摘要：
A plane-symmetric non-static cosmological model representing a bulk viscous fluid distribution has been obtained which is inhomogeneous and anisotropic and a particular case of which is gravitationally radiative. Without assuming any ad hoe law, we obtain a cosmological constant as a decreasing function of time. The physical and geometric features of the models are also discussed.
