摘　　要：基于描述光学暗孤子的NLS方程的守恒律,研究了单模光纤中微扰对基黑孤子脉冲传输特性的影响,导出了基黑孤子参数的演化方程组,从其出发讨论了光纤小损耗、三阶色散和内脉冲拉曼散射(IRS)等效应.Influence of perturbation on the fundamental black soliton propagation is investigated by means of conservation laws of NLS equation in monomo-de optical fibers, and general equations for evolution of the fundamental black soliton parameters are obtained. Small dissapative, third-order dispersion and Raman scattering are discussed.
