摘要：

The active mass density in Einstein's theory of gravitation in the analog of Poisson's equation in a local inertial system is proportional to rho+3p/c(2). Here rho is the density of energy and p its pressure for a perfect fluid. By using exact solutions of Einstein's field equations in the static case we study whether the pressure term contributes towards the mass.
