利用 P-集合，给出 P-集合的粒度概念，讨论了 P-集合粒度的特性，给出粒度与包度的关系定理、粒度的分解定理以及单调性定理。定义了 P-知识以及知识分辨度概念，将 P-集合概念及其粒度特性应用于 P-知识的辨识发现中，得到 P-知识的辨识发现定理。最后将辨识发现定理应用于系统状态的检测识别，给出了系统状态检测-识别准则及其应用。
利用 P-集閤，給齣 P-集閤的粒度概唸，討論瞭 P-集閤粒度的特性，給齣粒度與包度的關繫定理、粒度的分解定理以及單調性定理。定義瞭 P-知識以及知識分辨度概唸，將 P-集閤概唸及其粒度特性應用于 P-知識的辨識髮現中，得到 P-知識的辨識髮現定理。最後將辨識髮現定理應用于繫統狀態的檢測識彆，給齣瞭繫統狀態檢測-識彆準則及其應用。

By using P-sets, the concept and properties of granulation degree in P-sets is presented.The relation theo-rems between the granulation degree and packet degree, the decomposition theorems and the monotonicity theorem of the granulation degree are proposed.P-knowledge and its discernibility degree are defined.P-sets and the properties of the granulation degree are applied to discernibility-discovery of P-knowledge, and the discernibility-discovery theorems of P-knowledge are obtained.Finally, the discernibility-discovery theorems are applied to system state detection-recog-nition, and the criterion of system state detection-recognition and its application are given.
