| 摘 要： | 采用一种新的乌龟坐标变换，我们在Damour-Ruffini．Sannan理论的框架下研究了做变加速直线运动和任意加速运动的Kinnersley黑洞中Weyl中微子的Hawking辐射现象．结果发现，与采用通常乌龟坐标变换所得到的结果比较，Hawking辐射的谱分布仍然呈黑体谱形式但辐射温度明显不同；此外，对任意加速运动的Kinnersley黑洞而言，其Hawking辐射温度除受加速度大小的变化影响外，还与加速度在角度方向上的变化率有关．

| Abstract: | Under different tortoise coordinate transformations, we investigate the Hawking radiations of Weyl neutrinos in rectilinearly-accelerating and arbitrarily-accelerating Kinnersley black holes. Our discussion is based on the Damour- Ruffini-Sannan theory and find that, all the derived Hawking radiation spectra show still the blackbody ones, but the Hawking temperatures are significantly different. Additionally, it is shown that, for arbitrarily-accelerating Kinnersley black holes, the Hawking radiation temperatures depend on the varying of acceleration in both the numerical sizes and angles. |
