摘　　要：在模糊系统中,模糊蕴涵与某些特定的聚合函数(如三角模、三角余模、一致模、零模、半一致模、半t-算子等)间的分配性被广泛研究。作为两类特殊的聚合函数,重叠函数和分组函数因其在图像处理、分类和决策等方面的应用而被广泛关注。本文给出了有加法生成子对的重叠函数、分组函数与具有边界条件的二元函数满足蕴涵分配性方程I(O(x,y),z)=G(I(x,z),I(y,z))的充要条件,以及有加法生成子对的分组函数G1,G2和具有边界条件的二元函数I满足蕴涵分配性方程I(x,G1(y,z))=G2(I(x,y),I(x,z))的充要条件。Among the researches of the fuzzy system,the distributivity between fuzzy implications and some special aggregation functions(e.g.t-norms,t-conorms,uninorms,t-operators,semi-uninorms and semi-t-operators)has been studied by many authors.Overlap functions and grouping functions have been followed with interest for their applications in image processing,classification problems and decision making based on fuzzy preference relations.In this paper,we give necessary and sufficient conditions for two distributivity equations I(O(x,y),z)=G(I(x,z),I(y,z))and I(x,G1(y,z))=G2(I(x,y),I(x,z)),where O is an additively generated overlap function,G1 and G2 are additively generated grouping functions and I is a binary function satisfying boundary conditions.
