Abstract: By using Cantor’s sets, Packet sets were presented and called P-sets in brief. P-sets are composed of interior P-sets X and outer P-sets XF. The structure of P-sets and the relation between P-sets and Cantor’s sets were given. P-sets have dynamic characteristics. Under a static-dynamic environment, Cantor’s sets are the special case of P-sets, while P-sets were the general case of Cantor’s sets; and the interior P-decomposition theorem and outer P-decomposition theorem of P-sets were proposed. By using P-sets, integration knowledge, the structure of integration knowledge, and the applications of P-sets in dynamic knowledge discovery were given.
