摘　　要：利用平面动力系统理论对Zakharov-Rubenchik方程进行了定性分析,并利用待定系数法和指数函数展开法导出了Zakharov-Rubenchik方程的钟状解和扭状孤波解的精确表达式。The Zakharov-Rubenchik equation was qualitatively analyzed by using the theory of planar dynamical system; and the exact expression of new bell solution and torsional solitary wave solutions of Zakharov-Rubenchik equation were obtained by using method of indeterminate coefficients and method of exponential function expansion.

关 键 词：Zakharov-Rubenchik方程 平面动力系统 待定系数法
