From pulse shape and spectrum,the influences of the third-order dispersion,self-steepening and intrapulse stimulated Raman scattering on the propagation property of the high-order solitons are analysed.

从脉冲形状和频谱两个方面分析讨论了三阶色散、自陡峭效应和脉冲内拉曼散射对高阶孤子传输的影响。

This paper using the symmetrical split-step Fourier′ method simulates the pulse of high-order solitons transmission characteristic in self-steepening effect and broadening of pulse and spectrum situation.

采用对称分步傅里叶法数值模拟了高阶孤子在自陡峭效应的影响下,脉冲传输特性及脉冲和频谱展宽情况。

The numerical results show that the self-frequency shift and self-steepening make the pulse drift backward nonlinearly,and the drift of the former pulse smaller than that of the latter.

数值结果表明:自频移和自陡峭都使脉冲向后沿呈现非线性的偏移,前一个脉冲的偏移量很小,基本上是呈线性偏移,后一个脉冲随传输距离的增加,偏移量逐渐的增大,呈非线性偏移。

First,through the basic principle proof and algorithm inferential reasoning, the steep and kurtosis analytic method and the logarithm power spectrum correlation function analyzing method are proposed, which are suitable to revolve the initial faults of rotating machinery.
