研究了一类强非线性发展方程.利用变分迭代方法,首先构造了相应的变分;其次选取了适当的初始近似;再用迭代方法得到了孤波的任意次精度的近似解.
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.
