Abstract: Inverse P-sets (packet sets) are a pair of element sets composed of internal inverse P-set F (internal inverse packet set F) and outer inverse P-set (outer inverse packet set ),or () is an inverse P-set．Inverse P-set has dynamic characteristic．Using internal P-set,internal inverse P-reasoning (internal inverse packet reasoning),internal inverse P-information intelligent fusion generation,internal inverse P-information intelligent fusion supplemented generation and internal inverse P-information intelligent fusion measurement,internal inverse P-information intelligent fusion theorem,internal inverse P-information intelligent fusion dependent theorem and internal inverse P-information intelligent fusion recovery theorem were proposed．The attribute disjunctive character and attribute disjunctive expansion theorem of internal inverse P-information intelligent fusion,the attribute disjunctive expansion and unknown internal inverse P-information intelligent fusion discovery theorem recovery theorem were put forward．The application of these theory results was presented．Inverse P-sets is a new theorem and method of studying the other dynamic information application．The dynamic information has attribute disjunctive character.
