Tohoku University is arguably the top university in the three eastern provinces, and from last year's recruitment of preparatory students from all over the country to this year's admission of preparatory students who passed the exam, this institution of higher learning has become bustling with activity. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 Although it is the middle of summer, the wind on the campus is very gentle, the sun is extremely bright, and the green space paved with green and soft turf has always been the favorite place for students to read and rest, but although they do, for university students, they don't have much time to rest, and even when they are eating, they will read books, and they walk much faster than the outside world, which actually has a lot to do with their heavy studies - unlike European universities for three or even six or seven years, Northeastern universities tend to have only two years of study outside of medical school, which means that it takes them two years to complete the coursework that takes three years to complete in Europe and the United States.

The heavy study makes every student at Northeastern University develop the habit of "seeing the seams", that is, squeezing out as much time as possible to study, including walking, and the pace of walking is much faster than that of normal people. Students walk briskly around the campus, holding books in their arms, walking briskly on the roads around the campus, and even running to save time for walking......

However, although it seems that the schoolwork is heavy, for the vast majority of students, they do not feel that it is heavy, which may have a lot to do with the fact that these children, talented and even well-born students are accustomed to private acquaintance and the heavy schoolwork of the college, in the traditional college, usually there are only the first and fifteenth days of the first day of junior high school and the fifteenth day of the month, and they have to study 28 days a month, but here although the schoolwork seems to be heavy. But there is a day and a half off every week. Although, for the vast majority of people. Breaks are also used for schoolwork, which seems to be very comfortable for some students.

For Wu Chaoxun, who has learned English since he was a child and speaks English more fluently than Mandarin, his life is very comfortable and enjoyable, both in college preparation and in college - most of the textbooks in the school are English or German textbooks, and Wu Chaoxun only needs to learn German well. It is enough to solve the problem of attending classes.

But for his friend Wang Yu, foreign languages are his weakness.

"If you don't have a foreign language, that's great......"

Lying on the grass in the campus, Wang Yu, who was basking in the sun, was thinking like this in his heart, but when he was thinking about this issue, he was thinking more about professional issues.

"What the hell am my brain good at?"

Wang Yu has been worried about this problem for a long time. At least he knows what he's not good at. It's just those ordinary courses.

"It's not about what you learn, it's about learning!"

The friend's self-talk made Wu Chaoxun put down the German textbook in his hand and taught him a lesson. This friend of mine is always too frivolous.

"I know. I know it's not okay not to study, but I still hate those ordinary subjects......"

Not only is it difficult to learn foreign languages, but algebra is also a headache for him. I'm still a little interested in geometry. However, for Northeastern University, which implements "all-round education", these are all compulsory subjects.

I still don't want to give up the pursuit of writing textbooks in the future. Now the students at Northeastern University have a common characteristic, which is to be the first in China. If you write textbooks, you will become the number one educator in China.

"Now is an era of great change, and you all have the opportunity to become China's No. 1 ......"

At the beginning of the school year, Dashuai's lectures on campus deeply stimulated every young person in the school, and it is precisely because of this that they will aspire to become the first in China and a pioneer in the industry.

In this era of grass creation, almost every young person thinks so. Although as a student, Wang Yu's foreign language is average, and even mathematics is extremely average, but as a self-proclaimed "son of the times", of course, he also has this ambition vigorously, without a little suspicion or a little discount.

"From now on, new college students will graduate every year, such as the Tongbun College and the vocational school in Incheon......"

Wang Yu said with some annoyance, it seems that he was "late" in school.

"Of course, there are more and more college students, the country's development needs, you see that even the mainland has begun to run universities, maybe, in a few decades, there will be college students everywhere!"

Wu Chaoxun, who was a friend's words, closed the book in his hand and said with a smile.

"But only in an era like now, when college students are very rare, it is possible for engineering students to be sent to preside over factories as soon as they graduate, and medical students can become deans immediately after graduation, in short, we are lucky to be in such an era, and this era will be gone forever."

"That's true, it's a great opportunity for us!"

Wang Yu nodded seriously. As a friend said. When it comes to developing a discipline, people who are in the initial stage are very advantageous, and as long as they introduce this knowledge from abroad to China, they can become Chinese authorities in this field.

"But it seems like we're a little too late."

Wang Yu said as if he had thought of something.

"You see, there are so many people who have graduated from the Faculty of Letters, and many of them have taken on important responsibilities as soon as they graduate......"

In his opinion, those seniors are undoubtedly the luckiest people, they are the first batch of college students in China, so that they have just graduated and taken on a heavy responsibility that is unimaginable to outsiders, just like the railway bridge on the Yalu River, which was not even built by Western engineers, but designed and presided over by the graduates of the civil engineering department of the Tongwen College.

"Hey, there are even people who work as teaching assistants in schools, but I really don't know what's wrong, they actually use English in class!"

Wang Yu's complaint made Wu Chaoxun smile, but no, although they are Chinese, they still use English or German in class, not official dialect, for many students who are not good at foreign languages in private, they will always complain in private.

"I'm afraid the reason is not because they don't have to take classes in the official language, but because there are no textbooks in the national language, and it seems that I still have to learn a foreign language well. In the future, it will be good to write national textbooks! ”

This is a friend's words. Let Wu Chaoxun nod thoughtfully. But a question arose in his mind – what should I do? Is it like my uncle, who studied law and became a lawyer or judge in the future?

Even as the so-called "son of the times", Wu Chaoxun, like many young people, is also full of confusion about the future, maybe for them, the dream was the title of the gold list, or maybe it was the repeated encounters that made them give up the scientific expedition, and when they were affected by Western culture. In the depths of their hearts, all kinds of questions arise in their hearts, and they do not know how to choose the future path, after all, there are too many choices in front of them.

