引入局部连续Domain的局部基和稠密子集的概念,在此基础上定义了局部连续Domain的特征与浓度.给出了局部基的刻画,并讨论局部连续Domain的特征、浓度与局部连续Domain带上Scott拓扑或局部Lawson拓扑时的拓扑空间的特征、浓度之间的关系.

英文摘要：

The concepts of the local base and dense set of locally continuous Domains are introduced and examined. On the basis of this, the character and density on locally continuous Domains are defined. In addition, some characterizations about the local base are given. The relations between the character and density on a locally continuous domain and those on the related topological space with Scott topology or locally l_awson topology are discussed.
