广义变系数KdV方程新的精确解

New exact solution of the general variable coefficient KdV equation

在截断展开法中,运用新的展开形式,求出广义变系数KdV方程义变系数三种类型新的精确解。由此可见,用这种方法还可以求解一大类变系非线性演化方程。

In truncated expansion method, this paper applies new expansion form and gives three kinds of new exact solutions of variable coefficient KdV equation is given. Form this example we can see that this method is fitted to solve a large number of nonlinear evolution equation.
