摘要：
In this article, we investigate a spatially homogeneous and anisotropic Bianchi type VI0 cosmological model in the presence of dark energy fluid and an attractive massive scalar field in Einstein's theory of gravitation. The field equations are solved using the following conditions (1) scalar expansion is proportional to shear scalar of the space time and (2) a power law between the scalar field and the average scale factor of the universe. We have evaluated the cosmological parameters of the model and discussed their dynamical aspects with reference to the recent discovery of accelerated expansion of the universe.
