摘　　要：We investigate the one-dimensional nonlinear SchrSdinger equation with a perturbation of polynomial type. The approximate symmetries and approximate symmetry reduction equations are obtained with the approximate symmetry perturbation theory.We investigate the one-dimensional nonlinear SchrSdinger equation with a perturbation of polynomial type.
