利用相似变换和直接方差分析的方法，导出了一类变系数广义非线性Schrödinger方程的类有理函数精确解析解。在此基础上，通过选择合适的函数构造了几种新型的光孤立波，并通过计算机仿真用一些有趣的图形展示了这些波的主要演化特征。
We derive two types of exact analytical solutions in terms of rational-like functions for a generalized nonlinear Schrödinger equation with variable coefficients via the methods of similarity transformation and direct ansatz. Based on these solutions, several novel optical solitary waves are constructed by selecting appropriate functions, and the main evolution features of these waves are shown by some interesting figures with computer simulation.
