摘要
利用(W/G)展开法求解变系数KdV方程,得到了很多新的精确解,包括单循环孤立子解、三角周期解、有理函数解等.这些解对解释复杂物理现象具有重要的物理意义.
In this paper, the (W/G)-expansion method is used to solve the KdV equation with variable coefficients . Some new exact solution solutions of the KdV equation with variable coefficients are derived which included single-loop soliton solutions, triangular periodic solutions, rational function solutions and so on. These solutions are important to explain the complex physical phenomena .
