%X The classification and reduction are the important objectives of rough set theory. According to the properties of partition and merging, the hierarchy relation among condition classification, reduction and core is studied. Based on merging thought, the impact of condition class merging to consistence of decision table is described, then the sufficient and necessary condition about algebra core attributes is proved.
