针对最近发现的高阶非线性薛定锷方程的组合孤波解,我们数值研究了它在受到包括幅度偏离、参数条件偏离以及随机噪声等不同初始扰动后的传输特性.结果表明一定的精确脉冲在不同的扰动下有类似的稳定趋势.

Aiming at the Combined Solitary Wave for the higher-order nonlinear Schrdinger equation (HNLSE) discovered recently, we investigate its propagation characteristic against some small perturbations such as amplitude variations, violation of parameter conditions and random noise by employing numerical simulation. The results show that for different perturbations, the propagation of the combined solitary wave has a similar stability trend for a certain initial pulse.
