I personally created the dragon chant of the great nation

Chapter 44

At this time, it was too early to start writing the thesis.

Qin Jinsong felt that even if Comrade Chen Qingxuan was a genius, he would not be able to write a thesis within a few days of enrollment.

But it's rare to have this heart.

"Your classmates, you haven't memorized the most basic concepts."

Qin Jinsong was in a good mood and said with a smile.

"Okay, I'll take a look at your proposal first. If we can, let's start and try to write a paper. "

"Don't get your hopes up too much, though."

"We Qinghua have always been very strict with our thesis requirements. I have some connections in the school newspaper, so if not, I can help you publish an issue in the school newspaper. "

That's the consolation prize.

It's like an elementary school student who publishes an essay in his school's school newspaper.

The difference is that this is Qinghua.

It is also very good to be able to publish a paper in Qinghua's school newspaper.

Chen Qingxuan listened to Professor Qin's comfort, but he just smiled and said noncommittally: "Then you can take a look first." "

"Hmm."

Professor Qin put on his glasses and looked intently.

"On the Application of Mechanics in Involute Gear Processing Technology."

Qin Jinsong slowly read out the question, and his eyes lit up.

"You're a good choice."

"Not only our big country, but also the gear process is the object of research in the world."

"It seems that your understanding of engineering mechanics is indeed quite profound."

Professor Qin nodded appreciatively, then shook his head again.

"But, alas."

"Your topic is too high."

"It's a problem that the whole world is studying."

"How can it be studied so easily?"

"I suggest you choose one that is a little more down-to-earth, so that it is easier to study and easier to publish..."

Seeing this, Qin Jinsong shook his head slightly and said enthusiastically.

Just speaking of which.

His voice stopped suddenly.

The pupils dilated in disbelief.

The hand holding the opening report gradually trembled.

"Involute gears can be designed for a variety of displacement and modification to facilitate precision machining and interchange."

"However, the contact strength of the soft tooth surface of the involute gear is weak, and the general quality level is not high, so when it encounters a heavy load, it often fails and has a low service life."

"Therefore, it is possible to develop a single arc gear, which mainly relies on axial transmission of motion, and when perpendicular to the tooth surface, it can instantly contact the tooth direction, and the contact strength is significantly improved..."

Qin Jinsong's voice trembled, and he read it excitedly.

Below is a relatively simple model painted by Chen Qingxuan.

Because there is no formal paper, the data given is also vague.

"Spur, helical, bevel gears..."

Names that had never been heard of were constantly read out in Qin Jinsong's mouth.

"Yes, yes!"

"Comrade Chen Qingxuan, I retract my opinion on your paper just now."

"Your paper is very deep."

"And theoretically, it's highly feasible!"

"In the engineering of a big country, gears are used everywhere and are widely used."

"If your paper can be established, it will bring great changes to gear machinery!"

Qin Jinsong said, stood up excitedly, and grabbed Chen Qingxuan's hand.
