摘要
如果令乌龟坐标下的二维时空线元在视界附近共形于明氏时空,可以容易地定出Nerr-Newman黑洞视界的位置和温度.如果进而讨论Klein-Gordon方程,则能得到热辐射谱,以及电荷与转动附加在热谱上的特征.这种方法可推广应用于具有视界的一般稳态时空.
The location and the temperature of event horizon of Kerr- Newman space-time can be easily determined by supposing that line element represented with Tortoise coordinate is conformal to 2-dimensional Minkowski space-time near the event horizon.With Klein-Gordon equation,one can obtain Planck spectrum of thermal radiation coming from the event horizon, which shows electric charge effect and rotation effect of the black hole. This method can be generalized to a universal stationary space-time where there exists an event horizon.
