本文基于Jacobi椭圆函数和Lam6方程,应用摄动法研究了非线性与立方非线性Schrodinger方程,获得了其新的多级包络周期解.这些解在极限条件下可以退化为各种形式的包络孤波解.
Based on Jacobi elliptic function and the Lam6 equation, the perturbation method is applied to get the multi-order envelope periodic solutions of the nonlinear Schrodinger equation and cubic nonIinear Schrodinger equation. These multi-order envelope periodic solutions can degenerate into the different envelope solitary solutions.
