   Wei, who may be able to buy a Hermes stethoscope, heard this and thought: This problem is not too big for me, then I will ask my dad to pay the teacher to buy more for me.

   Think simple. Wei classmate. The hassle goes beyond just the money to buy the animals. The animals you buy are not for direct use, and many experiments require animal models. Because the basic research you do in clinical medical research is disease, the animal must be used to simulate a patient with a certain disease for convenient research.

   For example, during their internship in the obstetrics and gynecology department, Xie Wanying and Duan were fortunate to have access to some clinical research project documents. When the teachers were studying gestational diabetes, they wanted to establish a rat model of gestational diabetes in the laboratory.

   Where did this model come from? Either buy it from a relevant model company, which is much more expensive than ordinary experimental mice, and there are tens of thousands of each. No matter how rich you are, it is difficult to burn such huge sums of money. Most of the time, researchers will try to model and raise sick mice on their own. First of all, the rats bought to meet the experimental requirements of weight and age were raised for two weeks, so that they were familiar with the surrounding environment and diet to avoid external factors affecting the experimental process and results. Then the male and female mice were mated, and after confirming the pregnancy, they were divided into the control group and the experimental group. The two groups of pregnant female mice were injected with normal saline and streptozotocin in the abdominal cavity to induce diabetes in the female mice.

  伱As long as there is a little deviation in the middle, it does not meet the experimental assumptions you set up, and you can only redo it completely.

   Is it a single money issue at this time? no. Money can\'t buy experimental results. Some scientific research students and teachers are so irritable that they feel the pressure of jumping from a building to a river because the results are not delivered within the planned time.

  Student Xie explained it to Wei like this, which is the most common laboratory question answer.

   Wei, Pan, who has never been in contact with scientific research, was taken aback for a moment. Dai Nanhui seriously questioned again: Are Xie\'s parents really ordinary people?

   "You said that, Yingying, the most important thing is—" Wei Shangquan asked.

   looked back and said that someone had just questioned their classmates, including her, Xie Xie, for being proud of their talents. Now it seems that on the contrary, Xie respects each supervisor because he understands scientific research too much, and does not want to cause trouble for his supervisor, so he must choose carefully.

   If you want to avoid detours, it is not in vain. The preliminary experimental design is the most important. This requires guidance from yourself and a mentor who has the same idea. So what Senior Sister Yu said at the beginning was the most correct.

  The surroundings were too quiet, and a few students looked up and realized that the seniors were eavesdropping on them at some point, and immediately put their voices away.

  Cheng Yuchen and Duan Sanbao looked at each other: the boss\'s expressions and eyes were not quite right.

   Not long after, Xie Wanying could feel a meaningful glance from the foresighted and dark-bellied eyes of the immortal brother in front of her, which made people\'s heart skip a beat.

   This classmate Xie is really surprising. A person who seems to have no experience in scientific research actually understands scientific research. What is going on? The most outrageous thing is that many people should have known about it and didn\'t tell him. No wonder a bunch of people grabbed it.

   Thank you for your support! ! Good night dears~
