摘要 在定义一般模糊关系下的模糊T-近似的基础上,用模糊T-近似算子来刻画模糊关系的自反性、对称性、T-传递性等性质,并讨论了模糊T-粗糙集的一些性质。 We define fuzzy lower and upper T-approximations based on a general fuzzy relation. By means of fuzzy T-approximation operators, the properties of fuzzy relation, sueh as reflexivity, symmetry and T-transitivity ete, are eharaeterized. Some properties of fuzzy T-rough sets are discussed.
