我们通过要求辐射消除视界上可能存在的反常来计算五维带电旋转黑环的量子辐射。结果表明，其温度、能量通量和角动量通量与霍金辐射完全一致。本文所考虑的黑环包含迈尔斯 - 佩里黑洞作为一种极限情况，并且文献中得到的该黑洞的量子辐射在极限情况下得以恢复。这些结果支持了霍金辐射可被视为视界上反常消除器的观点，并表明它普遍适用于近期发现的高维黑洞。
We calculate the quantum radiation from the 5-dimensional charged rotating black rings by demanding the radiation eliminate the possible anomalies on the horizons. It is shown that the temperature, energy flux, and angular-momentum flux exactly coincide with those of the Hawking radiation. The black rings considered in this paper contain the Myers-Perry black hole as a limit, and the quantum radiation for this black hole, obtained in the literature, is recovered in the limit. The results support the picture that the Hawking radiation can be regarded as the anomaly eliminator on horizons and suggest its general applicability to the higher-dimensional black holes discovered recently.
