摘要：

The relativistic nuclear mean-field model with derivative scalar coupling suggested by Zimanyi an Moszkowski is extended to finite temperature by means of the real-time Green's function method with a pair cutoff approximation. The temperature and density dependences of the nucleon masses are given. The obtained equation of state is used to discuss the liquid-gas phase transition of nuclear matter. The critical temperature and density given by this model are kT(C) = 16.51 MeV and rho(C) = 0.0675 fm-3 respectively.
