In 1978, I was admitted to Harbin Institute of Technology

Chapter 60 Do you think I’m a big shot in nuclear submarines? Just give me a picture?

"…Finite element analysis is very simple. To use it proficiently, all you have to do is remember to replace the original continuous body with a finite set of discrete units."

"Remember the steps: first split, and establish the unit stiffness matrix [K]e (the superscript of e cannot be used) through unit analysis; then combine the unit stiffness matrix into the structural stiffness matrix [K] to form the equivalent node load P; finally solve the comprehensive equation K△=P, and calculate the internal force and stress of the structure by finding the node displacement △."

Liang Hongbin wrote and spoke at the same time.

The students below already had confused looks in their eyes.

No one gave up. Everyone was taking notes frantically. The whole class, when faced with a teacher who was cramming things into their heads frantically, knew that it would be difficult to remember and digest everything completely during class time. So, under Mo Lingyu's arrangement, the class was divided into several groups, with different people taking notes of different content, which were then combined at the end.

Otherwise, you won’t be able to remember it all.

Throughout the entire class, only Xie Wei could barely keep up with Liang Hongbin's pace.

Liang Hongbin often cast his eyes on Xie Wei.

"Today's class ends here. If you have any questions, you can come to my office to find me. Xie Wei, come out with me."

After Liang Hongbin finished the class, he picked up the lesson plan and walked out.

"..."

Everyone who was taking notes quickly looked towards Xie Wei.

"Class monitor, you must tell the teacher to stop stuffing our brains with such inadequate capacity with this advanced knowledge!"

Mo Lingyu whispered to Xie Wei with hope on his face.

Xie Wei glanced at her.

Ah!
woman.

In the entire class, Mo Lingyu was probably the only one who took the most complete notes, and he even understood most of what was said.

He stood up silently and chased after Liang Hongbin.

He didn't know why Liang Hongbin was looking for him, but Xie Wei was sure that it was definitely not to ask him whether he understood the class.

Along the way, Liang Hongbin didn't say a word, and Xie Wei could only follow silently.

Arriving at the school building, he followed into Liang Hongbin's office. Before Xie Wei could speak, Liang Hongbin took out a document from the drawer and handed it to Xie Wei, "Take a look at this."

Xie Wei took the document and was shocked when he saw a photo on the surface.

I began to wonder: Why did Liang Hongbin show me this information?

TAR-224!

In the early 70s, AVCO developed a spy radio for the CIA. It has a compact structure and excellent performance, covering all frequencies from 2 to 24 MHz. The receiver has a variable frequency oscillator (VFO) that can continuously tune all 4 frequency bands.

The transmitter is crystal operated.

Very familiar, but Xie Wei couldn't say it.

"Radio station?"

"Yes, the radio. The principal took great pains to get it. I hope you can make it..."

Liang Hongbin nodded.

"Just based on a photo? No technical indicators? No performance requirements?"

Xie Wei looked at Liang Hongbin in disbelief. The other party thought he was an expert in nuclear submarines in the country!

They can build a nuclear submarine based on a blurry photo in a newspaper, and I can build a communications radio based on a picture?

It's noisy.

Besides, why is it me?

"That's not right, Mr. Liang. Radio is the job of the Radio Engineering Department. I'm not a radio major."

"Radio Engineering is a branch of Physics. This is your final exam in Physics."

Liang Hongbin said calmly.

Xie Wei refused without even thinking about it.

Before he could speak, Liang Hongbin added, "Don't make excuses saying you don't understand. You just returned to Hongguang Factory not long ago, and you have been tinkering with radio for a while, and you have obtained a lot of radio materials from the provincial library."

"..."

What else can Xie Wei say?
He didn't even know what the original owner had experienced before.

Many memories have become blurred.

Du Guowang's words last time made Xie Wei realize that the school had investigated his past very clearly.

Even though he had no memories, he couldn't speak.

The more you talk, the more problems are likely to arise.

"Mo Lingyu used to be a communications soldier and a technical backbone. She is very familiar with communications radio stations. You can work with her. Here are the technical data of Si Erwa and Da Bayi..."

"Teacher Liang, it's definitely not possible for just Mo Lingyu and I to do this."

Xie Wei was helpless.

He could directly come up with a complete and more advanced military communications radio design.

