摘　　要：本文采用变分法 ,考虑在五阶非线性情况下 ,修正的NLS方程的类明孤子解的各参数随传输距离的变化特性。结果表明 :五阶非线性情况下 。In this paper,using the variational principle for the optical soliton like pulses in the optical fiber and taking the fifth order nonlinearity into consideration in the modified NLS equation,we investigated the evolution of the parameters of the optical soliton like pulses and we got the conclusion:the influences of the fifth order nonlinearity on the optical soliton like pulse have many differences from that on the bright soliton.
