摘要
首先将偶合KdV方程变换为双线性形式 ,然后假定它的特殊孤子解的形式 ,得到一组方程 ,并通过Mathematica软件来对它进行符号计算 ,求出它的四孤子解 .借助Matlab软件还可作出解的图形 .
The coupled KdV equation is tr anslated into bilinear form.After the form of their soliton solution is given some equations are obtained.It is caculated by the Mathematica software and the four-soliton solution is solved.The graphs of solutions are also suggested.
