摘　　要：在Robinson和Wilczek工作的基础上,研究了Schwarzschild-de Sitter时空的引力反常.为了避免对时空整体对称性的破坏,必须消除引力反常,进而得到了黑洞两视界面(黑洞视界和宇宙视界)处都有霍金辐射.The method of Robinson and Wilczek was extended to Schwarzschild-de Sitter space-time, with two event horizons, one black hole horizon and one cosmological horizon. Gravitiational anomalies were studied and Hawking radiation from both horizons were obtained by cancelling gravitiational anomaly in order to avoid a complete breakdown of space-time symmetry.

关 键 词：引力反常 霍金辐射 边界条件 整体对称性
