KdV-MKdV equation%soliton%perturbation
The authors develop a direct approach to the soliton perturbation based on the separation of variables.With the aid of approach,the first-order effects of perturbation on a KdV-MKdV soliton are derived,both the slow time-dependence of the soliton parameters and the first-order correction are obtained.
