Abstract：
The finite temperature real time Green's function method with normal pair cutoff and abnormal pair cutoff approximation is applied to derive the equation of state and the energy gap equation for nuclear matter with the Gogny D1 effective interaction.The critical temperature for liquid-gas phase transition and for superconducting phase transition are found to be 14.8MeV and 0.2MeV respectively.The energy gap is determined by the finite range part of the Gogny D1 interaction only.
