摘　　要：从空间中的开集族的开加细与散射分解的开膨胀之间的关系,给出了空间的散射分解具有某种性质的开膨胀的充要条件。The relation between the expansion of a space＇s scattered partition and the open refinement of open sets in it is studied. The sufficient conditions for a space having the property is given that its every scattered partition has a open expansion of a given property.
