| 中文摘要: |
| 通过引入局部下半连续集值映射的概念, 建立了遗传覆盖性质与多种选择之间的一些重要联系, 说明了选择构造本身与原象空间的分离性无关. |
| 英文摘要: |
| In this paper, by introducing the concept of locally lower semi-continuous set-valued mappings,
the author obtains some important relations between hereditary covering properties and various kinds of selections.
Moreover, it is shown that the construction of selections does not have relations with separation properties of preimage spaces. |
