Abstract：The observational constraints on viscous generalized chaplygin gas ( VGCG) model is mainly re-searched .As an extension of our work before , the perturbation of viscosity is considered .Through comparing the results of two different cases , the following conclusion is obtained:the result is more rigorous when the perturba-tion of bulk viscosity is included .
