摘　　要：利用延拓Damour-Ruffini方法,研究Schwarzschild-de Sitter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和黑洞事件视界与宇宙视界的相互关联后,得到黑洞辐射谱.此辐射不再是严格的纯热谱,与黑洞事件视界和宇宙视界对应Bekenstein-Hawking熵变有关,发现其结果仍然符合幺正性原理.We extend the classical Damour-Ruffini method and discuss Hawking radiation in Schwarzschild-de Sitter black hole.Under the condition that the total energy of spacetime is conservative,considering the effect of radiation particle on the spacetime and the relevance between the black hole event horizon and cosmological horizon,we obtain the black hole radiation spectrum.The radiation spectrum is no longer a pure thermal spectrum.It is related to Bekenstein-Hawking entropy change corresponding to the black hole event horizon and cosmological horizon. The result is consistent with an underlying unitary theory.
