带有电荷、磁荷的一类任意加速黑洞的瞬时辐射能通量

利用带有电荷、磁荷的一类任意加速黑洞视界面附近标量场的熵密度,研究黑洞的热辐射规律,导出了黑洞的瞬时辐射能通量,得到了黑洞的热辐射总是满足广义Stefan-Boltzmann定律的结论.导出的广义Stefan-Boltzmann系数不是常数,而是一个与黑洞参量(质量、所带的电荷与磁荷、加速度的大小、视界的变化率)有关的动比例系数.对于不同的动态黑洞,由于黑洞周围的引力场和电磁场不同,导出的广义Stefan-Boltzmann系数也不同.

Instantaneous radiation energy flux of the scalar field in arbitrarily accelerating black hole with electric charge and magnetic charge

Using entropy density of scalar field near event horizon in an arbitrarily accelerating black hole with electric charge and magnetic charge,we study the law for the thermal radiation of black hole and the instantaneous radiation energy flux is obtained. It is found that the thermal radiation of a black hole always satisfies the generalized Stefan-Boltzmann's law. The proportional coefficient of generalized Stefan-Boltzmann is no longer a constant,and it becomes a dynamic coefficient that is related to the p...
