摘要
A cosmologicM model in which the universe has its critical density and gravitational constants generalized as coupling scalars in Einstein＇s theory is considered. A general method of solving the field equations is given. An exact solution for matter distribution in cosmological models satisfying G = G0（ R/ R0）^n is presented. Corresponding physical interpretations of the cosmological solutions are also discussed.
