利用广义变分迭代方法研究了一类非线性发展扰动方程.首先引入一个泛函.然后求其变分,最后构造方程解的迭代关系式.得到了问题的近似解和精确解析解.
Using the generalized variational iteration method,a class of nonlinear disturbed evolution equations are studied. Firstly,a functional is introduced,then its variational is computed,and the iteration expansion is finally constructed. The approximate and exact analytic solutions to the problem are obtained.
