| 摘 要： | 为了研究覆盖上的层次结构问题,在覆盖上提出了知识距离的概念,并由覆盖知识距离构建了两种不同的代数格,最终使用由这两种代数格所诱导出的偏序关系来刻画不同覆盖之间的关系.实例分析表明由知识距离格方法来研究覆盖的层次问题是切实可行的.由此可以看出,知识距离为研究覆盖的层次问题提供了一种新的有效方法.

| Abstract: | In order to research the hierarchy of covering,the concept of knowledge distance is proposed on covering. Moreover,two different algebraic lattices are constructed through the new proposed knowledge distance. Finally,the partial relations induced by such two algebraic lattices are used to characterize the relationships among coverings. The example shows that it is feasible to compare coverings by the knowledge distance approach. Thus,it can be seen that knowledge distance provides a new effective way to research the hierarchy of covering. |
