基于覆盖重新定义了Zoom-in算子,通过Zoom-in算子和Zoom-out算子的不同复合分别得到论域及粒化了论域上的近似算子,并将它们与拓扑中的预内部算子、闭包算子建立联系。此外还详细讨论了它们的性质。
基于覆蓋重新定義瞭Zoom-in算子,通過Zoom-in算子和Zoom-out算子的不同複閤分彆得到論域及粒化瞭論域上的近似算子,併將它們與拓撲中的預內部算子、閉包算子建立聯繫。此外還詳細討論瞭它們的性質。

Based on covering, a new Zoom-in operator is presented. Furthermore, a new model of granular computing is investigated. Different rough approximations of the universe of discourse and granulated universe of discourse are obtained by different combinations of Zoom-in and Zoom-out operators. Then we established the relation that they and topology of preliminary internal operator, closure operator. In addition, their properties are discussed in detail.
