　　研究决策表的正域约简及分配约简理论。针对具有自反性的广义不可区分关系，提出了决策表的正域约简及分配约简理论，借助区分函数给出了正域约简及分配约简的计算方法。对Skowron的区分条件进行了改进，在一定意义上为正域约简及分配约简提供了一般理论框架。

This paper is devoted to the discussion of positive region reduction and distribution reduction of decision tables .With respect to generalized indiscernibility relation , the approaches for positive region reduction and distribution reduction are presented by using discernibility functions.Skowron’s discernibility condition is improved.The approaches proposed in this paper provide a general framework for the reduction of decision table .
