假设真空能量动量张量不是特别大，我们考虑具有球对称性的4D蒸发黑洞，并评估类时视视界与进入视视界后塌缩物质表面之间的适当距离Delta L。我们证明，当黑洞蒸发到其初始质量的 1/n 时，只要 n 满足，Delta L 永远不会大于 O(n(3)/(2)l(p))
Assuming that the vacuum energy-momentum tensor is not exceptionally large, we consider 4D evaporating black holes with spherical symmetry and evaluate the proper distance Delta L between the timelike apparent horizon and the surface of the collapsing matter after it has entered the apparent horizon. We show that Delta L can never be larger than O(n(3)/(2)l(p)) when the black hole has evaporated to 1/n of its initial mass, as long as n
