在辅助方程法的基础上,给出辅助方程和函数变换相结合的一种方法,并借助符号计算系统Mathematica,获得了变系数组合KdV方程的新的孤立波解和三角函数解。这种方法在寻找其它变系数非线性发展方程的新的孤立波解和三角函数解方面具有普遍意义。
solutions obtained solutions term Based on the auxiliary equation method, combining with function transformation, new solitary and triangular function solutions of combined KdV equation with variable coefficients term was with the help of symbolic computation system Mathematica. It is of significance to seek solitary and triangular function solutions of other nonlinear evolution equations with variable coefficients
