本文基于高阶非线性薛定谔方程，数值研究了自陡峭效应和拉曼增益对啁啾Peregrine怪波传输特性的影响。结果发现，随着自陡峭效应的增强，啁啾Peregrine怪波的分裂变得不再规则，且分裂后脉冲中心位置发生偏移；拉曼增益效应的增加会导致啁啾Peregrine怪波分裂后一侧子脉冲的峰值功率增加明显。

Based on higher-order nonlinear Schrdinger equation,we numerically studied the influence of the self-steepening and Raman gain effects on the propagation properties of the chirped Peregrine solitons. Results showed that the chirped Peregrine solitons splited irregularly and the pulse center moved with the enhancement of self-steepening effect. The increase of Raman gain effect can cause the obvious increasing of the peak power on one side of the splited pulse.
