对拟连续domain引入了关于基的性质MF,证明了对拟连续domain P,任两个Scott紧上集的交是Scott紧当且仅当P关于某一(任一)基具有性质MF.
The concept of property MF relative to a base of quasicontinuous domain is introduced. It is proved that for a quasicontinuous domain P, the intersection of any two Scott upper compact sets is still Scott compact if and only if P satisfies property MF with respect to any (some) base.
