摘　　要：在拖曳坐标系中,从反常的角度讨论了Kerr-de Sitter黑洞的霍金辐射.为了描述可观测的物理现象,我们忽略事件视界处的入射模和宇宙视界处的出射模来建立有效理论.结果表明,用来恢复事件视界和宇宙视界处的规范流和能动张量流精确地等于霍金辐射流.We have studied Hawking radiation from the Kerr-de Sitter black hole in draggling coordinate frame from anomalies. To describe the observable physics, we have ignored the classically irrelevant ingoing modes at the event horizon （EH） and the classically irrelevant outgoing modes at the cosmological horizon （CH） to formulate the effective theory. The result shows that the gauge current and energy momentum tensor fluxes required to restore the gauge covariance and general coordinate invariance at the EH and the CH are precisely equal to those of Hawking radiation.
