摘　　要：利用黑洞视界面附近的熵密度,研究了黑洞的热辐射规律,得到了黑洞的热辐射满足广义Stefan-Boltzmann定律的结论.对极端Reissner-Nordstrm黑洞,其辐射能通量和辐射功率为零,表明广义Stefan-Boltzmann定律将导致黑洞遗迹.当截断距离、薄膜厚度取定后,距Reissner-Nordstrm黑洞遥远的观测者接收到的辐射能通量与辐射粒子的径向的平均泻流速率成正比,与观测者到黑洞之间的距离的平方成反比.By the entropy density near the event horizon,the thermal radiation of the black hole was studied.The generalized Stefan-Boltzmann law was obtained.For an extreme Reissner-Nordstrm black hole,radiation energy flux and radiation power were all equal to zero.Generalized Stefan-Boltzmann law would lead to a black hole remnant.When the thin film thickness and the cut-off distance were both fixed for the Reissner-Nordstrm black hole,the radiation energy flux received by observer far away from the Reissner-Nordstrm black hole was proportional to the average radial effusion velocity of the radiation particles,and inversely proportional to the square of the distance between the observer and the black hole.
