Approximate solution of 2-soliton for generalized disturbed mKdV coupled system
一个广义扰动mKdV耦合系统2极孤子的近似解

The approximate solution for a class of disturbed mKdV coupled system is considered taking a simple and valid technique. We first solve approximate solution of the 2-soliton for a corresponding complex-valued differential equation using the variational iteration method. And then the approximate solution of the 2-soliton for a original disturbed mKdV coupled system is obtained.
