"China's technology is certainly not as good as that of foreign countries. Xiao Wenjun said categorically, and after that, she changed her words, "It should be said that compared with more than ten years ago, the gap between us and foreign countries is already very small, and the gap in most fields has been narrowed to within generations, which is already a very remarkable achievement."

"As far as machine tools are concerned, low-end machine tools, our domestic ones are not worse than foreign ones, if it is the same price to compare, our machine tools are even better than foreign ones. Now knowledgeable enterprises are willing to buy domestic machine tools, spend less money, performance and quality are about the same, and 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 high-precision machine tools, and many models we are still blank. However, there are also some models that we have done better than foreign ones. ”

"Well, Professor Xiao summed it up well. Tang Zifeng slapped a sycophant, and then asked: "So, in Professor Xiao's opinion, how long does it take for domestic high-end machine tools to reach the level of keeping pace with foreign countries?"

"Look how you define this, go hand in hand. Xiao Wenjun said that when discussing problems, she is very logical and meticulous, unlike Tang Zifeng.

Tang Zifeng said: "I think it should be three levels. The first level is to be able to achieve import substitution, and foreign countries cannot hold our necks; the second level is to be competitive and have their own advantages with foreign products; and the third level is to comprehensively crush and go our own way, so that others have no way out. ”

Xiao Wenjun pursed her lips, the last level that Tang Zifeng said was really a little arrogant, so she couldn't help but express her contempt. However, Tang Zifeng has said something like this more than dozens of times in front of her, and she has been more or less affected, and it is inevitable to take the third level as the goal when thinking about problems.

"The first level? I guess five years should be enough. Xiao Wenjun replied? Some time ago, we did a study, found that our country is on the verge of breaking through in many high-end machine tool models, and it should not be a big problem to reach the level of being able to replace imports in five years. ”

Xiaohui also reported this situation to me? She said that several machine tools developed by the 04 project team were stuck in a few anxious nodes, and once they broke through, there would be no obstacles behind. Tang Zifeng said.

Xiao Wenjun nodded, and then said: "The second level you mentioned, I estimate that it will take fifteen years, by 2020? As for the third level, this is a question that you liberal arts students think about, and I can't answer it. ”

In the end, Xiao Wenjun laughed. Tang Zifeng is a very pure liberal arts student, and his way of thinking is completely different from Xiao Wenjun's.

Xiao Wenjun looked down on liberal arts students at first, and felt that liberal arts students were nothing more than able to speak in the vernacular, and had no real ability. After a long period of contact with Tang Zifeng, Xiao Wenjun gradually discovered that the way of thinking of liberal arts students also has its merits? At least when analyzing social issues, Tang Zifeng can see it more thoroughly than she, a pure science student.

For example, the third level that Tang Zifeng said, 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, Western machine tool giants have a large number of patents, Xiao Wenjun they use a formula casually, are named after Westerners, China wants to replace the West, and even reach the level of crushing, how is it possible?

It is true that China has developed very rapidly in recent years, but don't Westerners develop it? You develop fast because others have already explored the way for you, and you just need to follow along. When you catch up to the front line, there is no ready-made road ahead, everyone encounters the same difficulties, why can you do better than others?

But the experience of the past ten years made Xiao Wenjun feel that Tang Zifeng's prediction seemed to be reasonable. Ten years ago, Xiao Wenjun could not have imagined that China would have achieved such an achievement today.

In terms of Xiao Wenjun's research field, ten years ago, her supervisors were still studying foreign literature, and the research done by foreign scholars was simply fantastical for domestic scholars. At that time, it was rare for top international academic journals to have articles from China, and domestic scholars who went abroad to attend academic conferences were only qualified to sit down and observe, and rarely had the opportunity to speak.

