摘要：
Exact solutions for an anisotropic Bianchi type I model with bulk viscosity and variable G and Lambda are obtained. We have found some solutions that correspond to our earlier work for the isotropic one. Unlike Kalligas et al., an inflationary solution with a variable energy density has been found where the anisotropy energy decreases exponentially with time. There is a period of hyper-inflation during which the energy density remains constant.
