Qin Hai is in peace, some are somewhat deficiency, he said: "I don't mean this, I said, if you really have a look, you will tell me.

"What?"

It's quiet to react, asked strangely.

Qin Haidao: "I cut the death.

"You swear, you swear!"

Quiet turn is a happy, and it is embarrassed to directly show the feelings of the happy, only to catch the fault of the Qin Hai storm, and put the top of the powder.

Qin Hai hip smiled, dodge, and a spring in the house.

"Hey ... I still go to the school library to read the book.

Qin Shan can't see it. Although one is his own brother, one is his own girlfriend, but this kind of child is not suitable, how can she look at it calmly calmly.

She stood up and intended to clean up their own bags.

"Okay, don't make trouble.

Xiaoshan, let's let Qin Hai we go to watch the movie? I haven't seen movies for a long time.

Quietly released Qin Hai and said in the arm of Qin Shan.

"I can……"

Qin Shan just wanted to refuse, suddenly the bead turned, smiled: "Okay, brother, you invite me quiet to watch the movie."

"This is easy, let's go, let's go to eat, go to the movie.

Qin Hai refreshed quickly.

Three people have eaten a simple late (meal.

From the restaurant, I was preparing to drive the five movie theashers who went to don't worry. Qin Shan suddenly thought of what I thought of, I took my head: "I have to die, I want to die, I think of this evening, my sister is about me. In the experiment, I forgot to clean it ... Brother, Xiao Jing.

You two go to the movie, I will go back to school.

If you say, you don't wait for the two, and she ran away.

Qinhai looked at the back of his sister, muttering a way: "Such a big person, it is still like hairy grass.

Really ... "

When he said, he suddenly found that the eyes of peace and rising, he looked at himself. He looked at it. He understood that Qin Shan was what kind of grass, clearly did not want to make a light bulb, I found a retrieval.

After I understand this, he smiled in the quiet: "You see, Qin Shan is gone.

Otherwise, let's go to the movie ... "

"Are you not happy?"

It's quiet to laugh and laugh at Qinhai.

"Nothing, I am very happy.

Qin Hai said, "I just thought, I should also care about Qin Shan's life problem, and quickly give her a boyfriend.

"Ha, you only think about it now, your brother is too unhappy.

Now I think I have to care about my own sister.

Say quiet.

Qin Hai is a loyal look, saying: "Not this.

I said, hurry to marry her, saving her eyes ... "

"Qinhai, you are really yin!"

"If you don't, I want to make it out of the door, where to go to the door ..."

"Who is with you ''.

Qinhai, you are too narcissistic!

"..."

That night, Qin Hai lived in the housing of quiet and Qin Shan, of course, he lived in Qin Shan's room.

Qin Shan went to a room to sleep with a room.

The Chinese society in the early 1990s is not open enough, and Qinhai does not dare to get dangerous by Ning Zhongying, and do something that is injured.

Early the next morning, Qinhai opened the car to send the quiet to the Beijing University, and then with Qin Shan, go straight to the chemical design.

He and the Fan Zhiyuan of the Chemical Design Institute, today I want to discuss the design of the ethylene set of equipment.

Ethylene is a basic chemical product, and many polymer materials require ethylene as raw materials.

Qin Hai is a breakthrough in ethylene, and is involved in the field of basic chemical workers. It is a policy that has already been determined.

As early as a year, he entered the design work of 800,000 tons of ethylene equipment in accordance with the establishment of Hua Qing University Chemical Engineering and National Chemical Design Institute, so far.

Before accepting the entrustment of Qin Hai, the Chemical Design Institute has been designed with 300,000 tons of ethylene equipment, and has certain experience, so the progress of the principle design is very smooth.

However, when the problem involving the equipment manufacturing process, the chemical design institute has some grasp, the most important block tiger, is a low temperature material that needs to be used in ethylene equipment.

Ethylene production involves many low-temperature links, so-called "ethylene three machines" used in the production process

It is also the ethylene compressor, propylene compressor and cleavage gas compressor working under low temperature conditions, where the inlet temperature of the propylene compressor is generally 40 degrees Celsius, and the inlet temperature of the ethylene compressor reaches 102 degrees Celsius.

Under low temperature conditions, the strength of many materials will be greatly reduced, so that the normal use of the equipment cannot be guaranteed.

Therefore, to make a vinyl device, the low temperature material is the most critical part.

