逆P-集合

Inverse P-sets

利用P-集合(Packet sets),提出逆P-集合(Inverse packet sets),给出逆P-集合的结构;逆P-集合记作P-1-集合。P-1-集合是P-集合的对偶形式。P-1-集合是由内P-1-集合X珔F(Internal inverse packet set X珔F)与外P-1-集合X珔F珔(Outer inverse packet set X珔F珔)构成的集合对;或者(X珔F,X珔F珔)是P-1-集合;P-1-集合具有动态特征。给出P-1-集合的分离定理与P-1-集合的动态等价类特性,给出P-1-集合在动态信息系统中的应用。

Using P-sets（packet sets）,inverse P-sets（inverse packet sets） and its structure are presented,which is briefly expressed as P-1-sets.P-1-sets is the dual form of P-sets.P-1-sets is a set pair composed of internal inverse P-set F and outer inverse P-set,or（F,） is P-1-sets,and P-1-sets has the dynamic characteristic.The separation theorem and dynamic equivalence class characteristic of P-1-sets and the application of P-1-sets are given in the dynamic information system.
