摘　　要：文章回顾了"导致Hawking效应的普遍坐标变换"一文中产生Unruh-Hawking效应的条件,对这些条件的作用进行了梳理.基于同样的方法,作者找到了能导致可延拓分叉Killing视界的充分条件并做出了证明.新的条件原则上也可以把非时轴正交的情况包括进来.由于可延拓分叉Killing视界普遍具有非零的表面引力,因此,也可以说这些新条件是导致Unruh-Hawking效应的充分条件.最后以极端RN黑洞为例,讨论了极端Killing视界的情况.This article reviews conditions and analyzes the role of these conditions leading to the Uneffect proposed in the paper titled “ Universal coordinate transformation leading to Hawking effect”. Based onthe same method , we find the sufficient conditions of leading to the continuable Bifurcate Killing horizon , and a demonstration is given. New conditions proposed in this paper , in principle , can also include the situation of non orthogonal time axis and space axis. Due to surface gravity being non-zero on the continuable Bifurcate Kill-ing horizon , these conditions are also the sufficient conditions of leading to the Unruh-Hawkingas an example , we discuss the situation on the extreme Killing horizon of the RN black holes.
