任意加速运动黑洞的温度和熵

The temperature and entropy of arbitrarily accelerating non-static black hole

采用Tortoise坐标变换,约化视界面附近Klein-Gorden方程,得到黑洞的Hawking温度.用薄膜brick-wall模型,通过选择适当的截断因子和薄层厚度,在视界面附近薄层上的熵就是黑洞的熵,结果表明黑洞熵与视界面积成正比.

This paper presents that using the Tortoise coordinate transformation and the Klein-Gorden field equation near the event horizon, the Hawking temperature of black hole is obtained. Using thin film brick-wall model to calculate the entropy of black hole, we get the entropy near the event horizon is actually the entropy of black hole by choosing the cut-off factor and the thin film＇ s thickness properly. The results show that the entropy of the black hole is in direct proportion to the area of the event horizon.
