层次内P-集合及其性质

The Property of Hierarchy Internal P-sets

P-集合是由内P-集合X^F(internal packet setsX^F)与外P-集合X^F(outerpacket setsX^F)构成的集合对,或者(X^F,X^F)是P-集合.利用P-集合理论,给出内P-集合的扩展模型—层次内P-集合,把内P-集合的依赖关系扩展到层次内P-集合中,并研究层次内P-集合的性质.层次内P-集合是普通内P-集合的扩展,提供了多角度、多层次分析和研究问题的方法.

P-sets are a set pair which are composed of internal P-setsXFand outer P- setsXF,or （XF,XF） is P-sets. By using P-sets, the expansion of the P-sets model--the hierarchy internal P-sets ware given, extend the dependency the hierarchy internal P-sets and study the property of the nature of the P-sets. The hierarchy internal P-sets is the dependency of common internal P-sets t, which provide ways to analysis and research the problem from multi-angle, multi-level.
