摘　　要：本文分别研究了子半群格是0-分配格和0-模格的π-正则半群,特别地,还刻划了子半群格是0-模的有补格的π-正则半群。In this paper,the author studies the π-regular semigroups which lattices of subsemigroups are 0-distributive lattices or 0-modular lattices,in particular,characterises the π-regular semigroups which lattices of subsemigroups are 0-modular are complemented.
