摘　　要：考虑度量空间中离散动力系统的混沌,改进了两条现有判据,证明了当一个系统有正则退化snap backrepeller时拓扑共轭于符号动力系统.Chaos of discrete dynamical systems in metric spaces was discussed.Two existing criteria for chaos was improved,and it is proven that a system was topologically conjugate to a symbolic dynamical system if it has a regular degenerate snap-back repeller.

关 键 词：度量空间 离散动力系统 混沌 SNAPBACK REPELLER
