中文摘要：

主要讨论了南半层空间上的闭映射性质，证明了k半层空间的闭映像若是不含有闭子空间同胚于Sω1（Sω）的岛空间，则该闭映射是边缘s映射（边缘紧映射）最后给出例子表明弱层空间未必是层空间，否定回答了关于层空间的一个问题．

英文摘要：

The closed mapping properties of k semistratifiable spaces are discussed. It is shown that every closed mapping on k semistratifiable spaces is a boundary s mapping （resp. boundary compact mapping） if the image is a k space and contains no closed copy of Sωl （resp. Sω）. Finally, an example is given to show that a weak stratifiable space is not necessarily a stratifiable space. Thus, a question about stratifiable spaces is negatively answered.
