摘　　要：通过4种不同的方法,分别计算了动态Vaidya黑洞的温度.方法1和方法2分别利用Parikh的量子隧穿方法和Hamilton-Jacobi方法计算作用量虚部,进而求得黑洞的温度.方法3引入广义的乌龟坐标变换,利用改进的Damour-Ruffini方法,得到了黑洞的温度.方法4则由黑洞热力学第一定律直接计算黑洞温度.计算结果表明,4种方法所得温度是协调一致的.Four methods were used to calculate the temperature of a Vaidya black hole. Parikh＇s quantum tunneling method and ttamilton-Jocobi method were first used to compute the imaginary part of the action, to obtain the black hole temperature. Generalized tortoise coordinate transformation and Domour-Ruffini method were introduced to obtain the black hole temperature also. Finally, the first law of black hole thermodynamics was utilized to obtain black hole temperature directly.
