The significance of graduate students' interpersonal communication can be manifested in three aspects: study, work, life and psychology. From the perspective of study and work, I found that engineering students obviously have some previous study habits, and many problems like to bury their heads in hard work. Many times, they just bow their heads and don't want to look up at the sky. I will not or rarely take the initiative to exchange my learning experience and some ideas with others. From the selection of learning reference materials to the discussion of research problems, I lack the necessary learning (academic) communication. It is right to advocate independent research, but appropriate communication is equally important. Sometimes it can solve the maze for yourself, and sometimes it can play the role of turning war into friendship. Take the initiative to communicate with people who are longer than yourself and walk with them, and you will find that some difficulties are not for yourself and you will not be confused; Explore other people's good research habits and ways of thinking for their own use; By adopting good ideas and ideas, you can point out the direction for yourself in the next study. Today's society is an era of high-speed information. It is impossible to grasp one's own learning and research direction alone and behind closed doors. After all, a person's ability is thin, and proper communication will add wings to himself and avoid detours.
