几个高阶非线性方程的显式精确解

摘要

This paperhasobtained theexplicit and exact solutions for several higher-order nonlinear equations in usual ways by means of extending a new method for finding the explicit and exact solutions of nonlinear equations. The approach used herein can also be used to construct the explicit and exact solutions to other nonlinear equations.%将一种求非线性方程显式精确解的新方法进行推广，并用它求得几个用通常的方法难以求解的高阶非线性方程的显式精确解。该方法也可用于构造其他非线性方程的显式精确解。
