It follows from one of these characterizations that the pseudo open and compact image of a countably paracompact space is a countably metacompact space.

The present article proves the following results:(1) if X=∏α∈ΛXα is |Λ|-para-closed spaces,then X is meso para-compact if and only if F∈[Λ]<ω,∏α∈FXαis countably paracompact;(2) if X=∏i∈ωXi is countably paracompact,then the following three conditions is equal in value;X is meso compact;F∈[Λ]<ω,∏α∈FXαis meso compact;n∈ω,∏i<nXi is meso compact.

主要證明了如下結果:(1)如果X=∏α∈ΛXα是|Λ|-仿緊空間,則X是meso緊的當且僅當F∈[Λ]<ω,∏α∈FXα是meso緊的;(2)如果X=∏i∈ωXi是可數仿緊的,則下列三條件等價:X是meso緊的;F∈[Λ]<ω,∏α∈FXα是meso緊的;n∈ω,∏i≤n Xi是meso緊的。

If each Xα is a normal countably paracompact space,then X is a countably paracompact space.

得到了如下結果:設X是逆系統{Xα,παβ,Λ}的逆極限,|Λ|=λ,假設每個映射πα∶X→Xα是開的且到上的,X是λ-仿緊,每個Xα是正規可數仿緊的,則X是正規可數仿緊的。
