摘　　要：从含修正项的非线性薛定谔(MNLS)方程出发,采用变分法,推导出在三阶色散情况下类明孤子参数随传输距离的演化方程组及其解析解,研究了三阶色散对光纤中类明孤子传输特性的影响。From the MNLS equation and variational method to derive the evolution equations for the parameters of the optical soliton - like pulses and their analytic solutions. The influence of the third - order dispersion on the propagation properties of the optical soliton- like pulscs in optical fibers is discussed .
