摘　　要：通过齐次平衡方法研究(1+1)维水波方程,得到该方程的二组试探解,并分析其孤波激发模式,找到了三种新类型的孤波结构,即稳定型双孤波结构、非稳定型孤波结构、周期性孤波结构,讨论了孤波变化过程。This paper makes a study of(1+1)dimensional water wave equation with the help of homogeneous balance method,obtains two sets of tentative solutions of the equation,analyzes the excitation mode of its solitary wave,and finds out three new types of solitary wave structures,namely,stable double solitary wave structure,unstable solitary wave structure and periodic solitary wave structure,and discusses the change process of the solitary wave.

关 键 词：(1+1)维水波方程 齐次平衡方法 孤波结构
