摘　　要：用行波变换将Davey-Stewartson方程化为非线性常微分方程,然后分别应用双曲正切函数展开法和双曲正割函数展开法求出其孤立波解,结果与文献[6]一致.After Davey-Stewartson equation is reduced into nonlinear ordinary differential equation through traveling wave transformation,its solitary solutions are obtained by hyperbolic tangent function expansion and hyperbolic secant expansion,which are the same as the result of Literature[6].

关 键 词：DAVEY-STEWARTSON方程 双曲函数展开法 孤立波解
