摘　　要：主要获得了两个拓扑空间的Tychonoff乘积是σ仿紧空间的3个定理In this paper,we mainly obtained following three theorems on σ paracompact spaces.If X is a σ paracompact P space,Y is a paracompact or σ expandable strong  space,then X×Y is a σ paracompact space,or if {X p:p∈N} are countable σ paracompact strong  spaces,then ∏p∈NX p is a σ paracompact space.

关 键 词：σ-仿紧空间 P-空间 TYCHONOFF乘积 拓扑空间
