摘要：
By means of the real-time Green's functions method with a pair cutoff approximation up to the second order, the thermal fluctuation effects of meson fields on quantum hadrodynamics are investigated. We find that the fluctuation effects of saturation energy, effective mass of nucleon, and the pressure are considerable in low baryon density regions and/or high temperature regions. The results given by pair cutoff theory and by mean field theory are compared.
