God-level selection: choose the college entrance examination full score at the beginning

The speed of progress is simply monstrous

At this time, Cheng Hao had already entered the laboratory in a white coat.

“Cheng Hao, you came just in time!”

Academician Lin saw Cheng Hao walking into the laboratory at a glance.

“Zhang Ming, give Cheng Hao the data you just collected and ask him to build a function model!”

Academician Lin said to Zhang Ming who was on the side.

Zhang Ming quickly exported all the data from the matlab on the side and handed it over to Cheng Hao.

Cheng Hao didn’t talk nonsense. It wasn’t the first time he had done this kind of thing in the past three or four months. He immediately took the USB flash drive and started on another computer next to him to export the data.

Open Matlab, according to the data, start using Matlab, many different properties of materials, all appear in Matlab, Cheng Hao focused on the data in front of him.

My mind turned rapidly, and I began to quickly process these data into an image function.

These contents are actually the contents of functional analysis, which can also be regarded as a part of computational materials science.

However, computational materials science, at this moment, is basically just a prototype, far from being a discipline, and more of a small branch of functional analysis.

Cheng Hao processed it for a while, and concentrated on looking at the data in front of him.

His brows were tightly wrinkled.

In fact, the function this time is simpler than last time, but the optimal solution this time is more difficult to find than last time, because the materials are more diverse this time.

And it is more sensitive to the data of cost. Last time, the main material was always graphene, and it is not so sensitive to cost.

But this time it’s different. For batteries, cost has always been a huge problem.

Academician Lin frowned, looking at the laboratory next to him.

He walked to Cheng Hao’s side and glanced at the functions on Cheng Hao’s computer.

“How about it?”

Academician Lin asked Cheng Hao.

Cheng Hao pondered for a while, looked at Academician Lin in front of him and said: “From the current situation, the data shows that the copper-aluminum alloy conductive film has the highest efficiency, and the cost is relatively the lowest!”

“Copper aluminum alloy?”

Academician Lin was slightly taken aback.

“What about the specific ratio?”

“Fifty-one percent aluminum, forty-seven percent copper, and then two percent carbon.”

After Cheng Hao glanced at the result of his calculation, he hesitated for a moment, and said to Academician Lin.

“Asen, follow this ratio!”

Hearing Cheng Hao’s words, Academician Lin immediately spoke to Zheng Sen who was operating beside him.

Soon, according to Cheng Hao’s operation, the copper-aluminum alloy was prepared, and then the battery lithium battery was plated with a conductive coating with the help of the instrument next to it.

Soon, the conductive coating was finished, and the battery was brought over for a discharge test.

Not long after, the experimental data came out.

“Professor, the data this time is very stable, and the effect is also very good!”

Zhang Ming on the side had a trace of excitement in his eyes, and said to Academician Lin.

At this time, Zhou Ming also came in from the outside with a map.

“Professor, the data from the X-ray electron microscope have come out.”

Zhou Ming said to Academician Lin in front of him.

Academician Lin glanced at the atlas, then handed it to Cheng Hao in front of him.

“Take this battery and take it to the transmission electron microscope for irradiation.”

Academician Lin said to Zhou Ming.

“Yes! Professor!”

Zhou Ming nodded, and Academician Lin passed the data from the projection electron microscope to Cheng Hao who was beside him.

The experiment lasted for five or six hours, and it stopped when everyone was exhausted.

“Everyone worked hard today!”

Academician Lin clapped his hands with a smile on his face, and said to Cheng Hao and others with a smile in his eyes.

“Our experiment has progressed a lot so far. Basically, we finally have a practical range for the specific ratio of the conductive coating of the lithium-iron battery. The final determination should be fed back to the factory. There, determine which one is more expensive and more cost-effective in the industrial field.

It can be said that nextWhat happened here is none of our business. During this period of time, although the conductive thin film for lithium-iron batteries is a national project, the difficulty of the experiment is not too high, but the repeatability is too strong. actual cost.

However, we finally have a definite scope, and basically completed our task, everyone is lucky! ”

Academician Lin smiled and said to everyone in front of him.

Smiles appeared on everyone’s faces.

At this time, Academician Lin smiled slightly, looked at Cheng Hao in front of him and said: “Student Cheng Hao, your performance this time is very good, this time the special conductive coating for lithium-iron batteries can be directly used as your master’s thesis! ”

Hearing Academician Lin’s words, Cheng Hao’s eyes showed a hint of surprise.

“Professor, I…”

“Okay, there’s no need to say so much.”

Academician Lin looked at Cheng Hao in front of him with a hint of emotion in his eyes and said.

“Although you have only studied with me for half a year, you have already met or even exceeded the standard for master’s degree graduation, although I am also very reluctant to part with you as a graduate student.

But in front of you, there is still a wider world waiting for you to explore. I just hope that you must understand where your heart is! ”

Academician Lin said solemnly to Cheng Hao in front of him.

“I see!”

Cheng Hao solemnly nodded towards Academician Lin in front of him.

At this time, Academician Lin in front of him smiled, and said to Cheng Hao in front of him: “Okay! Go and sort out the papers! It’s almost the end of the term, so just use this paper and the graduates of this year to graduate! Wait!” In the second half of the year, go to Princeton to see more, as a scholar, your vision should not be too narrow, you need a broad mind and vision! Go to Princeton, it’s very good!”

“is teacher!”

Cheng Hao nodded.

Zhang Ming and others around looked at Cheng Hao with envy in their eyes.

But they don’t have any complaints. After all, they have seen the experiment process these days, including the learning process, and Cheng Hao’s level has improved rapidly.

These days, let alone a master’s student, even a general Ph.D. level is probably not as high as my junior student in the field of physics and materials!

Anyway, it’s outrageous. This speed of progress is simply monstrous.

What’s even more outrageous is that Cheng Hao’s level in the field of computing materials, as long as he is given a series of data from material experiments, he can even calculate what step you are in, what materials you add, and what results this material brings. .

Therefore, everyone is not surprised that Cheng Hao graduated early.

Academician Lin looked at Cheng Hao with emotion in his eyes.

Cheng Hao is really the most worry-free graduate student he has ever supervised. Even ordinary doctoral students are not as worry-free as Cheng Hao. His own math ability is extremely strong, even better than himself, and he is very smart.

He even knows the ways of the world very well, and can complete the tasks he assigns very well every time. When he is giving lectures, he can learn by analogy every time, and his learning speed is very fast.

Academician Lin was actually very reluctant to give up Cheng Hao graduating from his master’s degree, but he also knew very well that Cheng Hao had a wider world.

No way, in the field of basic science, the gap between China and the West and the United States is really too big!

This kind of genius can only have a higher platform abroad!

Although I don’t know if classmate Cheng Hao will come back in the end, but thinking about it, Cheng Hao should return to China!

Thinking of this, Academician Lin sighed slightly in his heart.
