polishing Technology Research Laboratory.
Open the fifth test data and take a cursory look at the data directory.
There are processing workpieces, that is, the material composition of optical lens lenses, the principles and various parameters of ion beam polishing equipment, detectors such as full-band electromagnetic wave receivers and particle detectors, and various parameters of the processing environment.
Next comes testing, which is the recording of real-time raw data during the processing process and the results of relevant data analysis.
Finally, there is a summary of the fifth test.
He looked at the number of pages of the data. There were more than a thousand pages. This was because only part of the original data was used. If all the original data from various detectors were included, how many pages would it take?
He saw a hyperlink at the end of the summary, a real-time raw data file of the entire process, with a file size of 8.31T.
The test data is divided into two groups, one group with positively charged ion beams and one group with negatively charged ion beams. The material composition of the corresponding processed optical lens lenses is also different.
Su Zhe filled his teacup with water and sat in front of the computer to look at each item.
Let’s start with the material composition of the optical lens.
Mainly silicon dioxide, calcium hydroxide, boron oxide, lead oxide, zinc oxide. The material composition of the optical lens lenses tested in the two groups is the same, but their proportions are different.
There is also related data such as the molecular structure of the optical lens.
The ion beam data are equally detailed.
What surprised him was the data detected by the full-band electromagnetic wave receiver and particle detector.
The full-band electromagnetic wave receiver is said to be full-band, but in fact it can only detect electromagnetic waves with a wavelength of 1m to 1pm. Radio waves with a wavelength of more than one meter and gamma rays with a wavelength of less than one picometer cannot be detected.
The function of the particle detector is very powerful. It can not only identify particles of various sizes, but also detect the relative position of the particles.
However, the particles being detected need to meet certain conditions before they can be detected.
After he read the data related to the processing environment, he did not look at the real-time raw data and test results.
He stopped and quickly calculated in his mind based on the existing data. After calculating the key data, he recorded the data on A4 paper.
Half an hour later, he had filled up the data on four A4 sheets of paper and calculated the results. The processed optical lens did not meet the design requirements.
He had to admire himself. Since his head was opened, he could not forget things without forgetting them, and his understanding and calculation skills had greatly improved.
Of course, doing this consumes energy. It was only halfway through the morning and his stomach was already growling with hunger. He had no choice but to pick up the White Rabbit toffee on the table and stuff it into his mouth.
I wiped the sweat from my forehead and started to look at the test, that is, the real-time raw data and processing results of processing.
When looking at the real-time raw data, we compared it with the data he had calculated. At first, the processed real-time data was basically consistent with what he had calculated.
As he looked at it, he felt something was wrong with the group of negatively charged ion beams.
During the process of workpiece processing, the full-band electromagnetic wave receiver receives multiple sets of X-rays with different wavelengths.
These X-rays with longer wavelengths include eight groups: 1.25 nanometers, 1.36 nanometers, 2.50 nanometers, etc.
There are also two sets of X-rays with shorter wavelengths, 0.02 nanometers and 0.1 nanometers.
Suppressing the confusion in his heart, Su Zhe quickly read through a thousand pages of data, and the time had already reached 12 noon.
The test, that is, the processing results are similar to what he calculated. The optical lens processing results can only reach a peak-to-valley surface accuracy of 0.8 nanometers and a surface roughness of 150 picometers, which is far from the peak-to-valley surface precision and surface roughness of 0.12 nanometers. There is still a big gap in the surface roughness of 20 picometers.
This is true regardless of whether the beam is a positively charged ion beam or a negatively charged ion beam.
After briefly analyzing the results, he couldn't think of a way to improve the accuracy after thinking for a long time. Maybe he was thinking about the multiple sets of X-rays of different wavelengths generated during the processing.
When he was about to take a closer look at those X-rays, his stomach kept ringing and hunger filled his body.
After thinking about it, I took out five large steamed buns from my handbag, drank them with warm water, and ate them in three to five times.
By the way, the steamed buns served at Shangling University are really big and cheap. Normally, a girl would be full after eating half of them.
He ate five of them at once, and at this moment, he felt an indescribable sense of satisfaction.
Looking at the almost half a pound of White Rabbit toffee on the table, I felt like I wouldn't be able to last through dinner.
The brain has become smarter, but the energy consumed has also skyrocketed.
Fortunately, the energy consumed is related to the intensity of brain use, rather than continuous consumption.
Another problem is that as long as he uses his brain intensively, he will sweat on his forehead, his body temperature will also increase, and then he will sweat all over his body.
According to his estimation, after high-intensity brain use, the brain will generate a large amount of heat, and sweating is to dissipate heat, which also indicates the need to drink a lot of water.
For this reason, he replaced the 500 ml water glass with a 5 liter water glass.
After drinking half a glass of water, he was full and began to explore the origin of those X-rays. Among them, he knew the origin of X-rays with a wavelength of 1.25 nanometers. Eighty percent of them were produced by high-energy free electrons hitting calcium atoms.
X-rays of other wavelengths require him to calculate and view the original data...
