摘　　要：利用单向S-粗集对偶,给出单向S-对偶粗决策规律生成方法;给出上决策规律,下决策规律,单向S-对偶粗决策规律核,单向S-对偶粗决策规律带的概念.利用这些概念,提出下决策规律传递定理,上决策规律传递定理,-F-分离的属性定理,粗决策规律挖掘定理与粗决策规律挖掘准则.By using the dual of one direction S-rough sets, a generation method of one direction S-dual rough decision law was presented and the concepts of upper decision law, lower decision law, one direction S- dual rough decision law kernel and one direction S- dual rough decision law band were proposed. Then by using these concepts, the theorem of lower decision law transfer, the theorem of upper decision law transfer, the theorem of F-separation attribute, the theorem of rough decision law mining and the rough decision law mining criteria were presented.

关 键 词：单向S-粗集对偶 单向S-对偶粗决策 规律挖掘准则 粗决策规律 粗决策规律带
