采用了一个简单而有效的技巧,研究了一类扰动mKdV耦合系统.首先利用变分迭代方法求解一个相应的复值函数微分方程2-极孤子的近似解.然后得到了原扰动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.
