"Director Kong, I'm back." Zheng Ren followed director Kong with a smile and whispered.

"Is the operation going well?" Director Kong asked.

"OK." Zheng Ren said: "later, I met a patient with penetrating injury to his lower body after the lifting rod of an electroplating chair exploded."

"Oh?" Director Kong said slightly, "is the operation complicated?"

"The operation was OK. It was done slowly after pelvic artery embolization. Even the rescue consciousness on that side was a little poor, and the equipment was not good enough." Zheng Ren tells the truth.

"Do you know what I saw when I went to Haicheng?" Director Kong asked with a smile.

"Look at my technical level." Zheng Ren answered honestly.

"It's hard to work in grass-roots hospitals. You can't see the sky at a glance. Basically, all the hospitals that can go out are higher-level hospitals that go after graduation from postgraduate entrance examination and doctoral degree. You are a special case." Director Kong opened his office, sat on a chair and looked at Zheng Ren.

His eyes made Zheng Ren feel guilty.

"I remember when I went, you had an operation overnight. Your technical level was excellent and your idea of treating patients and saving people was pure, so I came back to the dean."

"Hey, hey." Zheng Ren was embarrassed to hear director Kong praise himself.

But director Kong is also telling the truth.

The level of doctors in grass-roots hospitals and people around them is almost the same. Even if a genius is reduced to that kind of place, he can't change the surrounding environment in the end. He can only enter the superior hospital by means of reading and so on.

I met director Kong bole.

"What happened to the hemodynamics you told Dr. Olson yesterday?" Director Kong asked curiously.

"Oh, it's the problem of blood turbulence." Zheng Ren simply explained: "for the problem of turbulence, the physical model is mainly simulated by Reynolds time average equation. There are also two simulation methods, one is large eddy simulation and direct simulation."

Director Kong regretted asking this question. He didn't understand what Zheng Ren said.

Zheng Ren saw that director Kong's expression was strange and immediately said, "to put it bluntly, the solution of turbulence can directly reduce the resistance.

Because of the current scientific and technological level and the limitation of computer running speed, it is impossible to do direct simulation. In that case, there will be too much data to be processed. "

"Well? Not even today's supercomputers?" Director Kong was stunned.

"Yes. After the E-Class supercomputer appears, it should be OK." Zheng Rendao: "however, it is estimated that it will take at least 30 to 50 years, which is still an ideal state. Dr. mehar and Dr. Olsen are making similar attempts to eliminate most invalid and useless data through some technical means and use the existing technology for direct simulation."

"Yes." Director Kong nodded. This time, he understood what Zheng Ren said, "are you sure about the research?"

"I'm ok. After all, the scope of intravascular guide wire is limited. Although the amount of data is also huge, the amount of calculation has decreased by 85-90% for the previous research model. The existing computers... Should be no problem."

"What about the calculation formula?" Director Kong asked cautiously.

"I haven't talked about it yet. The final formula may be named by three parties. For example, Zheng mehar Olsen turbulence formula, or something else." Zheng Ren smiled and thought that formulas such as ZMO would not be widely used in the future. He thought it was particularly absurd.

I just want to be a doctor. I have no interest in physics.

"If you do this project alone, is there any possibility of success?" Director Kong suddenly asked from a different angle.

Zheng renleng for a moment and immediately understood what director Kong meant.

It seems that director Kong did not represent himself in the conversation this morning.

"Director Kong." Zheng Ren stood up formally, put his hands on his legs and said in a deep voice, "there is no possibility."

"Sit down and say." Seeing Zheng Ren's very formal appearance, director Kong knew that he had guessed. He also changed his expression and said, "I guess you can't do it. If so, you need all the progress data of the formula."

"Good!" Zheng Rendao.

"Comrade Zheng Ren, this is no joke." Director Kong narrowed his eyes and said.

"Director Kong, I know. I promise to complete the task!" Zheng Rendao.

"I have equipped you with an assistant. You don't need to do anything. Just add the assistance you want in the agreement." Director Kong said.

"Physics expert?"

"Yes, there may be other identities."

"OK." Zheng Ren promised very simply and simply.

There is no room for bargaining about such things.

Both emotion and reason should be done. Zheng Ren doesn't want to contact specific things. God is mysterious. He has no gossip attribute at all.

If a patient is misdiagnosed, Zheng Ren is still interested.

"All right, get busy." Director Kong finished a big event, smiled and said, "the assistant is at the door. Before you go to see Dr. Mehal and Dr. Olsen, talk to him first."

"Director Kong, who is it?" Seeing that director Kong's face was not so serious, Zheng Ren asked with a smile.

"I don't know the specific information. It's not within my jurisdiction." Director Kong said softly.

"Then I'll go out." Zheng Ren stands at attention, salutes, and turns away.

Opening the door, Zheng Renjian saw a middle-aged man standing lazily at the door.

Zheng Ren looks at people. His face is full of mosaics. He can't remember his face at all. Even if not, he couldn't find any features that people could remember at a glance.

This is the kind of person you can't find when you throw it into the crowd.

"Hello, Dr. Zheng." When the man saw Zheng Ren coming out, he said hello, but his body didn't move. He still leaned against the wall. Lazily, Zheng Ren felt that he was going to sleep on the wall.

Or a humanoid plant growing on a wall.

"Boss, that side... I'll go. How can it be you!" Su Yungang wanted to talk to Zheng Ren. He was stunned when he saw a middle-aged man.

"Do you know me?" The middle-aged man was stunned and asked in surprise.

"Did you come to Chengdu a while ago? When the earthquake happened, you were rescued in the provincial hospital." Su Yun asked.

"...." the middle-aged man was silent and then asked, "are you two the people that old director Chen said?"

"Who is he?" Zheng Ren asked suspiciously.

Su Yun knew him at a glance, but he couldn't see that he had dealt with him before. Is it a volunteer from Pengxi Township? Maybe.

"Provincial hospital, Professor Huang Dazhi, the guy with thiocyanate poisoning after pumping sodium nitroprusside after aortic dissection aneurysm stenting." Su Yun said, "it's the code farmer who said code when he was unconscious. What are you doing here?"

"..." the middle-aged man was silent.

In this way, Zheng Ren was impressed. It turned out that he was the guy who came back from the death line twice.
