摘要
本文利用特定的覆盖性质，建立了仿紧局部紧空间的序列覆盖Ｌ－映象和紧覆盖Ｌ－映象的特征，得到或深化了局部紧度量空间的一些相应结果．
in this paper we establish the characterizations of images of paracompact locally compact spaces under some sequence-covering L-mappings and compact-covering quotient Lmappings by means of the concepts of cs-covers, cs*-covers, sn-covers and k-systems, respectively, and improve some corresponding results on locally compact metric spaces.
