摘要：
The scattering of a soliton by an impurity in the discretized nonlinear Schrodinger equation is studied numerically. The reflection coefficient is obtained as a function of the strength of the impurity potential. It is shown that the scattering of a soliton depends mainly on the strength of the impurity potential, but not on the soliton width.
