1) hereditarily submetacompact
遗传次亚紧
1.
The author mainly obtained the following two theorems: (1)Let X=σ{x α:α∈A},if every finite subproduct of X is strong submetacompact, then X is strong submetacompact; (2) Let X=σ{x α:α∈A}, if every finite subproduct of X is heredifarily submetacompact and X normal, then X is hereditarily submetacompact.
主要获得如下两个定理：（１）设Ｘ＝σ｛Ｘα：α∈Ａ｝，如果Ｘ的每个有限子积是强次亚紧的，则Ｘ是强次亚紧的；（２）设Ｘ＝σ｛Ｘα：α∈Ａ｝，如果Ｘ的每个有限子积是遗传次亚紧的且Ｘ正规，则Ｘ是遗传次亚紧的。

In this paper,we show the result:A space X is a hereditarily submetacompact space if and only if every scattered partition of X has a θ-sequence of open expansions.
本文获得如下结果：（＊）Ｘ是遗传次亚紧空间当且仅当Ｘ的每个散射分解有个开的θ－膨胀序列。
2) hereditarily normal weakly submetacompact
遗传正规弱次亚紧
3) Hereditarily σ metacompact
遗传σ-亚紧
4) hereditarily σ-bounded metacompactness
遗传σ-有界亚紧
5) Hereditarily submetaexpandable
遗传次亚可膨胀
6) hereditarily |∑|-paracompact
遗传|∑|-仿紧

This paper mainly proves: (1) Let X =Πσ∈hereditarily |∑|-paracompactXσ be hereditarily |∑|-paracompact|hereditarily |∑|-paracompact| hereditarily |∑|-paracompact, X is hereditarily |∑|-paracompactnormal weak θ -refutable if Πσ∈hereditarily |∑|-paracompactXσ is hereditarily |∑|-paracompactnormal weak θ -refinable for every F ∈ [hereditarily |∑|-paracompact]<ω.
主要证明:(1)如果X=Πσ∈∑Xσ是遗传|∑|-仿紧空间,则X是遗传正规弱(?)-可加空间当且仅当(?)F∈|∑|<ω,Πσ∈FXσ是遗传正规弱(?)-可加空间。
