主　　题：closed maps sequence-covering maps weak bases sn-networks cs-networks k-semistratifiable spaces. 

摘      要：In this paper,we mainly discuss the images of certain spaces under closed sequencecovering *** is showed that the property with a locally countable weak base is preserved by closed sequence-covering *** the following question is discussed:Are the closed sequence-covering images of spaces with a point-countable sn-network sn-first countable?
