Abstract: By means of the imaginary time Greer's function method,we extend the One Pion Exchange Potential (OPEP) of nucleon-nucleon interaction to finite temperature.We sum up all the bubble diagrams and find that the temperature effect to OPEP is small at low temperature region but large at high temperature region.The effective mass of pion field Mπ(β) will become imaginary at critical temperature Tc=177MeV.It means that the attractive OPEP will disappear at Tc and the phase transition happens.
