摘要
把Jacobi椭圆函数展开法扩展到Jacobi椭圆正弦函数、Jacobi椭圆余弦函数和第三类Jacobi椭圆函数,并给出了KdV方程的新的周期解.并且应用这种方法得到的周期解也可以退化为KdV方程的新孤立波解.
In this paper, the Jacobi elliptic function method is extended to the finite eapansion for the apploed Jacobi sine elliptic function, Jacobi cosine elliptic function or the third kind of Jacobi elliptic function to construct the new periodic solutions of KdV equation .The periodic solutions obtained by this method can be reduced to the solitary wave solutions under the linit coneition.
