摘　　要：用分步富里叶变换法求解Kerr系数随机变化的光孤子NLS方程 ,发现Kerr系数随机扰动对单孤子传输的影响较小 ,对双孤子传输的影响较大 。The properties of propagation of soliton with Kerr coefficient distributing randomly are studied numerically.The results show that the effect on single soliton is smaller than on two solitons.The second-order dispersion distributing randomly can overcome the effect of Kerr coefficient distributing randomly on two solitons.
