摘　　要：该文采用新的广义乌龟坐标变换后,在事件视界附近直接求解Klein-Gordon方程,得到以(t,r)坐标描述的轴对称Kerr黑洞的视界位置、辐射温度.计算结果表明,考虑蒸发后Kerr黑洞的视界面是一个随时间变化的椭球面,Hawking辐射温度不仅随时间变化,而且与方位角有关.进一步分析表明Hawking辐射温度是时间坐标尺度下的补偿效应.After using the new generalized tortoise coordinate transformation,authors obtainthe location of horizon and radiation temperature of axis symmetric Kerr black hole with coor-dinate (t,r) as variable,through directly solving K-G equation near the event horison. The re-sult of calculating indicate that on the condition that the effect of evaporation is considered,thehorison surface of Kerr black hole is a elliptic spherical.surface which changes with time,Hawking radiation temperature is not only relative to time.but also the azimuth. Further the re-sults indicate that Hawking radiation temperature can be regarded as a compensate effect underthe time-scale transformation.
