在以前的一篇论文中，我们讨论了由于壳层的量子涨落和由此产生的视界而引起的壳层坍缩对霍金辐射的修正。为了计算量子修正，我们使用了几个近似。在本文中，我们考虑了在前一篇文章中被忽略的影响。我们发现了重要的校正，包括高频辐射的非热贡献和频率相关的时间尺度，在该时间尺度上频率热辐射的发射切断。这样的尺度在经典壳的极限下趋于无穷大。一个人几乎从一开始就有非热辐射，这一事实对信息悖论具有重要意义。特别是非热力的量比我们之前估计的要大得多。对蒸发时间的初步估计表明，蒸发速度比通常的霍金分析要快。
In a previous paper we discussed corrections to Hawking radiation from a collapsing shell due to quantum fluctuations of the shell and the resulting horizon. For the computation of the quantum corrections we used several approximations. In this paper we take into account effects that were neglected in the previous one. We find important corrections including non-thermal contributions to the radiation at high frequencies and a frequency dependent time scale at which the emission of thermal radiation of frequency cuts off. Such scale tends to infinity in the limit of a classical shell. The fact that one has almost from the outset non-thermal radiation has significant implications for the information paradox. In particular the amount of non-thermality is considerably larger than what we had estimated before. A naive estimate of the evaporation time suggests a faster evaporation than in the usual Hawking analysis.
