中文摘要：

利用（G′／G）-展开法，构造经典的 Drinfel′d-Sokolov-Wilson方程的新的非线性波解。这些非线性波解分别以双曲函数、三角函数和分式函数的形式表达。结果表明：（G′／G）-展开法是研究数学物理方程的非线性波解的一种有效工具。

英文摘要：

We constructed new nonlinear wave solutions for the classical Drinfel′d-Sokolov-Wilson Equation by exploiting （G′/G）-expansion method.These nonlinear wave solutions are expressed in the forms of the hy-perbolic functions,the trigonometric functions and the rational functions.The results show that （G′/G）-ex-pansion method is an efficient tool for studying nonlinear wave solutions of mathematical physics equations.
