Rekindle 2003

Chapter 722 Teacher, do you have anything to say to me?
In the computer room of the School of Microelectronics of Huating Jiaotong University, Xin Kaiyuan looked at a hot post that appeared in the forum on the screen. After saying "I like it", he picked up a pack of cigarettes on the table and stood up to distribute them to his brothers.

But what surprised him was that, as if by chance, many people stood up in the computer room, all seeming to be spreading smoke.

"Lao Xin, take one!"

Taking Ashima from Luo Kaishun in a funny way, Xin Kaiyuan and a few friends walked to the door of the computer room.

Emmm...

There are still many people walking out.

Then they looked at each other, with knowing smiles on their faces.

"Who wrote that paragraph? You're so talented!"

"It's Mr. Xiaoqing."

"how do you know?"

"That ID is called 'Qing·Yun Danfengqing'. Mr. Qing's vests are all easy to recognize."

"If it's company-related matters, Mr. Xiao Qing's ID is 'Qing Yunyao Yanhuang'.

If it's Bagua forum, he will use "Qing·Yundanfengqing", sometimes he will also use "Qing·Yunmanmanman", "Qing·Yunxicaiwei" and "Qing·Yunong" Qianying' and 'Qing·Yunjian Shenyue' are all officially certified. "

"Emmm... Tell me, does it mean that when Xiaoqing is with a girlfriend, he uses the corresponding ID, and when he is alone, he uses 'Yun Dan Feng Qing'."

"It's possible! But it's none of our business! Don't think too much about it. We can't envy this kind of day."

"But having said that, I have to say that the number one scholar is the number one scholar. There is no one else with this little essay. It makes me want to run out and buy two more packs of cigarettes right now."

"Give me a pack, I happen to have none."

"I must memorize this little essay! From now on, if my girlfriend accuses me of smoking, I will recite it to her righteously!"

Listening to the conversation of the group of students in the corridor, Cheng Jin, who was passing by, frowned and went back to his office with a sullen face.

While the computer was on, he lit a cigarette, walked to the window, took a puff, and stared at the campus through the smoke, dazed.

I don't think about anything, and all the thoughts are poured into my mind.

numbness.

Naturally, his computer had not been turned on for long, and a familiar sound of booting music came, making him sigh, hold a cigarette and sit back down.

After typing on the keyboard for a while, Cheng Jin looked at the blue and white porcelain picture on the Yanhuang Group's homepage on the computer and remained silent.

The cigarette he had only taken one puff in his hand burned to the butt. Cheng Jin sighed and lit another one.

However, he still didn't twitch. He pinched his eyebrow area between his right thumb and index finger and kept kneading it.

The trouble is big.

He just came back from a meeting at Hanxin Company.

It's a shareholders' meeting.

This meeting has only one theme.

How to physically operate Hanxin, turn pilot testing into production, and quickly increase production capacity to successfully accept the order of 100 million DSP chips from Yanhuang Group.

While sitting in the conference room, Cheng Jin realized that he was really going to die this time.

Originally, he didn't realize this.

During the Yanhuang press conference, Cheng Jin was really panicked. Where could he have so many chips to deliver?
Rubbing the chips by hand tests the skill of the master mason.

The decoration company he was looking for had only one master with this skill in the entire company.

As for a chip, it takes more than half a day to rub it by hand.

As for the amount of 100 million, he would rub it with his hands until he could not get it out until he died.

You can’t open a decoration company by yourself, right?

So at that time he wanted to find that cheap student, hoping to dispel his idea.

But when he walked out of the Yanhuang Group, he suddenly came to his senses.

I got distracted.

Wouldn't it be enough if he didn't accept this order at all?

For this reason, he also thought of a way to say it, that is, to confess to Qingyun that the chip was not perfect yet.

What's too high a calorific value, what's unstable, just make it up randomly.

After all, it is just Hanxin No. 1. The first generation chip has some flaws, which is normal.

He had already thought about it. He would deal with it coldly for a few days and wait for ten days and a half. When the publicity was over, he would talk to Qing Yun about it.

