摘要
在Tortoise坐标系中,利用brick-wall模型研究了电磁场对Vaidya-Bonner-deSitter黑洞熵的量子修正.当黑洞事件视界不随超前时间变化时,结果与Reissner-Nordstrom-deSitter黑洞的量子熵完全相同.
In the tortoise coordinates,the quantum corrections to the entropy of the Vaidya-Bonner-de Sitter black hole due to electromagnetic field are investigated by using the brick-wall model. When the event horizon of the black hole does not depend upon the advanced-time, the result coincide with that of the Reissner-Nordstrm-de Sitter black hole.
