带强迫项变系数组合KdV方程的有理展开式精确解

Exact solution of rational expansion method to the variable coeffcient combined KdV equation with forced term

利用符号计算软件Maple,在一个新的广义的Riccati方程有理展开法的帮助下,求出了带强迫项变系数组合KdV方程的有理展开式的精确解,该方法还可被应用到其他变系数非线性发展方程中去.

With the aid of symbolic computation system Maple, several new kinds of generalized exact solutions for the variable coefficient combined KdV equation with forced term are obtained by using a new generalize Riccati equation rational expansion method. This approach can also be applied to other variable coefficient nonlinear evolution equations.
