摘　　要：利用P-集合的动态结构,给出伸-离散数据,缩-离散数据与伸-缩离散数据概念、动态生成与存在定理。给出伸-离散数据的属性收缩,缩-离散数据的属性扩展与伸-缩离散数据的属性定理。利用这些概念与结果,给出伸-缩离散数据在数据淹没-隐藏中的应用。Using dynamic structure of packet sets,the concepts,discrete stretching,shrinking and stretching-shrinking data are introduced,and then their dynamic generation and existing are given.Their existence theorems are proposed, and then the attribute shrinking theorem of discrete stretching data,the attribute stretching theorem of discrete shrinking data and the attribute theorem of discrete stretching-shrinking data are put forward.Using these results,the application of discrete stretching-shrinking data in data submerging and hiding is shown.

关 键 词：P-集合 伸-缩离散数据 存在定理 属性定理
