摘要
通过黑洞热力学第一定律,由黑洞的熵来计算黑洞的温度.由此方法算出的史瓦西黑洞和克尔-纽曼黑洞的温度与以前的结果相符,Vaidya黑洞的温度与引入新的乌龟坐标变换后算得的结果一致.
Utilizing the first law of thermodynamics for the black hole, the temperature of the black hole is calculated by its entropy. The temperatures of Schwarzchild and Kerr-Newman black holes computed by this method are identical with the result computed by the definition of black hole＇s surface gravity, while the temperature of Vaidya black hole accords with the outcome calculated by reducing the Klein--Gordon equation near the event horizon to standard form with a new tortoise coordinate transformation.