At that time, it is nothing more than persuading Qingyun to use foreign chips first, such as chips pulled by motorcycle mules, and speed up the research and development of Hanxin No. 2. By then, Yanhuang Group will use mature chips.

As for whether it can be developed... scientific research always fails.

In other words, with the support of this cheap student’s scientific research funding of at least 100 million per year, it is not impossible to truly reverse-restore Hanxin by yourself.

After all, he is just copying cats and tigers. Over the past few years, he has almost mastered the technology.

This way of saying that one can advance, attack, retreat or defend made Cheng Jin very satisfied with his wit.

But something happened that he never expected.

That cheap student had so much fun!

The posters one after another directly aroused public opinion even more.

Sometimes, Cheng Jin even thought to himself, how great it would be if there really was Hanxin!

But if it were just these warm-up posters, he wouldn't feel like the sky is falling like he does now.

What really made him fall into despair was that he forgot that Qing Yun was not a scientific researcher or an academic, but an entrepreneur.

Qing Yun's operation was not at all what he had imagined before. It was a discussion between academics and academics. Instead, he directly placed the order.

Cheng Jin also forgot that he is not only the dean of the School of Microelectronics of Huating Jiaotong University and the director of the National Microelectronics Laboratory, but also an individual shareholder of Huating Hanxin Semiconductor Company, the commercial operation platform of Hanxin.

Huating Hanxin Semiconductor was established by three shareholders.

Among them, he invested 45, Huating local shareholding platform Huating Zizhu Venture Capital Co., Ltd. invested 64.3, and Huating Jiaotong University shareholding platform Huating Zichen Information Technology Co., Ltd. invested 255 million.

The legal representative is Fu Yuxi, dean of the School of Software of Huating Jiaotong University.

In this shareholding structure, he, as an individual shareholder, only holds 12.35% of the shares, while state-owned assets account for as high as 87.65%.

Therefore, at the shareholders' meeting, his opinions are not important at all.

The state-owned assets department unanimously agreed that this was a pie from the sky and had to be caught. The shareholders' meeting ordered him to immediately start industrial operations, and state-owned assets also stated that they would dispatch a professional management team to help him successfully complete the commercialization of Hanxin Semiconductor.

Now, Hanxin Semiconductor, which was originally a shell company, will immediately start operating as a physical entity...

It was a no-brainer to let him be the general manager and be responsible for the operation, but the other managers of state-owned enterprises, especially the financial director, must have been dispatched by the state-owned enterprises, and he could not hide his tricks in the end.

At this moment, Cheng Jin was panicking.

This is like being roasted on the fire.

Until nightfall, Cheng Jin continued to sit there, the ashtray on the table full of cigarette butts.

After a long time, he sighed, took out his cell phone, and called the cheap student.

"Xiao Qing, bring your latest book to my office at Minhang Campus tomorrow morning. I'll check on your progress."

Cheng Jin believes that to untie the bell, one must tie the bell.

As long as Qing Yun is dealt with and asked to cancel the order, the crisis will be resolved by itself.

Without orders, there would be no economic benefits. He had every reason to propose not to support idle people and postpone the dispatch of personnel from state-owned assets.

then……

Cheng Jin smiled.

Crisis, crisis, crisis brings opportunity.

As long as he adjusts his words tomorrow so that Qing Yun thinks that the product is defective and cannot be commercialized due to lack of money.

As for whether he would betray someone later, he didn't bother to think about it.

all will be good.

Besides, with money and people, it is not impossible to carry out a real reverse restoration project.

After putting out his cigarette, Cheng Jin packed his briefcase and rushed home.

My son is at an age that even a dog would be disgusted with when he is three or four years old. His wife cannot control him, and she cannot control him well.

Compared to himself, Cheng Jin felt that his son was even more of a genius. At only four years old, he could already solve quadratic equations of one variable.

He even felt that as long as he was well educated, it would be absolutely fine for his son to at least surpass his cheap disciple academically.

Although Qing Yun is talented, Qing Yun has only been in the cold for ten years and lacks accumulation.

