对用齐次平衡法求解非线性发展方程精确解的若干文献进行了分析.发现了一个线性偏微分方程.以这个线性方程作为辅助方程,并与齐次平衡法相结合.求得Burgers方程和水波长波近似方程等一些非线性发展方程的新的精确解,推广了齐次平衡法的应用.
Based on the auxiliary equation method combined with the homogeneous balance method,a modified homogeneous balance method was proposed to construct the exact solutions of some nonlinear evolution equations. As examples, Burgers equation and approximate equations for long water waves were investigated and their various new exact solutions explicitly obtained.
