Chapter 0004 - Aerodynamics (Ask for Recommendation)

"There are flaws. ”

Zhou Jingming just said the true thoughts in his heart, but he didn't mean anything else, and he didn't think much about it after he finished speaking, and continued to look down, making notes on the paper while reading.

However, as soon as he finished speaking, there was a dead silence in the entire office, and then there was a burst of laughter.

Zhou Jingming was shocked in his heart, and then he realized that he was in the college office, and the person who was talking to him just now, he didn't even know who it was!

The college entrance examination system has just been restored for a few years, and respecting teachers and valuing education is particularly important in that era.

"I'm sorry, teacher, I was just idle and bored, so I read your high work by the way, and I didn't mean to be offended. ”

In a hurry, Zhou Jingming hurriedly stood up and bowed and said. Privately looking at other people's academic achievements without their permission is indeed something Zhou Jingming did wrong.

At this time, Zhou Jingming saw clearly who the person he was talking to just now, dressed in a Mao suit, with gray hair, and a pair of reading glasses, giving people a feeling of being an old pedant.

"This man is so familiar, as if he had seen it somewhere. Zhou Jingming only glanced at it a few times, and then quickly lowered his gaze.

"Little classmate, do you know who this teacher is?

"Although newborn calves are not afraid of tigers, the sentence just now is a bit arrogant! ”

"Hahahaha Professor Su, it seems that your paper can't be published for the time being, even this little student can see that there are flaws, let alone the magazine, and it will definitely not pass the review. ”

…………

There was a lot of laughter in the office, but most of it was good-natured ridicule, but no one actually went online.

Professor Su ...... Could it be Professor Su Wangting?!" Zhou Jingming was even more shocked in his heart, this Su Wangting was the chief expert in the Agricultural Machinery College, and he was an absolute authority in academics.

Although from his own point of view, Su Wangting's paper does have a lot of problems, but judging from the academic level of this era, Su Wangting's thesis research is already very advanced, and he said that his research was "flawed" in front of so many people, I don't know if this Professor Su will be angry with himself.

"Little classmate, you just said that my paper is flawed, can you tell me, which is the flaw?" Su Wangting said with a smile.

Su Wangting, who was born in a scholarly family, would not be angry with Zhou Jingming because of this, on the contrary, for this young man who dared to think and speak, Su Wangting even felt very appreciative, the academic community needs to be such a young man, not a thousand horses.

Zhou Jingming's eyelids rose, not knowing what to say or what kind of degree to say.

"Professor Su, you are embarrassing this little classmate!"

"That's right, in the entire Runzhou Institute of Technology, who can compare to you in terms of academics. ”

The surrounding teachers continued to tease.

"I see you just made a note, can you borrow it for me to see?" Su Wangting smiled and pointed to the paper on the table.

"Absolutely. Zhou Jingming hurriedly took the notes and sent them to Su Wangting with both hands.

There is not much content on the paper, it is very concise, and ordinary people must not understand what is written, but Su Wangting just swept it, and his heart immediately understood, and he couldn't help but look up and look at Zhou Jingming deeply.

How did this kid know that he was able to sort out all the key points of this paper, and that there were a few formulas that I didn't even list?

"How many times have you read the article?" Su Wangting raised his head and asked quietly.

"I only watched it once...... No. Zhou Jingming couldn't figure out Su Wangting's attitude, so he could only answer truthfully.

Su Wangting's eyes lit up, and in less than one effort, he was able to list all the major and difficult points of this paper, and analyzed them all, is my thesis level not enough, or is the level of this young man in front of me too high?

It's just that the word is written...... It's a bit ugly. It's all said that the words are like their people, the young man is very handsome, and he is almost catching up with the old man When I was young, how can I write it like a crab crawling?

"What are the flaws you just mentioned?"

Zhou Jingming secretly complained in his heart, why is this still a bar?

The rest of the teachers were snickering on the side, Su Wangting's old pedant temperament is well-known in Runzhou Institute of Technology, if Zhou Jingming doesn't say one, two, three or four today, don't think about going out.

"It's okay, just tell your true thoughts, whether it's good or bad, I won't blame you. Seeing that Zhou Jingming was very restrained, Su Wangting smiled and said with relief.

Zhou Jingming raised his head and glanced at Su Wangting, the old professor's eyes were full of encouragement, and the smile on his face also showed that the old professor was very kind.

Zhou Jingming took a deep breath, "Since Professor Su said so, then the student is ugly, if there is anything wrong with what he said, please don't laugh at Professor Su." ”

Anyway, what I said is all right, it depends on whether Professor Su can understand it, after all, there are many theoretical achievements, which are very advanced, and Western countries may have studied them, but they have not yet been transmitted to China.

The other teachers also put down what they were doing and pricked up their ears, wanting to hear what Zhou Jingming could say.

"We all know that there are three evaluation indicators for the dynamics of the car, the maximum speed, the acceleration time and the maximum climbing, and the factors that determine the upper limit of these three indicators are nothing more than two, driving force and driving resistance. ”

Su Wangting nodded while listening, what Zhou Jingming said, but any student who has studied automobile theory knows that it is not a clever place.

Zhou Jingming paused, and then continued.

"Driving resistance, mainly divided into four parts, rolling resistance, slope resistance, acceleration resistance and air resistance, these four resistance factors, determine the size of the resistance in the process of driving, and then affect the dynamics of the car, Professor Su's paper, focus on the analysis of the first three resistance on the power of the car, and give a way to reduce these three resistance, these problems are not big. ”

Zhou Jingming licked his lips, "The biggest problem with this paper is that Professor Su completely ignores the influence of air resistance, which should not be and is not right! Moreover, simply improving the power of the car from the perspective of the other three types of resistance actually has little effect." ”

Su Wangting was even more shocked in his heart, this kid actually saw the weakness of this paper all of a sudden?

"Then can you specifically analyze the impact of air resistance and its improvement?" Su Wangting continued to ask, he wanted to see how far Zhou Jingming could speak.

"Absolutely. ”

Zhou Jingming replied without hesitation, "But before that, I want to ask Professor Su, do you know about automobile aerodynamics?"
