该文引入半Smooth格和半Smooth代数格的概念,讨论它们的一些基本性质及与半连续格的关系,证明了完备格L是半Smooth格和半连续格当且仅当L是完全分配格.
In this paper, the concepts of semi-Smooth lattices and semi- Smooth algebraic lattices are introduced. Some basic properties of them and the relation with semi-continuous lattices are investigated. It is proved that a complete lattice is completely distributive lattice if and only if it is both semi-Smooth lattice and semi-continuous lattice.
