摘　　要：运用Damour-Ruffini方法研究黑洞的Hawking辐射.在保持时空中总能量守恒的条件下,考虑辐射粒子对时空的反作用后,得到了黑洞视界处粒子出射率与Bekenstein-Hawking熵有关,辐射谱不再是严格的纯热谱.所得结果与他人的工作一致,且满足量子力学的幺正性原理.Taking into consideration the radiation particle reaction with the total energy of spacetime conservation, Hawking radiation from black hole is re-investigated using the Damour-Ruffini method. It is found that the tunneling probability relates to Bekenstein-Hawking entropy, and the radiation spectrum is not exactly thermal. The result is consistent with the works of other researchers, and satisfies the unitary theory of quantum mechanics.
