英文摘要	We describe a novel numerical approach to simulations of nonlinear Schrodinger equations with varying coefficients, based on the discovery of a new and intrinsic conservation law for varying coefficient nonlinear Schrodinger equations. The approach is shown to preserve some crucial classical conservations, such as the spatial ergodicity, and utilized in numerical simulations of periodically and quasi-periodically solitary waves for nonlinear Schrodinger equations with periodic or quasi-periodic coefficients. Some numerical experiments are presented to illustrate the conservative property. (C) 2003 Elsevier Science Ltd. All rights reserved.