Choice, as early as last year, Zhang Mingwei made his own choice, to a certain extent, although he graduated from the same academy of letters, but he was a handsome student - he worked as an assistant in the studio of the Tongjian Mansion for half a year, and it was that half-year assistant experience that changed him, allowing him to learn a lot of knowledge that was not taught in books.

As a teaching assistant in the Department of Mechanical Engineering. Although teaching students is Zhang's main job, as a teaching assistant, he has more time to devote to research. And this is exactly his choice, and more importantly, he can conduct research with his students, just like the big man did back then.

In the test room, there is a strange smell that is choking, and those who know this smell know that this is the smell of diesel, which is the strange smell and oil smell emitted by the diesel engine when it is running.

In the process of studying the internal combustion engine, the commander had guided him and several classmates to manufacture the V6 liquid-cooled gasoline engine and the model of the five-cylinder star engine, but most of the research at that time was based on the gasoline engine, although the research time was not long, but the results were quite outstanding, as early as last year, the power company relied on their original research, successfully manufactured the V6 engine leading other countries.

However, as a teaching assistant, Zhang Mingwei did not continue the research of gasoline engines. Diesel published a paper this year attracted him, in the paper proposed the principle of constant pressure heating cycle, and the principle of diesel engine proposed by the marshal was completely consistent, the other party's "preemptive patent" made Zhang Mingwei quite annoyed, and it is precisely because of this that he will devote himself to the development of diesel engines, in order to seize the Rudolph. Diesel had previously manufactured engines with "constant pressure heating cycles".

But compared to Rudolph. Diesel only has the theory of "constant pressure heating cycle", in the mechanical laboratory of the unified supervision office, Dashuai once drew a simple sketch of the diesel engine, although the sketch is not very mature, but through the study of the gasoline engine, Zhang Mingwei still quickly grasped its principle, after completing the drawing design, he immediately used the equipment of the test plant to manufacture the diesel engine.

"Tom, tom......"

In the roar of the single-cylinder diesel engine, choking black smoke filled the workshop, but Zhang Mingwei's face did not have a smile, and even his brows were furrowed from time to time.

"The power of a single-cylinder diesel engine is too small......"

While sighing lightly in his heart, Zhang Mingwei once again picked up the drawings drawn in the past period of time, which was the drawings of a four-cylinder diesel engine.

“…… Do you think diesel engines can really replace steam engines? ”

The whispers of the students made Zhang Mingwei smile slightly. In Diesel's thesis, he firmly believed that the engine with "constant pressure heating cycle" could replace the steam engine, and he was only theoretical, and the test in the past half month has proved that the diesel engine has a large compression ratio, high thermal efficiency, high output power, and better economic performance and emission performance than the gasoline engine...... But will he really be able to replace the steam engine?

"Whether it can replace the steam engine, I don't know, but ......"

After a slight pause, Zhang Mingwei looked at the students around him and said.

"But generally speaking, the more cylinders of a diesel engine, the larger the bore, the longer the piston stroke, and the greater the cylinder pressure, the greater the output power. If we can make a few thousand horsepower diesel, maybe, we can really replace some steam engines, after all, the development of steam engines has almost come to an end! ”

Although he is a mechanical engineer, because he is engaged in the research of power equipment, Zhang Mingwei knows very well that the development of the three-expansion steam engine seems to be stuck in a certain bottleneck, so that there has been no substantial progress for several years.

"It is very difficult to make the power of a steam engine 10,000 horsepower, of course, the more important thing is that its size is too large to be used on the ship, so it has no meaning, but the diesel engine is different, by adjusting the cylinder, cylinder bore, piston stroke, cylinder pressure, its output power can become very large, I believe that if everything goes well, the diesel engine can easily achieve the goal of 10,000 horsepower per unit, and because it uses diesel, the oil can be loaded directly on the ship through the pipeline, and it is not as difficult as transporting coal, so it can be said that it has a lot of potential......"

In his opinion, even if it seems to be a mature gasoline engine, it is difficult to affect the threat to the diesel engine, because compared with the gasoline engine, the power of the diesel engine can be greater, and the only thing that can threaten the diesel engine is probably only the steam turbine.

Thinking of the steam turbine developed by the Beiyang Shipbuilding Power Factory, Zhang Mingwei's brows raised slightly, it seems that it is now more used in power plants, after all, compared with the three-expansion steam engine, it is more suitable for power generation than for ships because of its high speed.

"Teacher, I heard that there seem to be people in the arsenal who make vehicles that use gasoline engines, do you think we can put diesel engines on the cars as well? Like Benz in Germany......"

The students were no strangers to the invention of the automobile by Benz and others, and the light gasoline engine was installed on the vehicle as a substitute for the traction horse, although those vehicles were horse-drawn carriages with engines, but these students did not see the changes that the automobile brought to transportation, in this case, they naturally wanted to be able to install the engine they had helped to build on the horse-drawn carriage. Similar experiments are now underway at the Arsenal, but instead of putting the engine on a horse-drawn carriage, a body designed specifically that might even replace a horse-drawn carriage. Of course, the only premise is that in the case of its cheap enough.

"Diesel? Vehicle ......"

After pondering for a moment, the students' suggestions made Zhang Mingwei's eyes light up, why did he keep staring at the boat? Although the power of a single-cylinder diesel engine is not large, it is naturally not good to use it on a ship, but if it is installed in a horse-drawn carriage...... (To be continued.) )
