摘　　要：Ｌｉｅｎａｒｄ系统是一种基本的微分系统，但对Ｌｉｅｎａｒｄ系统拓扑分类问题，至今尚没有系统的研究工作，为此对Ｌｉｅｎａｒｄ系统做一个粗分类。The Lienard systems are the most fundamental differental systems, but up to now, the problem of topological classification to the Lienard systems has not been systematically studied yet. In this paper, a rough classification is given at first, which is a preparing work to the topological classification.

关 键 词：拓扑分类 粗结构 林纳系统 微分系统 极限环
