In the branch of mathematics known as topology, the specialization (or canonical) preorder is a natural preorder on the set of the points of a topological space. For most spaces that are considered in practice, namely for all those that satisfy the T0 separation axiom, this preorder is even a partial order (called the specialization order). On the other hand, for T1 spaces the order becomes trivial and is of little interest.

- 在数学分支拓扑学中，特殊化（或规范）预序是在拓扑空间上的自然预序。对在实践中考虑的大多数空间，特别是满足T0 分离公理的那些空间，这个预序甚至是偏序（叫做特殊化序）。在另一方面，对于T1空间这个次序成为平凡的而没有价值。 特殊化序经常在计算机科学应用中考虑，这里的T0空间出现在指称语义中。特殊化序对于识别在偏序集合上合适的拓扑空间是重要的，这在序理论所要做的。 (zh)

For most spaces that are considered in practice, namely for all those that satisfy the T0 separation axiom, this preorder is even a partial order (called the specialization order). On the other hand, for T1 spaces the order becomes trivial and is of little interest. The specialization order is often considered in applications in computer science, where T0 spaces occur in denotational semantics. The specialization order is also important for identifying suitable topologies on partially ordered sets, as is done in order theory. (en)
