经典黑洞和事件视界是高度非局域的对象，是根据未来类光无穷远的因果过去来定义的。在数学相对论、量子相对论和数值相对论中，常常使用黑洞的替代准局域特征描述。这些包括表观视界、基林视界、陷俘视界、孤立视界、动力学视界以及缓慢演化视界。所有这些都与外向类光膨胀为零的二维面密切相关。本文回顾了黑洞的传统定义，并概述了一些关于替代视界的近期研究工作。

Classical black holes and event horizons are highly nonlocal objects, defined in relation to the causal past of future null infinity. Alternative, quasilocal characterizations of black holes are often used in mathematical, quantum, and numerical relativity. These include apparent, Killing, trapping, isolated, dynamical, and slowly evolving horizons. All of these are closely associated with two-surfaces of zero outward null expansion. This paper reviews the traditional definition of black holes and provides an overview of some of the more recent work on alternative horizons.PACS Nos.: 04.20.Cv, 04.70.s, 04.70.Bw
