When will I have a long tassel?

"China's technology is of course not as good as foreign countries." Xiao Wenjun said decisively. After that, she changed her statement, "It should be said that compared with more than ten years ago, the gap between us and foreign countries is very small now. The gap in most areas has narrowed to within generations, which is already a remarkable achievement.

"As far as machine tools are concerned, in terms of mid- to low-end machine tools, our domestic machine tools are no worse than foreign ones. If we compare them at the same price, our machine tools are even better than foreign ones. Nowadays, knowledgeable companies are willing to buy domestic machine tools and spend money Less, the performance and quality are similar, and the after-sales service is more convenient.

"In terms of high-end machine tools, the gap between us and foreign countries is still relatively obvious, especially for high-precision machine tools. We are still blank on many models. However, there are also some models that we have done better than foreign countries."

"Yeah, Professor Xiao summed it up well." Tang Zifeng flattered him, and then asked: "So, according to Professor Xiao's opinion, how long will it take for domestic high-end machine tools to be on par with foreign countries? To what extent?"

"It depends on how you define this." Xiao Wenjun said, when discussing issues, she is very particular about logic and meticulousness, unlike Tang Zifeng, who has no formality.

Tang Zifeng said: "I think there should be three levels. The first level is to be able to achieve import substitution, and foreign countries cannot choke our necks; the second level is to be competitive and have its own advantages and disadvantages with foreign products; the third level Just crush them all, go your own way, and leave others with no way to go.”

Xiao Wenjun curled her lips. The last level Tang Zifeng said was so arrogant that she had to express her contempt. However, Tang Zifeng had said similar words to her more than dozens of times, and she was more or less affected by it. When thinking about problems, she would inevitably take the third level as the goal.

"At the first level, I estimate that five years should be enough." Xiao Wenjun replied, "Some time ago, we did a study and found that our country is on the verge of breakthroughs in many high-end machine tool models. Five years will be enough." It won’t be a big problem if it takes time to reach a level that can replace imports.”

"Xiaohui also reported this situation to me. She said that several machine tools developed by the 04 project team are stuck at several emergency nodes. Once they break through, there will be no obstacles behind them." Tang Zifeng said.

Xiao Wenjun nodded, and then said: "The second level you mentioned, I estimate it will take fifteen years. By around 2020, we will have reached the world's advanced level on some models, and will be slightly inferior to others. Each has its own unique pattern, and there is great hope. As for the third level, this is a question for you liberal arts students to think about, and I can’t answer it.”

At the end of the sentence, Xiao Wenjun laughed. Their family is a typical family that combines liberal arts and science. Tang Zifeng is a very pure liberal arts student, and his way of thinking is completely different from Xiao Wenjun.

Xiao Wenjun initially looked down upon liberal arts students, thinking that liberal arts students could just talk the talk without any real ability. After being in contact with Tang Zifeng for a long time, Xiao Wenjun gradually discovered that the way of thinking of liberal arts students also had its merits. At least when analyzing social problems, Tang Zifeng could see more clearly than she, a pure science student.

For example, the third level mentioned by Tang Zifeng, that is, one day China's machine tool technology can develop to the level of crushing Western countries, in Xiao Wenjun's view, it should be unrealistic. Think about it, Western countries have hundreds of years of technology accumulation, and Western machine tool giants have a large number of patents. Xiao Wenjun and others use any formula at will, and they are all named after Westerners. If China wants to replace the West, Even to the point of crushing, how is that possible?

Indeed, China has developed rapidly in recent years, but don’t Westerners develop? You develop quickly because others have already explored the path for you, and you just need to follow it. When you catch up to the forefront, there is no ready road ahead. Everyone encounters the same difficulties. Why can you do better than others?

But the experience of the past ten years makes Xiao Wenjun feel that Tang Zifeng's prediction seems to be reasonable. Ten years ago, Xiao Wenjun could not have imagined that China would have such achievements today.

As far as Xiao Wenjun's research field is concerned, ten years ago, her mentors were still studying foreign literature diligently. The research done by foreign scholars was simply a fantasy for domestic scholars. At that time, articles from China rarely appeared in top international academic journals. When domestic scholars went abroad to attend academic conferences, they were only qualified to sit in and observe, and rarely had the opportunity to speak.

But in just ten years, the situation has changed dramatically. Nowadays, not to mention Xiao Wenjun herself, it is no longer uncommon for her doctoral students to publish articles in top foreign publications. Some highly influential academic conferences have also begun to be held in China. It is also a very common scene for Chinese scholars to stand on the podium and talk rhetorically, while a group of foreigners sit below and listen attentively.

