摘　　要：We show that the conventional renormalization group method can be used to give an analytic description of the evolution of a soliton in a perturbed KdV equation. The renormalization group equations describe the deformation of the soliton as the effect of perturbations. The method is concise and easy to understand and the results obtained agree with the results of other approaches.We show that the conventional renormalization group method can be used to give an analytic description of the evolution of a soliton in a perturbed KdV equation.
