At this time, Sioux City was in a small restaurant on the edge of the square, worrying about a basin full of noodles.

Xiao Hei snored, dug half of his pot into it in a minute, looked up and asked in surprise, "Why don't you eat it?"

"It's too much. ”

"The specialty of this shop is that it is full of quantity and tastes good. If you don't finish eating, the boss will be upset. Xiao Hei pointed behind him with the head of his chopsticks.

Su Cheng looked at it, and sure enough, there was a chubby boss, holding the rough black boss lady, and looked at him fiercely.

"I'll give you half of it. Su Cheng couldn't help but say and poured half a pot of noodles into Xiao Hei's bowl.

Turning his head again, the chubby boss and the coarse black proprietress had disappeared into the smoke, like a cook in the gods.

"You're in Chapter 11: Gadgets!" Shu Lan cried out crisply, "Su Cheng, I'm looking for you so hard." ”

Xiao Hei looked at Shu Lan's pink face, long black hair, and big shiny eyes, and said admiringly: "Su Gong, you have a good relationship in Dong*ying, and you said that you don't want to come......"

"What nonsense are you talking about. On a crowded occasion, Shu Lan suddenly had the free and easy generosity of a girl from a working family, and after glaring at Xiao Hei, she asked Su Cheng strangely: "Why does he call you Su Gong, aren't you in the oil production team?"

"There are no engineers in the oil production team?" Xiao Hei muttered, and under Shu Lan's fierce eyes, he walked away.

Shu Lan sat down honestly and unceremoniously, and said coquettishly: "I went to the library to look for you, but you left first, and you asked all the way to find me, and I was tired to death." Boss, bring me a bowl of noodles!"

Sioux City wanted to stop it, but the chubby boss had already responded: "Okay!"

Shu Lan smiled, leaned back on the chair, stood out from the proud twin peaks, and said: "My teacher's name is Liang Jianguo, and he is from the Craft Research Institute. He looked at that sketch you drew and thought it was very good, so he asked me to come to you. Hurry up and eat, and we'll be over in a moment. ”

"It's time for him to get off work. Chapter 11: Gadgets "Sioux City didn't want to go a little, and there was naturally no problem with the expansion connection, but he didn't know whether he should take it out or not.

Shu Lan only thought he was reserved, and said with a smile: "We'll go to the teacher's house in a while, the dim sum made by the teacher's wife is delicious, and you take advantage of it." ”

As he spoke, a bowl of noodles like a small basin was brought up by the thick black proprietress .

Su Cheng looked at the noodles he hadn't finished eating and whispered, "It is said that if you don't finish eating, the boss will be unhappy." ”

"It's okay, I can finish it. Shu Lan smiled shyly and waved her chopsticks to start.

In Su Cheng's surprised gaze, a bowl of noodles bigger than the little girl's belly disappeared out of thin air.

All that was left was Shu Lan's gentle smile.

At Liang Jianguo's home, Sioux City was received cordially and friendly.

The vegetarian oil dim sum made by Mrs. Liang did taste very good, but after Su Cheng ate a small half bowl of noodles, he was no longer able to bear it, but Shu Lan ate three palm-sized dim sum as if no one was around.

Su Cheng roared in his heart: Don't think I don't know you just ate a whole pot of noodles.

After the greetings, Liang Jianguo took out the drawings with the schematic diagram and said with a smile: "Xiao Su, how do you want to do this shaft sleeve connection, tell us in detail." ”

"It's actually simple. Su Cheng hesitated slightly, but still drew a schematic diagram of the expansion of the connection.

It's a simple gadget, it's worth a lot because once it's used, it saves millions of dollars a year in oil field maintenance costs, and it's not worth a lot because it has a cost of its own. To change the structure of the existing gearbox in the oilfield, it is necessary to change the production line of the factory that produces the reducer, and replace tens of thousands of existing gearboxes in the oilfield, as well as a comparable number of spare parts. This kind of one-time investment of tens of millions of dollars is an important decision for state-owned enterprises, and it is not something that Sioux City can control.

If you want to make money from patent fees, Sioux City is afraid that you will have to wait another 20 years, and you will have to be lucky. Because at that time, God knows how many bushing structures will appear. From the perspective of the user, of course, it is necessary to choose the one that does not have royalties.

However, Liang Jianguo only thinks about technology, and while watching Su Cheng draw, he bowed his head and said: "Your drawing skills are very good, are you in our petroleum technical school?"

The large state-owned enterprises in the 80s were like independent kingdoms, which could meet all the needs of a person's life, old age, sickness and death. For example, Shengli Oilfield, a large state-owned enterprise, covers a wider scale, they not only have their own petroleum technical school, but also have a health school and a normal school, and every year from the Ministry of Petroleum exchange some petroleum university places, the education part is almost all self-sufficient, Liang Jianguo has this question, it is also habitual.

Su Cheng smiled and replied, "Self-taught." ”

Liang Jianguo looked at the drawings again and sighed: "It's old." ”

Shu Lan was beside him and said, "Master, don't you want to see his data?"

"That's embarrassing. Liang Jianguo said abruptly, but the desire in his expression was clear.

"It's fine. Su Cheng didn't say anything like patents, and the engineering courses he studied, which of them were not the classic shapes of later generations, and they were just swelling and connecting, what was it.

He wrote the graph: "The size of the connecting bolt is related to the allowable stress of the bolt......

Liang Jianguo listened very seriously, asked a few questions from time to time, and made notes in a red-covered notebook.

Such expressions have always appeared on Liang Jianguo's students.

Shu Lan suddenly looked up at Su Cheng and looked at his somewhat thin cheeks...... The latter seemed to be aware of this, and when she turned her head, she quickly dodged again.
