摘　　要：讨论了在Barriola-Vilenkin黑洞情形下,由于整体单极的出现对时空所产生的影响,用协变反常的观点研究了来自整体单极Barriola-Vilenkin黑洞视界的霍金辐射.结果表明:为了保持广义协变性,本文中所得到的能动张量流和由黑体辐射谱推导出的能动张量流是完全一致的.The influence of global monopole in the Barriola-Vilenkin black hole case is first taken into account, and then Hawking radiation from the horizon of global monopole Barriola-Vilenkin black hole is studied via eovariant anomalous viewpoint. The result we get in this context shows that the energy-momentum tensor flux, which is required to restore general coordinate covariance, is exactly equal to that of blackbody radiation spectrum.
