用平衡法并结合吴消元法得到了一类较广泛非线性波动方程utt-a1uxx+a2ut+a3u+a4u3=0的若干孤波解公式，从而物理学上许多著名的方程，如φ4方程、Klein-Gordon方程、Landau-Ginzburg-Higgs方程、非线性电报方程等都可作为该方程的特殊情形得到相应的孤波解Some solitary wave solutions for a class of nonlinear wave equations utt－a1uxx＋a2ut＋a3u+a4u3=0 are obtained by homogeneous balance method and Wu-eliminition method. Many well-known equations in physics such as φ4 equation, Klein-Gordon equation, Duffing equation and telegraph equation are special cases of the wave equation presented in this paper.
