| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
