摘要
我们研究引力坍缩中形成的四维球对称黑洞的蒸发。我们通过半经典爱因斯坦方程，分析了一个无质量量子标量场与标量曲率共形耦合时的反作用。我们表明，蒸发与动力学视界处的入射负能流有关，并且只要满足合适的平均能量条件，该能流就是由黑洞视界外的量子物质迹反常所诱导的。为说明起见，我们在由 Vaidya 时空描述的零辐射星的情形下，计算了入射负能流及相应的蒸发速率。

21 pages, 2 figure. Changed abstract and introduction, modified section 3, added figure about the smearing function. Added some references and made minor corrections. Made slightly modifications of the ANEC and of the smearing function presented in the statement of Theorem 4.1 (p.10). Added corrections to the final part of the proof of Theorem 4.1
