摘要： 设X=lim｛Xα,παβ,Λ｝,λ=|Λ|,如果X是λ仿紧的且每个Xα是σcf可膨胀的(σcsf可膨胀的),则X是σcf可膨胀的(σcsf可膨胀的)。

Abstract: ｛Xα,παβ,Λ｝,λ=|Λ|. If X is　λparacompact and each　Xα　is　σcfexpandable(σcsfexpandable), then X is　σcfexpandable(σcsfexpandable).

Key words: σcfexpandable, inverse limits, hereditarily σcfexpandable spaces
