论文摘要
在本文中，介绍了准最终分离图和准磷型身份的概念。基于这些概念，定义了QFS空间和准确的图。探索了QFS空间的属性和特征。主要结果是：（1）每个QFS空间是准确的空间； （2）封闭的子空间，QFS空间的准确投影空间是QFS空间； （3）QFS空间的连续缩回是QFS空间，构建了QFS空间的一种缩回； （4）连续QFS空间的上力空间是FS空间。
In this paper, the concept of quasi-finitely separating map and quasiapproximate identity are introduced. Based on these concepts, QFS-spaces and quasicontinuous maps are defined. Properties and characterizations of QFS-spaces are explored. Main results are: (1) Each QFS-space is quasicontinuous space; (2) Closed subspaces, quasicontinuous projection spaces of QFS-spaces are QFS-spaces; (3) Continuous retracts of QFS-spaces are QFS-spaces and a kind of retracts of QFS-spaces are constructed; (4) Upper powerspaces of continuous QFS-spaces are FS-spaces.
