我们展示了在引力坍缩中，大时间的霍金辐射如何精确地与球体上的标度极限有关，在球体上，恒星半径与Schwarzschild半径相交(只要忽略辐射对度规的反向反应)。对于自由量子场，它可以被精确地计算出来，其结果与霍金的预言一致。对于现实的量子场论来说，基于一般原理的评估似乎是不可能的。出射辐射取决于场论模型。
We show how in gravitational collapse the Hawking radiation at large times is precisely related to a scaling limit on the sphere where the star radius crosses the Schwarzschild radius (as long as the back reaction of the radiation on the metric is neglected). For a free quantum field it can be exactly evaluated and the result agrees with Hawking's prediction. For a realistic quantum field theory no evaluation based on general principles seems possible. The outcoming radiation depends on the field theoretical model.
