摘要
利用齐次平衡原则,推导出变系数KdV方程组的Bcklund变换,并借助于 该变换,求出了变系数KdV方程组的精确解,并且得出方程的变系数不改变孤立 波的形状,却改变孤立波的波速。
By using homogeneous balance principle , the B■cklund transformations to the coupled KdV equations with variable coefficients are derived if the coefficients of the equation are linearly dependent. Based on the B■cklund transformation , a solitary wave solutions with variable propagation velocity are obtained.
