……

Zhuo Ling said with concern: "Senior brother, are you okay? Coach Fan is also a little too much, you have just started learning, why do you let you feed the moves, what if you get hurt?"

She has always been the youngest in the class since she was a child, so that she met Liu Chen, the only junior, although she was older than her, the senior sister screamed, her heart was still overflowing with love, and she subconsciously wanted to take care of him, which Liu Chen did not expect, if she behaved more mature and indifferent, I am afraid that there would be no such benefits.

Liu Chen smiled: "It's really okay, it's just that I'm too stupid, and I don't understand what Coach Fan said, so I have to demonstrate." ”

"You can't do that next time, this kind of sports is more about spending time practicing, forming an instinct, you have just practiced, and it's normal to not understand. Zhuo Ling was still indignant, it seemed that she was going to go to Fan Peng to talk about it, Liu Chen's heart was warm, and he couldn't help the heat in his heart, and looked at her with an expression.

Zhuo Ling was still pouting, a little angry, turned her face, and saw the junior in a daze.

Ma Rui saw it from the rearview mirror, and he couldn't wait to tear his mouth, why do you have to mention this!

"Junior, what's wrong with you?"

"We met in Pingshui, and my senior sister was so good to me. ”

The gaze was very scorching, Zhuo Ling tilted her head and smiled, suddenly touched Liu Chen's head, and said, "Fool, you just graduated from high school and came out of your hometown, and you still ran so far all of a sudden, and you are not familiar with life, of course I have to take care of you." ”

Liu Chen's eyes were a little red, yes, in his previous life, he was dedicated to technology. In fact, her mind is not mature enough, and many times it is Zhuo Ling who takes care of his life, and even gives up her own hobbies and life ideals.

In front of his lover, no one keeps a straight face. It's normal to treat each other like children.

Looking at his appearance, Zhuo Ling thought he was homesick, patted him on the shoulder, and comforted him like a big sister: "It's okay, senior sister knows a lot of people in Suzhou City." Tell me if you have any problems. ”

Well, Liu Chen nodded.

Ma Rui couldn't wait to slap himself, his brain was squeezed by the door before he said that, he looked at Liu Chen more and more unpleasantly, he only felt that the threat was too great, but Zhuo Ling liked to take care of him very much.

Glancing at Liu Chen, Ma Rui's eyes rolled and said with a smile: "Ling Ling, I have something to discuss with you to see if you are interested." ”

Zhuo Ling raised her eyes and said, "What?"

"Nowadays, cars are becoming more and more electric. The BMW 7 engine does not need valves, and the unique Valvetronic electronic valve technology is adopted, the engine load change and cycle management are better than the traditional one, the engine runs more smoothly, and the car does not feel bumps. ”

Ma Rui smiled and talked eloquently, paying attention to Liu Chen's expression, heh, this kind of poor student who came out of a small ravine probably doesn't know what kind of car this is. It's time for you to popularize science.

"Well, it does feel stable, but I didn't expect that there is such a reason, and the electronic car is a major trend. Zhuo Ling nodded. "Do you want to study automotive electronics too?

"Ling Ling is smart. Ma Rui smiled, "You look at the current car steering wheel, from the beginning of the pure mechanical structure, very difficult, to the development of hydraulic power steering, through electro-hydraulic power steering." At present, the mainstream luxury cars are all electric power steering, and I am ready to apply to the school for a project to study in my junior year, aren't you also ready to enter the laboratory, join in, and strive to publish a few high-quality papers, which are needed to apply for schools abroad. ”

Zhuo Ling said happily: "That's good, just listening to it makes me think it's very interesting, the last time I drove my father's car, I still felt that the steering wheel was a little heavy." ”

"By the way, Senior Brother Liu Chen, why don't you join in, you are familiar with MATLAB, and you will definitely need a lot of simulation work. ”

Ma Rui deliberately said this in front of Liu Chen, who knew that Zhuo Ling invited Liu Chen, without waiting for Liu Chen to speak, he immediately said: "Ling Ling, I'm afraid it's not appropriate to invite Liu Chen's junior, he has just entered the school, and the coursework in his freshman year is very heavy, especially advanced mathematics, that is the foundation of the university, or focus more on learning, scientific research work is time-consuming and laborious, not as simple as you think, in case you delay your study, it will be troublesome." ”

Zhuo Ling thought about it and made sense, and said apologetically: "Yes, junior brother, the freshman year is very heavy, you have to study hard, especially advanced mathematics, our Jianghai University has very high requirements, and there are very few students who can get A in the end, and the failure rate is very high." ”

Liu Chen smiled: "Senior sister must be A, right?"

"Well, I finally got an A+. Zhuo Ling is very happy, obviously she can still get good grades in front of the top students gathered from all over the country, and she is also very happy.

"Well, then I have to learn from my senior sister and try to get an A+. ”

Ma Rui said with a smile: "The spirit of the younger brother is really high, the passing rate of advanced mathematics is strictly controlled, there are very few students who get A+ in the whole school, every student who enters Jianghai University is a super student in high school, everyone is very smart, and everyone is pretentious, in this competitive environment, it is not easy to get out of the way." ”

Zhuo Ling patted her chest and said, "Don't be afraid, junior brother, when the time comes, we will study together and I will tutor you." ”

"Okay!" Liu Chen was very happy, although he didn't need counseling at all.

Ma Rui put a sentence in his mouth and almost bit his tongue.

Liu Chen said with a smile: "Automotive power steering system, I also have a little research, now the electric power steering system is very mature, the key technology is the manufacturing process and servo control of the permanent magnet synchronous motor for driving, several automotive suppliers have launched stable products, such as Delphi company, the cutting-edge topic is SBW, this school research is very interesting." ”

"The junior knows a lot, but you may be mistaken, now the more high-end cars on the market are equipped with electric power steering, many cars are hydraulic as power, do you understand? Don't pretend to understand, what is this SBW?" Ma Rui was quite unhappy.

Zhuo Ling also looked at Liu Chen curiously.

"SBW, that is, steering-by-wire, the first concept proposed by foreign countries, has been very hot in recent years, and it translates to electronic steer-by-wire, which is a research direction developed on the basis of electric power steering systems. ”

"Why haven't I seen it, it can't be that you are making it up, which model uses this thing?" Ma Rui was a little angry, Zhuo Ling frowned, a little disliked.

"It's just that it's too cutting-edge, so there is no car configuration in the world, which is a revolutionary change in automobiles, and there are still many technical problems to be solved. ”

"Don't be so mysterious, let's talk about what this SBW is? If it's really good, the BWM7 should be equipped with it. (To be continued.) )
