给出一种辅助方程与Riccati方程之间的拟B(a)cklund变换,根据Riccati方程的有关结论并利用符号计算系统Mathematica,获得了由双曲函数、三角函数和有理函数组成的KdV方程的无穷序列新精确解.
The quasi-Baicklund transformation between a kind of auxiliary equation and Riccati equanon is given. According to related conclusions of Riccati equation, new infinite sequence exact solutions com- posed of hyperbolic function, triangular function and rational function to KdV equation are obtained with the help of symbolic computation system Mathematica.
