摘要
利用任意加速带电动态黑洞视界面附近子系统的熵,导出黑洞的瞬时辐出度,得到了任一时刻黑洞沿某一方向的瞬时辐出度总是正比于在该方向上黑洞视界温度的四次方的结论.导出的广义Stefan-Boltzmann系数是一个与黑洞视界的变化率、黑洞视界面附近的时空度规及黑洞的吸收与辐射系数有关的动比例系数.
Using entropy of subsystem of near event horizon of the arbitrarily accelerating non-stationary black hole with electric charges, the instantaneous radiant existence is calculated out , and it is gained that the instantaneous radiant exitance of blank hole at a direction at any time is always proportionate to quarto power of temperature of the event horizon of black hole on this direction. It is found that the factor of generalized Stefan-Boltzmann is a dynamic proportional coefficient related to the rate of a change of event horizon the structure of space-time near event horizon and the radiation tion coefficient of black hole.
