The notion of base-countably paracompact space is introduced and some of its equivalent characterizations are obtained:(i)X is a base-countably paracompact space if there exsists an open basis B for X with |B|=ω(X) such that every countably open cover U={Ui}i∈N of X has a locally finite countabe refinement B′ by members of B,B′={Bi}i∈N and BiUi.
引入了基-可数仿紧空间的概念,给出基-可数仿紧空间的一些等价刻画,获得以下结果:(i)X是基-可数仿紧空间当且仅当存在X的一开基B,|B|=ω(X),对于X的每一可数开覆盖U={Ui}i∈N,都存在B′B,使得B′={Bi}i∈N是U的局部有限的可数开加细,且BiUi;(ii)设X是正规空间,X是基-可数仿紧空间当且仅当存在的一开基B,|B|=ω(X),使得X的每一可数开覆盖都存在由B中的元构成的局部有限的收缩。

Author mainly proves following:(1)X is a Base-paracompact space iff X is a Base-countably paracompact space and every open cover of X has a σ-locally finite open refinement by members of the basis which witnesses Base-countably paracompact space.
