Su Zhe put away the three books in his hand and looked at the time on his phone.

Ten past eight.

He recalled that he read "Mathematical Analysis I." at about three o'clock in the afternoon, and finished reading it at six o'clock.

Read a book in three hours and be able to grasp the knowledge in the book.

As for the side effects, it is probably a lot of brain power, and the brain needs a lot of energy to expend.

I did a brain CT scan in the morning, and there was no problem, which means that there is nothing bad in his head.

When I thought of this, I didn't think about it anymore.

I looked at Mathematical Analysis II on my desk, flipped to the table of contents, and began to study.

As time went on, there were still not many people in the study rooms on the fourth floor of the library, and there were very few students who studied seriously.

But the whispers of a few couples, if you listen carefully, you can still hear them.

Su Zhe didn't care about this, and he didn't have the heart to listen to the whispers between lovers, he was completely immersed in books.

After reading "Mathematical Analysis II.", he quickly opened "Mathematical Analysis III.", and halfway through his view, the radio in the study room sounded.

"It's 10:50 at night, and there are still ten minutes left before the time to turn off the lights, so please leave the students who haven't left."

Su Zhe raised his head and swept around, and he was left alone in the entire study room.

He closed the half-read copy of Mathematical Analysis III. and counted the time.

In nearly three hours, I finished reading "Mathematical Analysis II." and half of "Mathematical Analysis III.", and my efficiency has improved a lot.

He touched the sweat on his forehead and felt a hint of hunger, everything else was fine.

Grab your books and head to the cafeteria.

Although it was eleven o'clock at night, there was a restaurant in the cafeteria with the door open, and he ordered a bowl of somen noodles.

After eating the noodles, on the way back to the dormitory, he found that the supermarket was still open, so he went to the supermarket to buy a large bag of White Rabbit toffee.

When I returned to the dormitory, I found that Fan Xiaoming had not returned.

It's late enough for this shift.

He put away the three books he had borrowed, washed up and prepared for bed.

Just after washing, Fan Xiaoming came back, and the two happened to meet in the living room.

"Xiao Zhe! Why are you doing it so late, don't tell me you were rushed back by the study room broadcast. Fan Xiaoming put down his computer bag and took out his laptop from his computer bag.

"Yes!" Su Zhe nodded and replied.

"Well, you can go back to the dormitory to read the book, no one bothers you anyway." Fan Xiaoming opened the laptop.

"There is free air conditioning in the study room, and I also like the atmosphere of the study room." Su Zhe came to Fan Xiaoming's side and looked at the laptop screen.

The screen is a data that refreshes quickly, and it is difficult to understand.

"That's right!" Fan Xiaoming got up and poured himself a cup of tea.

Su Zhe saw Fan Xiaoming sitting on the sofa with tea, he pointed to the laptop screen and asked, "Brother Xiaoming!" What are you doing here? ”

"Analyze the data!" Fan Xiaoming took a sip of hot tea and explained, "You know that I followed my mentor to study the optical lens of EUV lithography machine, the manufacture of this optical lens is very troublesome, and the material composition of the optical lens will not be talked about for the time being, let's talk about the mirror processing of the optical lens, which ......"

Fan Xiaoming spoke very carefully, and Su Zhe listened very seriously.

Currently, it is Europa's company Chase that supplies optical lenses to BSML, the manufacturer of EUV lithography machines.

Chase Company uses precision machine tools to mill the lens of the lithography machine, and then polishes it with a small grinding head, magnetorheological polishing and ion beam polishing to achieve a surface accuracy of 0.12 nanometers and a surface roughness of 20 picometers.

"Now, with more advanced CNC optical machining centers, which include stress disc polishing and magnetorheological polishing, the optical lens can achieve a peak-to-valley value of 10 nanometers of surface accuracy and a surface roughness of 2 nanometers." Fan Xiaoming said with some pride.

"Can we produce this kind of CNC optical machining center in-house?" Su Zhe asked.

"Yes!" Fan Xiaoming said with some frustration, "Now, our problem lies in the ion beam polishing, the ion beam polishing equipment made by our R&D center polishes the optical lens processed by the CNC optical machining center, and the optical lens can only reach the peak and valley value of 1 nanometer surface accuracy and the surface roughness of 200 picometers, which is a full order of magnitude worse than that processed by Chase." ”

"The gap is a bit big!" Su Zhe nodded.

