摘要
从扩展非线性薛定谔方程出发 ,重点考虑了五次非线性对调制不稳定性的影响 与过去的研究结论对比发现 ,五次非线性影响着调制不稳定性发生的条件。
It have been calculated effected on modulational instability of quintic nonlinearity from extended nonlinear Schrdinger equation in the papers. Contrasting to the former conclusion, it is found that quintic nonlinearity affects the condition of producing, the ranges of spectrum and the values of gain of modulational instability.
