Chapter 431 (1/2)
After Xu Wenyuan left, Gu Zhennan asked Guo Xiang, ”what is this NMR?”
”It's an MRI, which is an image examination method. It's like the CT you did in Beijing last time. However, MRI is more powerful than CT.”
”CT is a cross-sectional imaging formed by X-ray penetrating the human body, which cannot carry out multi-directional imaging, and may cause radiation damage to the human body. Of course, the current CT examination is generally within the safe dose range. There is no need to worry about doing one or two examinations. ”
”Nuclear magnetic resonance is a resonance generated by the atomic nucleus. Zeeman splitting occurs under the action of external magnetic field. Radio frequency is generated through resonance, and the collected signal is formed into an image through amplifier and image acquisition system.”
”MRI can perform multi-level and multi-slice imaging, which is much more powerful than CT. And nuclear magnetic resonance imaging is a kind of hydrogen proton imaging, which generally will not cause harm to the human body. ” Guo Xiang said.
Because she often used it in her previous life, she had a special understanding of this instrument, and her memory ability was strong, so she remembered it more clearly.
”How do you know so much?” Gu Zhennan was surprised that he didn't know anything about splitting and RF. This is the category of physics.
”In fact, I don't understand the specific principle. I just wrote down all these after reading a book. I probably know a little.” Guo Xiang blushed. Did he say too much.
”Nuclear magnetic resonance imaging is particularly clear for the central nervous system, brain, spinal cord, skeletal system and soft tissue imaging, such as tumors or bleeding, cerebrovascular diseases, etc., which is very helpful for doctors to judge diseases.”
In terms of medicine, Guo Xiang naturally talked more freely.
”So with this instrument, doctors can diagnose the disease faster and take corresponding measures earlier. Patients can be treated in time. Maybe they won't delay to the late stage of the disease and can save people earlier.”
Gu Zhennan nodded. It turned out that the instrument was so useful. No wonder his daughter-in-law agreed to the project as soon as she heard about it.
”Isn't it easy to develop this?” Gu Zhennan asked.
”That's natural. NMR is a physical phenomenon. It's a real high technology. It's very difficult.” Guo Xiang nodded, ”but the United States already has it. I don't know how much technology they can reveal. If not, it's still very time-consuming and laborious.”
”Let's see what Xu Wenyuan said then. The agreement should be signed after you see it clearly.” Guo Xiang said.
Gu Zhennan nodded. He didn't worry about this. His daughter-in-law is much better than himself. He just needs to be responsible for giving money.
In other words, the money has always been in the hands of her daughter-in-law, and she hasn't moved it.
Of course, Gu Zhennan has half of the shares in the machinery factory. As long as the factory makes money, he doesn't have to worry about having no money.
By the way, he also has a cement plant, but it doesn't seem to be profitable yet.
At that time, the divorce agreement said that the shares of the machinery factory were given to Guo Xiang, but the original situation was maintained before the marriage.
It's just that the money from the waste oil well has always been in Guo Xiang's account, and she still has the working capital.
”School starts tomorrow. Won't you be used to the new school?” Asked Guo Xiang.
”It should be all right. I'm not a child. Just adapt more.” Gu Zhennan said.
”By the way, does your school stipulate that you must live on campus and can go home every day?” Asked Guo Xiang.
”Yes, I already applied for no residence when I transferred. And you? ” Gu Zhennan asked.
”Our graduate students can not live on campus. Some of them should have been married like me.” Guo Xiang said.
