摘要：

This paper presents cosmological models in which the gravitational and cosmological constants C and A are time-dependent. We find a variety of solutions for the variation of cosmological parameters. It is also found that, in the case of matter dominated Robertson-Walker Universe, if the cosmological constant. A not equal 0, the Hubble's constant H is not constant at all but inversely proportional to the cosmic time. The conservation law for the energy momentum tensor is still valid with our law of variation: A alpha R-2 and G rho alpha A/8 pi.
