研究生阶段有多重要？《Science》有一次专访，我特意借此来谈谈研究生对于一个人的发展是非常重要的。他们几个人都非常公认的一条是：研究生是决定人以后成就高低的一个分水岭。-How important is the graduate level? " Science"　has an interview, I deliberately take for a person to talk about the development of graduate students is very important. They are very few people accepted one is: graduate students who later decide the level of achievement of a watershed.