But he comes from a scholarly family of several generations. He has been enlightened since he was three years old. Even if his talents are about the same, he is definitely a crushing existence.

but……

Cheng Jin, who was driving the car, also had a bitter taste in his mouth. How could his cheap disciple only have academic talent...

……

"What are the characteristics of electronic devices made of semiconductor materials compared with traditional vacuum electronic devices?"

Facing Cheng Jin's question, Emperor Yun blinked his eyes and answered quickly,

“Semiconductor materials have good frequency characteristics, small size, and low power consumption, which facilitates the miniaturization of integrated circuit products. In addition, they are also particularly outstanding in terms of strength, earthquake resistance, and reliability.

However, it is inferior to vacuum devices in terms of distortion and stability. "

"What is a general model of a communication system?"

“Information source, transmitting equipment, channel, noise source, receiving equipment, and information sink.

For electrical communications, the message must first be converted into an electrical signal, and then the signal is sent into the channel through the sending device. At the receiving end, the receiving device is used to amplify and inversely transform the received signal, and then send it to the sink. Convert to original information. "

Qing Yun's answer made Cheng Jin nodded and continued to ask, "The key point is what is the source of information."

"The information source is to convert the transmitted message into the original electrical signal. The signal output by the information source becomes the baseband signal. The baseband signal can be divided into digital baseband signal and analog baseband signal. The corresponding information source is also divided into digital information source and analog information source. ”

According to Qing Yun's learning progress, Cheng Jin asked several more basic questions one after another. Seeing that he answered fluently, he was quite satisfied.

This student is different from other students. Studying is only a small part of life for him, but he has such a firm grasp of the basic concepts, which shows that he has really taken the time to put in a lot of effort.

"Xiao Qing, is there anything you don't understand during the learning process?"

When Qing Yun heard this, he was not polite. He opened the textbook he brought and pointed to a passage and asked,

"Teacher, what is a random process and why should we introduce it?"

Cheng Jin took the book and read it, shaking his head helplessly, "Domestic teaching materials...sigh..."

He sighed and continued, "A random process is a process that changes randomly over time. Remember, it cannot be described by an exact function of time.

You can either understand that a random process is the set of all sample functions, or you can understand that a random process is a set of random variables at different moments in the time process.

Since the information source, noise and signal transmission characteristics in communication all change randomly, they can all be described by random processes.

Then their digital feature descriptions include mean, variance, and correlation functions, and the mean describes the swing center of the sample function..."

Cheng Jin spoke in detail, while Qing Yun recorded it quickly.

One of the characteristics of Huaguo University’s textbooks is that most of the textbooks themselves don’t speak human language.

Moreover, the concept and definition are very unfriendly, and the professor needs to summarize it from the book. At this time, the professor's courseware must be combined.

"Teacher, why do we usually study generalized stationary random processes?"

Cheng Jin smiled upon hearing this, "Because most of the signals and noise encountered in communication systems can be regarded as stationary random processes, studying stationary random processes is of practical significance to you undergraduates."

As he spoke, Cheng Jin flipped through the textbooks Qing Yun had brought. Judging from the creases in the book, this boy was indeed progressing very quickly.

Moreover, what made him feel a little incredible was that Qing Yun, the model with the highest failure rate, had no problems at all. On the contrary, the most problematic thing was relatively simple communication.

Cheng Jin's question made Qing Yun chuckle, "Teacher, have you forgotten that I am also the chairman of Yanhuang Group. This status allows me to find corresponding personnel in the company to answer my questions.

However, in terms of communications, the company's experts are in Jincheng, which is not so convenient. "

This answer made Cheng Jin laugh.

Yes, this kid has an unparalleled advantage over other students when learning these things.

Not to mention asking questions, even if Qing Yun wants to do an experiment or even encounters a difficult problem in the textbook, he can directly perform practical operations to get the answer, without the need to simulate this step.

After answering a few more questions, Qing Yun closed the book and smiled.
"Teacher, I've finished asking my questions. Do you have any more questions to ask me?"

Having said this, Qing Yun sat there and looked at Cheng Jin intently, "In other words, teacher, do you have anything to say to me?"
