"Then tell me about Senior Ye's watch, do you recognize it?"
The student at the front table stared at the projection TV for a long time, scratched his head and smiled: "I can't see what brand it is, anyway, it's not Longines."
This general appearance can be placed in the mechanical department with more wolves and less meat, and still enjoy the treatment of the class flower level.
The girl asked another student behind her. This student's family background was also good. He usually liked to show off some small brands in the class, but this person looked at it for a long time and didn't see any clues.
Now students are much more active in class than those born in the 1980s. Someone started the conversation, and more students immediately participated in the topic of watches.
They want to know what kind of watch the senior brought.
Exploration — was originally a very interesting thing.
People can get great psychological satisfaction at the moment of exploring the answer. What's more, this exploration is about the legendary senior Ye Qing. The exploration of what kind of watch he brought is not too much in line with their appetite!
"I'll search online!"
"I have a cousin who runs a watch store. I'll take a picture and send it to him."
The cousin who runs the watch store is very powerful. Less than half a minute after the picture was sent, there was a rapid beeping message prompt in the chat box.
"What the hell!"
"If I'm not blind, this should be Patek Philippe, the most collectible 2499 watch."
"You can search this watch on the Internet. By the way, this one is red gold. Don't confuse it with the gold.
An indescribable sense of great satisfaction came to this student. This feeling may only be comparable to winning five kills in the LOL promotion game.
He announced the answer loudly, and then the whole class was searching on the Internet with their mobile phones.
Even Professor Cai Chenning quietly turned his back and used his mobile phone to enter the keywords of 2499 red gold limited edition.
In the following time, there were all kinds of incredulous voices in the classroom.
Some people sucked in the cold air, scratched their heads and asked why this watch was so expensive. Some people smashed their legs and pursed their lips, saying that some senior's thigh was short of a pendant, and they wanted to give birth to monkeys for senior.
"A watch that's worth thirty to forty million. If you accidentally knock it, won't you lose a house?"
"Only Senior Brother was willing to bring it out. According to the Internet, the other nine watches like this have been carefully collected and left for the next generation."
The conversation quickly came to an end because their Senior Ye Qing had already changed his posture and said something that they could not understand even if they cracked their heads.
"We are scheduled to move this civil air defense project on October 1st."
The students in the class were stunned.
"Oh my God, professor, can that civil air defense project really move?"
"250,000 tons. I remember that when large objects move as a whole, the heaviest ones are only tens of thousands of tons, and that's when they move on flat ground. The civil air defense project is underground, how can it be moved? "
"I don't think it's moving left and right because there are buildings on both sides. There's not enough space. Could it be moving up and down?"
"Moving it up and down is even more impossible. Due to the influence of gravity, we must exert a greater force than moving it left and right to move it."
The students couldn't guess, so they asked the professor if he knew how to move the civil air defense project.
How to move it involved the technology of the mechanical industry. This is exactly the profession of Professor Cai Chenning. But he hesitated for a long time, his brows wrinkled into a group, and after a long while, he said: "This problem is an assignment. Everyone starts to use their brains and sets out a reasonable plan."
"You hand in your homework before October 1st, and then we will choose who has the closest design plan based on the picture of the construction site."
The class was suddenly silent, and the students looked at Professor Cai Chenning in amazement. It was even more incredible than seeing the civil air defense project move.
"Cough ~ Watch TV, watch TV." Professor Cai Chenning turned his head to hide his embarrassment.
This awkwardness didn't last for too long. On the TV, that beautiful and charming host who charmed all the boys asked Ye Qing a question that most of the students were very interested in.
She asked Ye Qing, what words do you have to say to the young people in front of the TV?
"Plan an extraordinary life goal for yourself."
"Our company has an engineer..."
"Now, he casually pinches a ball of alloy wire and earns 30 million in half an hour."
A super inspirational story of someone who was born in the mountains and didn't even have enough to eat.
Although the first half of this story is not the same as the life experience of the Master Craftsman, the second half is not exaggerated at all.
In the mechanical engineering class, the boys' eyes were red.
Not moved, but stimulated by the 30 million yuan!
"Professor … Professor, is it really possible to make machines? Can someone really make 30 million in half an hour?" A boy in the front seat asked: "When I started school, there was a senior who told me that the mechanical students were all single dogs, and it would be hard to find a wife in the future?"
Professor Cai Chenning was drinking tea. He sprayed out a mouthful of water and coughed again and again.
"Cough ~ Who, which department said it?" Professor Cai Chenning slammed his chest, his face turned red, and said vaguely, "Didn't your seniors tell you the answer?"
"I haven't seen 30 million yuan in half an hour, but in 1985, when the Zhongyun First Machinery Factory was not closed down. There is one thing that I still remember. "
"At that time, the Zhongyun Thermal Power Plant built a new generator, the First Machinery Factory, responsible for producing a 500-megawatt power generator. The generator had to be used with the steam turbine. At that time, we had no technology to make steam turbines, so we could only import them from Germany. As a result, the generator we produced had a slight noise and tremor when it was running. "
"After the speed was raised to 1500 rpm, the generator with a diameter of 3 meters, the noise and tremor could be felt by laymen with their hands."
"The rated power of the motor is 1800 rpm. If the speed is not reached, the electricity emitted naturally cannot be used in the grid. The most fatal is that under abnormal tremor, the steam turbine that provides power to the engine through the transmission shaft connection will also be damaged. "
"A steam turbine unit costs nine million US dollars. At that time, the country's foreign exchange was earned little by little by handicrafts. If the steam turbine unit was damaged, it would be the rhythm of being scolded to death by the people of the country."
The students in the class did not speak and listened attentively to the professor's memories.
Professor Cai Chenning continued to drink tea and said: "All the experts of the First Machinery Factory came, and my mentor and I were also invited to participate in the troubleshooting."
"As a result, all of us worked overtime for three days. More than 20 tons of stator coils were rewound and the rotor was reinstalled. In the end, the main shaft was removed and measured inch by inch with an instrument. The old master touched it back and forth with his hands until his hands were blistered. "
"As a result, when we thought there was no problem and the motor was reinstalled, the abnormal noise continued to exist."
"The power supply shortage in Zhongyun lasted for a week until Siemens sent a technician over to maintain the steam turbine. Only then did we meet our savior and consult their technician."
"The German technician only checked for an hour and told us that the cause of the failure had been found. But he asked for 100,000 US dollars to tell us where the problem was. "
"100,000 US dollars in 1985, according to my salary of 60 US dollars a month at that time, I would have to not eat or drink for 200 years to earn that much."
"Here, this money has to be given."
Professor Cai Chenning's face was full of regret: "The German technician said that on both sides of the motor cover, the concentricity of the shaft holes of the main shaft has a slight deviation."
"Two cover plates with two holes. Because the holes were not made properly, we lost 100,000 US dollars of foreign exchange."
"100,000 US dollars in the past, according to the purchasing power, is equivalent to our savings of 10 million US dollars now."
After saying this, Professor Cai Chenning changed to a serious tone.
"Students, do you think that if you study mechanical engineering well, you can make a lot of money and reach the peak of life?"
"Yes!"
