摘要: 把变量分离法应用于(1+1) 维非线性物理模型,构建了色散缓变光纤变系数非线性薛定谔方程的一类新的孤子解.作为特例,也得到了常系数非线性薛定谔方程的包络型孤子解,只是解的形式有点变化.

Abstract: In this paper, a variable separation approach is proposed and successfully extended to the (1+1)dimensional physics models. The new exact solution of two classes of variable-coefficient nonlinear Schrdinger equations are obtained. As a specific example, the envelope soliton solution for nonlinear Schr?dinger equations are a by-product, which is somewhat different in form, from the present result. -
