摘要
该文首先推广了新近提出的F-展开法,利用该方法导出了变系数KdV和mKdV方程的类椭圆函数解;并在极限的情况下,得到变系数KdV和mKdV方程变波速和变波长的类孤子解以及其他形式解.
In this paper, the F-expansion method proposed recently is improved and applied to derive the cnoidal-like solutions of the general KdV and mKdV equations with variable coefficients, In the limit case, the soliton-like solutions with variable propagating speed and amplitude are obtained.
