引入效应代数的直觉模糊滤子和它的水平滤子的概念,讨论了直觉模糊滤子与水平滤子间的关系,给出了直觉模糊滤子的等价描述,研究了直觉模糊滤子的几个运算性质。在两个经典效应代数的效应态射与效应同构意义下,讨论了这种直觉模糊滤子的像和前像问题。
The notions of intuitionistic fuzzy filters and its level filters of effect algebras are introduced, the relations between intuitionistic fuzzy filter and level filter are discussed, The equivalence descriptions of fuzzy filters are given, several operational properties of of effect algebras are studied. In the sense of effect morphism and effect isomorphism between two classical effect algebras, the image and preimage of this kind of intuitionistic fuzzy filters are discussed.
