在前面的一篇文章中，我们发展了由经典的模逻辑的菱形算子和盒算子定义的逼近算子的公理刻画。利用模糊粗糙集的概念定义了近似算子，得到了类似的结果。
In a previous paper we have developed an axiomatic characterization of approximation operators defined by the classical diamond and box operator of modal logic. The paper presented contains the analogous results of approximation operators which are defined by using the concepts of fuzzy rough sets.
