Rebirth of the Military Industrial Overlord

At 8 o'clock in the morning, Liu Mei finally stood outside the campus in Tainan City, Shandong Province.

Ludong University is the origin university of China’s modern higher education. Its establishment history can be traced back to the "Ludong University Hall" founded in 1901. It is also the second national university established by China after the "Jingshi University Hall". , Has experienced 80 years of ups and downs.

The school gate is not big. There are two marble gateposts standing at the gate. On the right gatepost hangs a wooden sign with black characters on a white background. On the wooden sign is 4 bold and bold characters "Ludong University". Liu Mei looked at the handwriting carefully, and it turned out to be the familiar handwriting of the founding elder.

She walked into the campus, and no one came out to stop the questioning. The campus is different from the research institute. It is a completely open environment. No one will ask questions because of strangers who suddenly appear. The students who passed by in twos and threes were all students holding books and preparing to go to class. Their faces were shining confident and youthful. She stopped a boy who hurried past, asked the address of the physics department, and walked slowly. Away.

The fresh campus air in the morning was mixed with the faint fragrance of sweet-scented osmanthus. Liu Mei couldn’t help taking a few deep breaths, which reminded her of her school days. The girl’s time in ponytails was already in her The memory gradually blurred, as if it had been a century away from her, but today it suddenly became extremely clear, as if it could be reached by a hand.

She laughed self-deprecatingly, and touched her still smooth face. She knew that in the corners where she was not noticed, the corners of her eyes had grown thin crow's feet, and the years were urging, and now she is no longer young.

She took a sigh of relief and calmed her mind. For her, the golden years of a woman’s appearance have passed, but her career has just begun, and all this development depends on what the little evildoer said by Tan Zhenhua People, today, she will find him.

Sitting by the window, Li Wei stared at the professor's blackboard writing on the blackboard, immersed in the ocean of formulas and numbers. He likes these, those complex element combinations, and the profound magnetic curves, outlines a beautiful picture for him, which deeply attracts him, allows him to roam and explore.

Predecessors have already opened part of this picture scroll, but there are still more unknown worlds. He feels that he was born to explore these unknowns. Every time he explores, he will feel like a three-year-old urchin opening a Christmas gift. Packaging always contains surprises, and exploring this whole picture is the mission given to him by God, and he is willing to contribute his life to this.

When the bell rang after class, and other classmates had stood up and packed their books to leave, he was still looking down at his notes, hoping to review the content of the class as soon as possible. This was the secret to his outstanding class results. arms.

Just when he was attentive, a slightly magnetic strange mezzo-soprano sounded in his ears:

"Excuse me, are you Li Wei majoring in magnetism?"

He raised his head and was surprised to find that a strange middle-aged woman stood before him.

This person is well-proportioned and has a serene face. He looks in his early forties, but his eyes seem to have gone through the vicissitudes of life. A thick black hair is randomly tied behind his head, and one or two white silks can be vaguely seen in the black hair. The whole person looks like the big sister of a neighbor’s house, exuding a breath of intimacy, but slightly with the dignity of the superior, like a mother looking at her child, looking at her with a smile. he.

He quickly stood up and returned: "This is Li Wei, may I ask you?"

While Li Wei was looking at Liu Mei, Liu Mei was also looking at him.

Sure enough, as Tan Zhenhua said, this young man has a round face and a pair of black framed eyes. The thickness of the lens is definitely more than 500 degrees. His eyes are not big, but he is very energetic, with a pair of charming ears.

Liu Mei stretched out his hand, shook him gently, and said straightforwardly: "Hello, I am Liu Mei from the Magnetic Materials Factory of the 4014th Research Institute of Ningdu. I am the director of the factory, so I would take the liberty to interrupt. I have some questions to ask classmate Li. Ask, do you have time?"

Li Wei is a little bit inexplicable. Comrade Liu Mei, who came to the door, said that his home was from a magnetic material factory. This is the counterpart of his profession. But if you have any technical problems, you should consult the professors in the department. ? How could you find a student like yourself who hasn't graduated yet?

He asked confusedly: "I have no classes in the next two sessions, so I can talk to you, but I'm just a student. I'm afraid my knowledge and ability are limited. If you have technical problems, you can find the expert teachers in our department. They should be able to help you better."

Liu Mei smiled and said, "Before I came, I knew that you were still studying, and I also knew that you were about to graduate. Someone recommended you to me and said that only you can solve the problem, so I came."

Li Wei touched the back of his head, hesitatingly replied: "Then, okay, I wanted to go to the library, or else, let's talk while walking?"

Liu Mei readily agreed, and when Li Wei packed up, the two left the classroom together.

Liu Mei was not in a hurry to take out Tan Zhenhua’s magic weapon. After all, it was something he threatened to be worth one billion dollars. She wanted to explore the bottom of this Li Wei first, so she asked: "Student Li Wei, let me tell you Before the question, I want to ask you first, do you know about rare earths?"

Li Wei was taken aback, he felt a little strange. Could this scene be a legendary interview?

