对粗糙集上代数结构进行了研究,引入了粗糙除环、粗糙域和粗糙整环等概念。利用粗糙集理论方法和经典代数中的处理手段,讨论了粗糙除环和它们的结构特征,得到了它们的一些良好的性质。
In this paper, the algebraic structure of rough sets are studied. The concepts of rough divided ring and rough field and rough integral ring are introduced. Their structure characteristics those of rough divided ring are discussed and some good characters are produced and proved through the method of rough sets theory and the managing method in sutra algebra.
