中文摘要：

P-集合（packet sets）是一个动态模型,P-集合是由内P-集合X~F（internal packet set X~F）与外P-集合（outer packet set X~F）构成的元素集合对;或者（X~F,X~F）是P-集合.利用内P-集合与信息融合交叉,给出内P-信息融合概念,给出一些基本理论结果,并利用这些特性进行信息过滤-辨识.最后利用这些结果给出应用.

英文摘要：

P-sets（packet sets） is a set-pair composed of internal P-set XF（internal packet set XF） and outer P-set XF（outer packet set XF）, or （XF,XF） is P-sets, which has the dynamic characteristic. Under a certain condition, P-sets （XF,XF） can be recovered to finite general set X. By using P-sets, generation of internal P-information fusion, the dependence theorem of internal fusion, internal P-infor- mation generation theorem, information sieve-filtration theorem. Using those results, application is shown.