"This ion beam polishing technology is simple to say, that is, to bombard the surface of the optical lens with an ion beam, but the trick is that there is no way to determine the material composition of the ion beam, so you can only keep trying." Fan Xiaoming shook his head and said.

Traditional ion beams use inert gases such as argon and nitrogen, but such ion beams do not meet the accuracy requirements.

"Got it!" Su Zhe thought for a while and asked one after another, "Isn't this ion beam polishing technology very valuable?" Millions or tens of millions? What knowledge is needed to develop ion beam polishing technology? ”

"Of course, it's worth the money, as long as you get the ion beam polishing technology, not to mention 100 million, even if you sell 1 billion, some people will buy it, you know, high-end optical lenses are not only used in high-end lithography machines, but also photography, measurement, microscopes, medical, planetariums and many other high-precision fields." Fan Xiaoming stood up, "As for the knowledge that needs to be mastered in research, mathematics and physics can reach the doctoral level. ”

Su Zhe was itchy to hear that ion beam polishing technology was so valuable, but he also knew that he didn't have the level of a doctor, so he couldn't participate for the time being.

He asked, "Doctor?" Brother Xiaoming, aren't you studying for a master's degree? ”

"That, I'm not an ordinary master's degree, besides, I sent five SCI papers for my master's thesis, and the graduation defense has been completed, and in another month, I'm going back to Lingzhou Institute of Technology to participate in the master's graduation ceremony, and then I will enter the doctoral program in September, to put it mildly, if I don't have high requirements, I will graduate with a doctorate." Fan Xiaoming patted his chest and said.

"And what are you doing now?" Su Zhe was a little puzzled.

"Now I help my supervisor do research, and in a few months, I can call my supervisor brother, no way, my doctoral supervisor is Academician Wang Xiuqi, the current supervisor." Fan Xiaoming sat down and said with a smile on his face.

"The doctoral supervisor is actually an academician, and the mentor of the supervisor is your mentor, this relationship is chaotic...... Is your PhD still at Lingzhou Institute of Technology? Su Zhe was a little envious.

"Of course, my doctoral supervisor, Academician Wang Xiuqi, is a professor at Lingzhou University of Technology, dean of the School of Physics, and vice president of Lingzhou University of Technology......" Fan Xiaoming was a little proud, "Xiao Zhe! You can consider Lingzhou University of Technology, I admit that there is a little gap between our school and Qing University and Yan University, but it is not big, and it will definitely not bury your talent. ”

"I'll think about it." Su Zhe nodded.

It makes sense that so many champions flock to Qingda and Yanda every year in the country.

Not to mention those who have and don't, Qingda and Yanda are really strong in academics, and they are definitely top compared to other universities in China.

"Xiao Zhe! For geniuses like us, there is no difference between choosing Qingda University, Yanzhou University or Lingzhou University of Technology, what we need is freedom, the freedom to choose majors, the freedom of study time, the freedom of bachelor's, master's and doctoral degrees, and so on. Fan Xiaoming said half-truthfully.

In his opinion, once Su Zhe chooses Lingzhou Institute of Technology, he is afraid that he will not be able to change it.

"Lingzhou Institute of Technology is so good? So free? Su Zhe looked at Fan Xiaoming with some suspicion.

Fan Xiaoming coughed and said affirmatively: "I don't know about Qingda and Yanda, we Lingzhou Institute of Technology, as long as you are good enough, you can give you what you want, of course, within the framework of the law." ”

"I'll look back and think about it." Su Zhe remembered about the course, "Brother Xiaoming! Can you get the curriculum of science-related majors at Lingzhou University of Technology, preferably with bachelor's, master's and doctor's degrees. ”

"Yes! Absolutely! I have sent you all the courses in science, bachelor's, master's and doctoral degrees, but this course was four years ago, and now it is not open to the public. Fan Xiaoming said and operated it on his laptop.

"Yes! Thank you, Brother Xiaoming. Not long after Su Zhe finished speaking, he received a document from Fan Xiaoming.

"No thanks! You are my sister's student, the stronger you are, the more my sister has the capital to brag, think about it, you have made major achievements in the future, become an academician, won the Nobel Prize, my sister has a light on her face. Fan Xiaoming said with a smile.

"Ahh That's it! Then I'll work hard and win seven or eight Nobel Prizes. Su Zhe said seriously.

"Xiao Zhe! Your heart is so big! ”