In a compressor, there are many different components such as rotor impeller, spacer, bushing, screws, nuts, welding enclosures, casting enclosures, etc., each component is also different because of the different working conditions.

China has long unable to achieve 100% domesticization of the ethylene three machines, mainly due to certain grades of low-temperature steels cannot be produced independently.

In this case, Qin Hai resolutely invests 20 million yuan to help the chemical equipment institute have established a low-temperature material research center, and they can go to Ä Roth, hired Victor-Columns, etc.

Recently, Fan Zhiyuan, director of the Low Temperature Material Research Center, to call him, inform that the research of low temperature materials has made significant progress, and he is today is a special trip to understand the specific situation.

As for the sister Qin Shan, Qinhai has decided to arrange her as a supervisor arranged in the Low Temperature Material Research Center.

In the future, Qin Hai also has to establish a Daqin Chemical Engineering Technology Research Company in this low temperature material research center and several other chemical laboratories, and Qin Shan will be appointed as the chairman of this company.

During this time in Qinhai, Qin Shan will walk away from these laborators by Sancha 5, understand the specific research situation, and report to Qinhai by telephone.

Although Qinhai did not clearly tell Fan Zhiyuan and others about Qin Shan's arrangement, everyone knows that Qin Shan is the sister of Qin Hai, and can also guess that Qinhai arranges her in the laboratory, so I will not refuse her. Patrol.

"Welcome, welcome Qin Chairman to the Chemical Design Institute to inspect.

At the door of the design, Fan Zhiyuan took a few research rooms waiting for Qin Hai, seeing Qin Hai's car stopped, everyone went around, and he said enthusiastically.

Qin Hai and Qin Shan have taken a car, and Qin Hai is holding hands with everyone. Qin Shan has a few distinct expressions, followed by Fan Zhiyuan after the Qinhai's body.

After greeting each other, Fan Zhiyuan asked: "Chairman Qin, is we directly studying the center, or first go to our research room to sit?"

Fan Zhun's official identity is the director of the first research office of the Chemical Design Institute. Please ask Qin Hai to the study room, belonging to a relatively official reception etiquette, and directly to the research center is more casual.

The Qinhai is not a person who cares about the name. He put his hand: "Director Fan, we will not be polite, go directly to the research center.

"okay then.

Fan Zhiyuan should have, he explained a subordinate to the research office to inform everyone to the study center to meet, he got the Qinhai car, with Qinhai to the newly completed research center downstairs.

As for those who went to the door to meet the Qinhai, they rushed to the bicycle.

Qinhai has just entered the building of the research center under the leadership of Fan Zhiyuan, and he hit an acquaintance, which was the colored Jie, who was digging from the Soviet Union.

The column of Jieli is a special trip to meet the Qinhai, see Qinhai, and his smile opens his arms.

Qin Hai is not amboupted in this Russian etiquette, haha ​​smiles with the other party, then asked in English: "Mr. Jie, is you still used to China?"

"Thank you Mr. Qin, I am very used to China and my wife.

Collection of Jieli said, "Especially my wife, in addition to the summer weather is too hot, she feels that everything in China is very pleasant.

"Mr. Ramov Moff is good?"

Qin Hai greets the finish of Jie and Die in the Soviet Union.

Cai Jie Road: "His body is also very good, he is still going to go back to China for a while.

"We are very welcome.

Qin Hai said, he turned his way to Fan Zhiyuan, "Director Fan," Mr. Fan, Mr. Ramov to China, all reception costs are borne by the research center, and it is necessary to give old gentlemen to provide the best treatment.

"Haha, Qin always rest assured, we will take care of Mr. Ragamov.

Fan Zhiyuan said.

Qin Hai did not ask the Jiejie asking his son Xie Liaosha, because Xie Liaisha is now following the good things, in fact, a peripheral staff of Daqin Group, Qinhai's current situation is very understandable.

According to thank you, Xie Liaisha is now famous in the Chi Tata and the surrounding states. Everyone knows that he is a Chinese company's gorge, many of the technicians who think of China to go to Taobao is in contact with him.

I talked about a few new words, Qin Hai said: "Mr. Jie, Mr. Jie, I will come here today, mainly to understand the research of low-temperature steel, listen to Fan Director, this time study is mainly you are led. Is it possible to ask me to do a more detailed introduction? "

Cai Jie Tao: "Director Fan has already explained me yesterday, I am very happy to introduce you to our latest research progress, you please come with me.
