| 摘 要： | 将集合论中的覆盖概念抽象到完全分配格L上,利用它定义格L上关于覆盖的上(下)近似算子,给出格L上覆盖粗糙集模型.文中先讨论格L上覆盖的相关性质,进而研究了覆盖上(下)近似算子的性质,得到若干结果.

| Abstract: | The concept of covering on a complete distributive lattice L is introduced. the upper and lower approximation operators are defined by covering. This paper gives a kind of covering rough sets model over L, and further discuses some properties of these operators. Some results can be obtained. |
