摘要
借助数学软件Mathematica,利用基于Lamé方程和Jacobi椭圆函数展开法的小扰动方法求得了Zakharov方程的多级包络周期解,极限情况下它们退化为各种形式的包络孤波解.
With the aid of computer algebraic system ——Mathematica, the multi-order envelope periodic solutions of Zakharov equation are obtained by using the perturbed method, which are based on Lamé equation and Jacobi elliptic function expansion method. These multi-order envelope periodic solutions can degenerate into different envelope solitary wave solutions.
