| 摘 要： | 运用两种不同的乌龟坐标变换,我们研究了Vaidya de Sitter黑洞的标量粒子的隧穿情况.最终得到了黑洞视界附近辐射粒子的隧穿率以及视界处的霍金温度,通过比较会发现其结果不会因坐标变化的不同而发生改变.

| Abstract: | Using the general and the corrected tortoise coordination transformation,we investigate the tunneling of scalar particles from Vaidya de Sitter black hole.Then the tunneling probability near the horizon and Hawking temperature at this horizon are obtained.It is showed that final results are not related with the choice of tortoise coordination transformation. |
