求翻译：A little-known and highly economical characterization of the real interval [0,1], essentially due to Freyd, states that the interval is homeomorphic to two copies of itself glued end to end, and, in a precise sense, is universal as such. Other familiar spaces have similar universal properties; for example, the topologi是什么意思？ 待解决

真正区间 0，[1]，本质上是由于 Freyd 不为人知、 高度经济表征，各国间隔是自身的两个副本，同胚粘附端到端、 精确的意义上，如是普遍。其他熟悉的空间具有相似的通用属性 ；例如，单形拓扑 Δn 可定义为普遍承认重心细分的空间的家庭。我们开发这种普遍的刻画的一般的理论。