Why is there such a change?

It is difficult to explain Xiao Wenjun's knowledge structure. It is true that Chinese scientists work very hard, but foreign scientists also work very hard. Why do China's achievements continue to increase?

In response to such problems, when she went to a gathering of Tang Zifeng, Wang Zijie, Liang Zile and others, she found that these liberal arts students were not surprised at all.

"Social demand is the driving force behind the development of science and technology. Once society has a certain demand, this demand will promote the development of science and technology more than ten universities."

This is what Wang Zijie said, but it is said that he quoted the original words of a great man.

China is currently the country with the fastest growth rate in the world. The added value of China's manufacturing industry will soon surpass that of the United States and become the country with the highest added value of manufacturing industry in the world. As the world's factory, China has the largest demand for machine tools in the world, and this demand will promote the rapid development of machine tool research.

This is the conclusion of liberal arts students.

Of course, this is just the conclusion of the group of liberal arts students around Tang Zifeng. Qimudeng is also considered a liberal arts student, and his conclusion is exactly the opposite, and this opposite conclusion also has some market nowadays.

Xiao Wenjun conducted literature research with this conclusion, and was surprised to find that in the past few years, machine tool research in the old Western industrial countries has been declining, while research in China has shown a spurt of growth. In many subdivided fields, there has been no new progress in Western countries for many years. On the contrary, Chinese scholars have been intensively cultivating these fields and have achieved repeated results.

Just now at the Laosen Machine Tool Technical Service Center, Ferguson also expressed a similar view. He claimed that he could find various technical inspirations in Gaotan Park, which were generated from production practices. Without production practices, no matter how talented a scholar is, he would not be able to produce innovations.

Perhaps, the third level mentioned by Tang Zifeng, that is, the situation where Chinese machine tools completely crush the West, is indeed possible to achieve, although Xiao Wenjun cannot estimate when this day will come.

"I plan to go back and report to the leaders. In the name of our Tsinghua Mechanical Department, we will open a machine tool technical service center in Gaotan Park. Like Ferguson and others, we will specialize in undertaking research and development projects entrusted by enterprises in the park. By the way, we can also sell our The technology developed in the school uses corporate money to support our subsequent research and development."

Xiao Wenjun brought the topic back to the topic and said to Tang Zifeng.

"I completely agree." Tang Zifeng said, "In fact, you should have done this a long time ago. The need to combine scientific research with practice is the simplest principle."

"Why didn't you tell me earlier?" Xiao Wenjun choked.

Tang Zifeng smiled and said: "Weren't you still pregnant with the child at that time? I'm afraid that as soon as I say it, you will come to Linhe regardless. I'm not worried about anything, but my dad, my mom, and your dad Your mother, can you let me go?"

"Selfish!" Xiao Wenjun scolded, but she also knew that Tang Zifeng was right. She was pregnant with a child before, and if she really came to Linhe to set up a technical service center, the elderly people on both sides would definitely not agree. Now that the child can walk, it won't be a big problem if she comes to Linhe again.

"If they knew you were coming, Linhe City Government would probably be crazy with joy. Even if you ask Linhe City to give you rent exemptions, tax exemptions, etc., there will be no problem. What you are holding in your hands is a piece of gold. As a signboard, Linhe City’s popularity in the country will increase by several percentage points because of your presence.”

Tang Zifeng laughed and gave Xiao Wenjun advice, and sold Linhe City without hesitation.

Of course, he also knew that the Linhe Municipal Government was very willing to be betrayed by him. If it could attract Tsinghua University to build a production and service center in Gaotan Park, even if it was just an empty center with a sign, the Linhe Municipal Government would be willing to spend the money. High price.

Xiao Wenjun didn't appreciate it. She said: "rent, taxes, etc., inevitably don't mean much to us, and we don't care about this little money. The most important thing is to start business as soon as possible. I don't want us to After the service center is established, it will help your park enterprises solve trivial problems every day. It is best to have some relatively major technical problems with particularly significant economic benefits and theoretical value."

"I'll take care of this." Tang Zifeng clapped his chest loudly, "We don't have anyone else in Linhe. When it comes to major machine tool technical issues, I have as much as I want, but I'm afraid you won't be able to eat it."

"Really? Why didn't I see it?"

"Look at your husband's face, don't I look like a troubled boy?"

"Are you convinced that you are a teenager and not a child?"

"You also have problems in childhood. Su Hua has been waiting for you in Linhe for seven or eight days. If his problems are solved, it will be enough for you teachers and students to publish 20 papers."
