临床研究工作是比较难的,因为其对象是人,这与在实验室做实验或在动物模型上进行试验不同,失败了可以重做。临床研究是不允许用人来做试验的。病可以治不好,但决不允许治坏,这是做医生的准则。此外,人也不同于机器,同一牌号的机器其构造是完全相同的,只要检出毛病,可以拆下修理 Clinical research is more difficult because its target is human, which is different from experimenting in a laboratory or experimenting with an animal model. Failure can be redone. Clinical research does not allow people to experiment. The disease can not be cured, but it will not be allowed to cure it. This is a guideline for doctors.
