摘要
指出了用内向Eddington坐标研究蒸发型Vaidya黑洞热效应可能出现的困难.通过引入一个坐标变换,新的坐标系下对应的困难消失.在新的坐标系下分别用Damour-Ruffini方法和辐射反作用法重新计算了Vaidya黑洞的温度,并讨论了熵,所得结果是合理的.
Drawbacks of the ingoing Eddington coordinates in describing the quantum thermal effects of the evaporating Vaidya black hole are presented. By introducing a new coordinate transformation proposed previously, the difficulties in calculating black hole temperature and black hole entropy vanish. In this new coordinate system, black holes＇ temperature is calculated again in Damour-Ruffini method and back action method, respectively. The entropy of the black hole is also investigated. The results are reasonable.
