通过建立具有局部可数弱基的空间与局部可分度量空间之间的关系,证明了具有局部可数弱基的空间是g-可度量空间,1-序列复盖商ss-映射保持具有局部可数弱基的空间.

It is verified that a regular space with a locally countable weak-base is -metrizable. The relationships are established between spaces with a locally countable weak-base and locally separable metric spaces by means of compact-covering maps, 1-sequence-covering maps, π -maps and ss-maps. It is also verified that 1-sequence-covering, quotient, -maps preserve spaces with a locally countable weak base.
