摘　　要：在Ｇａｕｓ球面上，讨论了Ｌｉｅｎａｒｄ系统的拓扑分类问题，证明了系统有且只有两个奇点０和∞，及Ｃ类轨线和Ｄ类轨线的可能分布情况．The problem of topological classification to Lienard systems is discussed on Gauss sphere in this paper. It is showed that the system has two and only two singnlar points 0 and ∞. The distribution of C -trajectories and D -trajectories is also discussed.

关 键 词：C类轨线 D类轨线 轨线 林纳系统 拓扑分类
