外P-信息与它的反动态特性

Outer P-information and its anti-dynamic characteristic

摘要:P-集合(packet sets)是由内P-集合XF(internal packet set X珔F)与外P-集合XF(outer packet set XF)构成的元素集合对;或者,(XF,XF)是P-集合;P-集合具有动态特性。利用外P-集合XF的结构与动态特性,对它的反动态特性给出研究,提出了基信息、外P-信息、F-补充信息、外P-反动态信息的概念;利用这些概念给出几个基本理论结果,利用这些基本结果,给出外P-反动态信息在信息系统中的应用。

P-sets（packet sets） is an element set pair composed of internal P-set X（internal packet set X） and outer P-set XF（outer packet set XF）, or （X,XF） is P-sets, and it has the dynamic characteristic. Using the structure and dynamic characteristic of outer P-set XF and studying its anti-dynamic characteristic, the concepts of basis information, outer P-information, F-supplemented information, outer P-anti-dynamic information are given. Based on the concepts, a few of theory results are proposed, by which the application of outer P-anti-dynamic information in the information system is given.
