摘要：

In this paper, we attempt to study spatially homogeneous Bianchi type-I cosmological models in f (R) theory of gravity. The exact solutions of the Einstein's field equations (EFEs) have been obtained by assuming that the expansion theta is proportional to the shear sigma and by using a special form of Hubble parameter (HP). Here we find two exact solutions by using the variation law of H based on two different values of n. The physical and geometrical properties of these models have been discussed and the function f (R) of the Ricci scalar R is obtained for each case.
