Do that human communications put in our graduate student this kind of community have some special significances? Before this, I want first to carry on the analysis to graduate student this kind of special community, takes the graduate student, he similarity lies in with the undergraduate student no longer is the pure study, he wants to do more research and the development work, compares says, his research direction wants careful and is single-minded, but must want to yield the result, he must more dedicated, must invest more time and the energy in the research. Under such background, some which in addition originally raids studies investigates the breath, causes him less or is not willing to pay attention to the human communication, the contact scope quite is narrow, some people display relatively closed. Does not stop the charge regarding this kind of expectation development, also the relatively busy community said, the human communication and the communication are does not have the major function? This question myself am understand like this.