The word interview was still a fashionable thing in the early 1980s. At that time, college graduates were assigned jobs by the state. Neither the employer nor the graduates themselves had experienced this process that posterity job seekers and HRs were accustomed to. Employers often had to deal with new employees after reporting. The first time my future employees met, they all relied on a file before. And only a few graduates who choose the “three foreign-funded enterprises” that are still completely new will they go through this mysterious process, and their vivid descriptions after returning from the interview have become the after-hours of school students. Of talks.

Of course, Li Wei had also heard of these. He hesitated and replied: "Yes, I have learned this. In fact, rare earth is the collective name of 17 metal element compounds. According to the quality, it can be divided into light rare earths including: lanthanum, Cerium, praseodymium, neodymium, promethium, samarium, europium and heavy rare earths include gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, and yttrium. They have excellent photoelectromagnetic properties, so rare earths have industrial properties. "Gold" is called.

After a pause, he went on to say: "Several developed countries abroad have conducted in-depth research on this material and achieved many results, but our country's application research has just started. As far as my own professional field is concerned, the application of rare earth materials It's also very extensive."

After answering these questions, he thought for a while and added: "Our country has a rich reserve of rare earths, but it is said that the current level of development and utilization is very low. Basically, they are dug out and exported directly, and I heard that they are sold very cheaply. Not only will this not bring much profit, but it will also damage the environment, which is a pity."

Liu Mei nodded with satisfaction. Li Wei’s answer was similar to what Tan Zhenhua had told her. From these simple sentences, Liu Mei at least heard that the student’s basic skills are quite solid, such as combining those 17 Liu Mei I feel that the elements that I can't recognize the characters are so memorized...

So she decided to ask a further question: "Then classmate Li Wei has heard of rare earth permanent magnet materials?"

Liu Mei's question is actually asking about Li Wei's itching.

Because this is what he has been studying recently! His most respected teacher, one of China’s top experts, the founder of magnetism, the founder of the Department of Magnetism of Ludong University, and the director of the Department of Physics, Professor Guo Yicheng is conducting a research on a new type of permanent rare earth Magnetic materials, and he is honored to be one of Professor Guo's assistants, and this is also the direction he chose for his graduation project.

Now that someone asked a question, the young Li Wei couldn't help showing off. He smiled and said, "Director Liu, you are asking the right question. There are several branches of magnetic research. I happened to be following my teacher on a topic about new rare earth permanent magnetic materials. My teacher Guo Yicheng The professor is the most authoritative magnetism expert in China."

When Liu Mei heard this, her spirits came immediately, but she firmly remembered Tan Zhenhua's words that rare earth permanent magnet materials represent the future. So she asked: "What have you studied? Can you say no?"

"This……,"

Li Wei hesitated. Although the progress of this subject is not within the scope of the state's secrecy regulations, he can't casually disclose it to a stranger who meets for the first time.

Liu Mei saw his hesitation, thought for a while, took out his work permit from his pocket and handed it to Li Wei. At the same time, he said: "Student Li Wei, I said when I introduced myself. The magnetic material factory of the 4014th Institute, our institute is a military electronic engineering research institute and the largest radar research and construction security unit in China. Student Li can rest assured about my origins. What I just asked is just to understand your research. You don’t need to tell me if there is any inconvenience in the basic situation of the country, just choose what you can say."

Li Wei took Liu Mei’s work permit and took a closer look. The green cover was gilded with the words “Ningdu 414th Research Institute Work Permit”. After opening it, it was a one-inch standard photo of Liu Mei. It is stamped with a steel seal and a bright red unit seal. In this era when the small "licensing" advertisement has not been covered with telephone poles, this certificate is still very convincing.

He returned the certificate to Liu Mei, thought for a while, and said, "Director Liu, I don't believe you. I am just a student who is about to graduate. I just give the teacher a hand, and I can't say in the research direction. What are you here, I can only tell you briefly about some things I know."

Seeing Liu Mei nodding, Li Wei continued: "Our current main research direction is mainly samarium-cobalt permanent magnets. This kind of permanent magnets began to be studied in our country in the 1960s. Due to the high cost of such permanent magnets, The process is complex and is currently mainly used in the field of military scientific research. Our research mainly hopes to further increase its magnetic energy product and reduce production costs by improving its composition and preparation process. I can't say where the specific progress is."

Liu Mei frowned slightly because the names of the two materials mentioned by Li Wei were really unfamiliar to her, and she remembered very clearly that the future direction Tan Zhenhua told him was that the permanent magnet contained iron!

She asked suspiciously: "You haven't studied iron-containing permanent magnets?"

Li Wei was stunned for a moment, thought for a while, and then asked in confusion, "Ferrous permanent magnets? Mr. Liu, would you not say ferrite permanent magnet materials? That is already a very mature product, and What's worth studying? Are there other iron-based rare earth permanent magnet materials?"

Liu Mei said with certainty: "No, the current product of our factory is ferrite permanent magnet material. I am very familiar with it. It is definitely not this. It may be the iron-based permanent magnet material you mentioned later."

After speaking, she thought for a while, and decided to follow Tan Zhenhua’s statement, so she took out the envelope that had been placed next to her body and handed it to Li Wei, and then solemnly said: "When I came, that point My guy said, he said that only you can see the things in this envelope, and he said,"

Li Wei took the envelope and asked casually, "What else did he say?"

"He said, the contents of this envelope are worth one billion dollars!"

"what!"
