摘　　要：引入格的对偶半同态与对偶半自同态,并利用格的对偶半同态与对偶半自同态研究粗糙集的代数性质,统一了多种类型的粗糙集.Dual senti homomorphism and dual semi-homomorphism and dual semi-h unity some type rough set are discussed. dual semi-self-homomorphism of lattice is induced. By means of the omomorphism of lattice,some properties of algebra for rough set and

关 键 词：格的对偶半同态 格的对偶半自同态 二元关系 粗糙集
