Secondly, based on the analysis of theoretical scientific research personnel and team, the teamwork motivation model is built, and it is achieved that teamwork improves the team output. Later,we lead the reputation that is regarded inexplicit incentive into the scientific research personnel"s utility function, establish a model of their reward, analyze the parameter of reputation"s effect to factor in the contract. After that, it analyses traditional training object selection and whole training object selection among the scientific research team to draw the conclusion that the traditional training object selection has obvious limitations and the whole training has evident advantages. In the end, based on the theoretical study of the psychological contract, we can obtain the effective paths of forming psychological contract among the scientific research team.
