Outer P-information generation and its reasoning-searching discovery

P-equivalence class(packet equivalence class) is obtained by using P-sets(packet sets).P-equivalence class is an equivalence class pair composed of internal P-equivalence class [x] and outer P-equivalence class,or,(F) is P-equivalence class,which has the dynamic characteristic.Under a certain condition,P-equivalence class can be restored to the general equivalence class [x].The measure of P-equivalence class and discrete interval theorem of measure are given.Using P-equivalence class and P-reasoning,the reasoning discovery of the unknown P-information and discovery theorem are presented.Based on the results,the application of reasoning discovery of outer P-information in information system is given.
