| 摘 要： | 主要从单模光纤传输模型——常系数和变系数非线性薛定愕方程出发，运用最近得到发展的求精确解的扩展的双曲函数法、F-展开法、基于AKlVS技术的DarbOUX变换方法等方法和求数值解的Adomian分解方法，求得了孤波解，研究了基本光孤波和双孤波在单模光纤中的传输情况，为进一步实现超高速、大容量的光信息传输提供一定的理论依据．

| Abstract: | Starting from nonlinear Schrodinger equations with the constant coeficients, we derive the solitary wave solutions of these equations with the help of the methods including the extended hyperbolic function method, the F-expansion methothe Darboux transformation based on Ablowitz-Kaup-Newell-Segur（AKNS） technology and the Adomian decomposition method, and investigate the properties of propagation of fundamental solitary waves and two-solitary waves in monomode optical fiber. |
