摘      要:Two sets of solution of the Einstein’s equations of general theory of relativity which is spherically-symmetric and nonstatic homogeneous isotropic universe for perfect fluid are *** first solution is the Einstein de-Sitter type containing a scale factor(√6πкGt+a)^(4/3)and an arbitrary function f(R)of radial space *** second solution is for stiff equation of state p=ρc2,which also has a scale factor[3√8πaG∫^(t)_(0)ξ(t)dt]^(2/3)and an arbitrary function h(R)of radial space coordinates.