But the problem is that Liang Hongbin suddenly showed up without any warning!
Dare? "The radio engineering department will cooperate. Don't expect to get too much from them. There are more important tasks over there, and the basics of the workers, peasants and soldiers are clear."

"Military? Civilian?"

"Is there a difference?"

"For military use, we have to consider signal transmission in complex terrain, communication quality, standby time, waterproof and dustproof, concealment, etc. For civilian use, as long as the transmission distance is long and the signal transmission and reception are stable, it doesn't matter if the size is bulky and the energy consumption is high."

Now that I know the truth, I don’t bother to pretend anymore.

"It's for military use and needs to be kept secret. You can use my office and go to the radio lab. If you're busy, someone will bring you food."

"..."

As for feelings, Liang Hongbin never considered what would happen if he refused.

"Principal, isn't it inappropriate to let Xie Wei work on radio?"

After Xie Wei left, Liang Hongbin went to the principal's office to report the situation and asked Li Rui in confusion.

The radio project was given to Xie Wei on the orders of Principal Li Rui.

"Don't understand?"

Li Rui raised his eyebrows, "That's right, you don't understand! I don't understand it either!"

"..."

"Don't look at me with such resentful eyes. I get goosebumps when I see that look from you."

Li Rui sighed, "The radio project was arranged by an old man that Xie Wei studied with in Rongcheng. I was even scolded because of Xie Wei."

"???"

Li Rui was scolded because of Xie Wei?
"The old man said that Xie Wei has a leaping mind and many of his ideas are constructive. With Xie Wei's score, Tsinghua and Peking University would not have let him go. If someone hadn't called and stopped him from going to Tsinghua and Peking University, Xie Wei would not have been able to come to our school. We have excellent talents, but we don't know how to cultivate and utilize them..."

"..."

A big shot who can influence the admissions of Peking University and Tsinghua University!
Liang Hongbin suddenly didn't want to ask who the old man was.

"Give the radio a heads-up. This is just the beginning. Whether some of the school's majors can be restored and enroll students as soon as possible depends on how fast Xie Wei can get things done."

Li Rui's words once again stunned Liang Hongbin.

Whether the school can resume enrollment for its majors has anything to do with Xie Wei?
When did Xie Wei become so important?

"I was scolded for this! The old man also said that Xie Wei is a talent in military industry. Here, he is engaged in detergent and CNC. It is a waste to use his talent in improper directions. We should give him a military technology project..."

"We have to have that too!"

Liang Hongbin came out of Li Rui's office with mixed feelings.

It’s a pity that Xie Wei can’t specialize in physics!
"Wu Tao, Xie Wei's father will be at the train station tomorrow morning. Arrange your work and ask Tan Heping to go with you to pick him up. Oh, and ask Wang Zheng to come along, he knows someone."

After Liang Hongbin left, Li Rui asked Wu Tao to pick up Xie Jianguo at the train station tomorrow.

"Xie Wei's father? Should I go and pick him up with Director Tan?"

Xie Wei’s father is a leader?
Seeing Wu Tao's unwilling expression, Li Rui glared at him and said:

"Xie Wei's father not only gave money to the school, but also sent a talent that was snatched from the junior class of USTC!"

"Don't worry, leader. We will ensure that the task is completed."

The reluctance on Wu Tao's face disappeared instantly.

After coming out of Liang Hongbin's office, Xie Wei, holding the documents, kept wondering why Liang Hongbin suddenly gave him the radio station.

There are no technical indicators.

There are no performance requirements.

No funding...

No matter how hard I tried, I couldn't find any relevant memories in my mind.

However, he remembered some of the radio basics and technical information that the original owner had borrowed from the library.

"How is it? What did Teacher Liang say?"

When Xie Wei returned to the classroom, Mo Lingyu leaned towards Xie Wei with a gossipy look on his face.

Xie Wei moved aside awkwardly.

Although the other person is a beauty, she is in public.

There is only one physics class in the morning, and the students who are not going to the laboratory are now studying on their own.

The classmates looked at Mo Lingyu's actions with strange expressions, and those around him pricked up their ears.

"Are you free? Let's go out and talk."

Xie Wei was thinking about the radio and didn't pay attention to the reactions of his classmates.

Go out and talk...

Mo Lingyu's face turned red instantly.

The other students' eyes widened suddenly: He is worthy of being the class monitor, making an appointment with the deputy class monitor, so direct!
