摘要：
An LRS Bianchi type I string dust cosmological model with and without bulk viscosity following a method used by Letelier and Stachel, is investigated. To get a determine solution, it is assumed that sigma proportional to theta where sigma is shear and theta is scalar of expansion and which leads to A = alphaB(n) were n is a constant. The physical and geometrical aspects of the model are also discussed.
