Abstract:

P-sets(packet sets) are composed of internal P-sets X(internal packet set X) and outer P-sets XF(outer packet sets XF). P-sets have dynamic characteristics. Based on P-sets, the concepts of internal-data circle, outer-data circle are given. By using these concepts, dynamic data recovery theorem, dynamic data recovery guideline and data recovery-identification, as well as applications are proposed. P-sets are new tool to study dynamic data analysis-identification.

Key words:  P-sets; internaldata circle; outer-data circle; outer-recovery; outer-recovery theorem