But in just a decade, the situation has changed dramatically. Now not to mention Xiao Wenjun herself, it is a doctoral student she leads, and it is not uncommon for her to publish articles in top foreign journals. Some influential academic conferences have also begun to be held in China, and it is also a common scene for Chinese scholars to stand on the podium and talk rhetorically, and a group of foreigners to sit down and listen attentively.

Why is there such a change?

With Xiao Wenjun's knowledge structure, it is difficult to explain. Chinese scientists are working hard, this is true, but foreign scientists are also working hard, why are China's achievements increasing?

In response to such questions, when she went to the gathering of Tang Zifeng, Wang Zijie, Liang Zile and others, she found that these liberal arts students were not surprised by this.

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

This is Wang Zijie's words, but it is said to quote the original words of a certain great man.

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

That's what the liberal arts students concluded.

Of course, this is just the conclusion of the group of liberal arts students around Tang Zifeng. Qi Muden is also a liberal arts student, and his conclusion is the opposite, and this opposite conclusion is quite a market nowadays.

Xiao Wenjun took this conclusion to do literature research, and then was surprised to find that in the past few years, the research of machine tools in the old industrial countries of the West is declining, while the research in China has shown a trend of spurt growth. In many subdivisions, Western countries have not made new progress for many years, but Chinese scholars have been intensively cultivating these fields, and the results have been repeated.

Just now at the Laosen Machine Tool Technical Service Center, Ferguson also expressed a similar view. He claims that he can find all kinds of technical inspiration in the Gaotan campus, which are generated from production practices, without which even the most talented scholars cannot produce innovation.

Perhaps, the third level that Tang Zifeng said, that is, the situation of China's machine tools comprehensively crushing the West, is indeed possible to achieve, although Xiao Wenjun can't estimate when this day will come.

"I plan to go back and report to the leaders, in the name of our Tsinghua Department of Mechanical Engineering, to open a machine tool technical service center in Gaotan Park, and like Ferguson, they will undertake research and development projects entrusted by enterprises in the park. By the way, we can also sell the technology we developed in the school and use the company's money to support our subsequent research and development. ”

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

"I couldn't agree more. Tang Zifeng said, "Actually, you should have done this a long time ago, scientific research needs to combine practice, this is the most simple truth." ”

"Why didn't you say it earlier?" Xiao Wenjun choked.

Tang Zifeng said with a smile: "Wasn't you still pregnant with a child at that time? I'm afraid that as soon as I say it, you will run to Linhe regardless of it." I'm not worried about anything, but my parents, and your parents, can they let me go?"

"Selfish!" Xiao Wenjun reprimanded, but she also knew that Tang Zifeng was right, she was pregnant with a child in her belly before, if she really ran to Linhe to set up a technical service center, the old people on both sides would definitely not agree. Now that the child can walk, she will come to the river again, and there will be no big problem.

"If I knew you were coming, the Linhe City Government would have gone crazy. Even if the lion opens his mouth and asks Linhe City to give you free rent, taxes, and so on, it's all fine. What you are holding in your hand is a gold-lettered signboard, and the popularity of Linhe City in China will increase by several percentage points because of your entry. ”

Tang Zifeng smiled and gave Xiao Wenjun an idea, and sold Linhe City without hesitation.

Of course, he also knew that the Linhe Municipal Government was very willing to be betrayed by him, and if it could attract Tsinghua University to build a production and service center in Gaotan Park, even if it was just an empty shell center with a signboard, the Linhe Municipal Government would be willing to pay a 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 money." The most important thing is to get your business up and running as quickly as possible. I don't want our service center to be established every day to help you solve some trivial problems, and it is best to have some major technical problems, and the economic benefits and theoretical value are particularly significant. ”

"This one is on me. Tang Zifeng slapped his chest loudly, "We don't have anything else in the river, when it comes to major machine tool technical problems, how much or how much, I'm afraid you won't be able to eat." ”

"Really, why didn't I see it?"

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

"Are you sure you're a teenager, not a child?"

"There are also 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 send 20 papers. ”
