摘要

摘要: 研究了一个强非线性波动方程.利用泛函分析变分迭代方法，首先构造了一个变分, 求出相应的Lagrange乘子；其次构造一个解的变分迭代, 选取初始孤子波；最后利用迭代方法依次求出各次孤子波的近似解.该方法是一个简单可行的近似求解非线性方程的方法

Abstract: A strongly nonlinear wave equation was studied. With the functional analytic variational iteration method, firstly, a variational iteration was constructed, and the corresponding Lagrangian multiplicator was solved. Secondly, the initial solitary wave was selected and the iteration method was used to obtain the approximate solution of arbitrarydegree accuracy for the solitary wave. This method is easy and feasible for getting approximate solutions to nonlinear wave equations.
