受Robinson等人的工作的启发,我们推广协变反常理论和广义乌龟坐标变换研究了Vaidya黑洞事件视界处的Hawking辐射,结果表明用协变反常理论计算,可以得到正确的Hawking辐射流和黑洞温度.
Motivated by the work of Robinson et al, we have researched Hawking radiation from the event horizon of Vaidya black hole via covariant anomalies theory and general tortoise coordinate transformation, and the result shows that the Hawking temperature can be correctly determined by covariant anomalies at the horizon.
