Abstract：
In this paper, the fomulations of the energy density and pressure density of nuclear matter are derived in detail in one loop approximation in the relativistic σ-ω model. The changing of the binding energy and pressure with density is calculated numerically, and the pressure density is calculated in thermodynamics and hydrodynamics respechvely. We conclude that the pressure density in these two formalisms are similar.
