δ－双仿紧空间的乘积

Product of δ-Biparacompact Spaces

对于任意δ－双仿紧空间族｛（Ｘ＿λ，τ＿λ，σ＿λ）｝λ∈г（г是任意指标集），是ｘ的任意τ开复盖，构造了Ｘ的τＶσ开发盖Ω＝｛Ｂ￣ｔ｝τ∈Ｔ，并证明Ω是的局部有限τＶσ开加细，从而证明了其积空间（Ｘ，τ，σ）也是δ－双仿紧空间．

Let {(X_λ,τ_λ,σ_λ)}λ∈г(гis an arbitrary index set)be a family of δ--biparacompactspaces,and be X's arbitrary,τ open covering,we constructed X's:opencovering Ω={B￣t}t∈T,and proved that Ω is,to loeally finite open refinement,therebyproved its product space(X,τ,σ)is still a δ-biparacompact spaces.
