Variational iteration method for solving a class of strongly nonlinear evolution equations
一类强非线性发展方程孤波变分迭代解法

A class of strongly nonlinear evolution equations are studied. Using the variational iteration method, the corresponding varationa is first constructed,then the suitable initial approximation is selected; and then, by using the iteration method, the approximate solution of arbitrary degree of accuracy for the solitary wave is obtained.
