分离公理
在拓扑学及相关的数学领域里，通常对于所讨论的拓扑空间加有各种各样的限制条件，分离公理即是指之中的某些限制条件。这些分离公理有时候被叫做吉洪诺夫分离公理，得名于安德烈·尼古拉耶维奇·吉洪诺夫。部分分离公理以字母T开头，是由德文单词“Trennung”而来，意义是分离。
分离公理之所以称为公理，是因为以前定义拓扑空间时，有些人会将其也做为公理来定义，而得出较现在意思狭义的拓扑空间。但在拓扑空间的公理化完成后，那些都成了「各种」的拓扑空间。然而，「分离公理」这一词就这样固定了下来。

Separation axiom 分离公理
In topology and related fields of mathematics, there are several restrictions that one often makes on the kinds of topological spaces that one wishes to consider. Some of these restrictions are given by the separation axioms. These are sometimes called Tychonoff separation axioms, after Andrey Tychonoff.
