摘    要:在这篇文章里主要研究了广义仿紧空间的遗传性和基-正规性.着重证明了:(1)设X=(lim){ Xα,παβ,∧},|∧|=λ,每一个投射πα是开的且到上的,X为(遗传)λ-仿紧的,若每个Xα是可遮的,则X是(遗传)可遮的.(2)设X是基-正规空间,Y是可度量空间,则当且仅当X×Y为基-正规空间时X×Y为正规空间.

关 键 词:λ-仿紧  可数仿紧  遗传性  基-正规

Abstract:This paper is made of the hereditary property and the base-normality of generalized paracompact spaces. It is proved emphasizely that: (1) Let X= lira { Xa, A }, [ .4 ] = A, each projection a X=Xa is an open and onto map, X is (hereditary)k--paracompact, suppose each X. is screenable, then X is (hereditary) screenable. (2)Let X be a base-normal space and Y a metrizable space. Then, the product space XXY is normal if and only if X X Y is base-normal.
Keywords:λ-paracompact countably-paracompact space  hereditary property base-normality
