摘要
发展了一种以分离变量为基础的孤子微扰的直接方法 .借助这种方法 ,得出了微扰对Kdv -Mdv孤子的一级效应 .即 。
We develop a direct approach to the soliton perturbation based on the separation variables.With the aid of this approach,the first order effects of perturbation on a KdV MKdV soliton are derived,namely,both the slow time dependence of the soliton parameters and the first order correction are obtained.
