Abstract
The author proved the following results: Let X= lim ←{X σ,π σ ρ,Σ} and every π σ be open and onto mapping,(1) if X is |Σ| paracompact and every X σ is normal and weakly refinable, then X is normal and weakly refinable; (2) if X is hereditarily |Σ| paracompact and every X σ is hereditarily normal and hereditarily weakly refinable, then X is hereditarily normal and hereditarily weakly refinable.
