摘　　要：利用动态Dilaton-Maxwell黑洞视界面附近的熵密度,导出黑洞的瞬时辐射流量,得到了任一时刻黑洞沿某一方向的瞬时辐射流量总是正比于在该方向上黑洞事件视界温度的四次方的结论.导出的广义Stefan-Boltzmann系数不再是一个恒量,而是一个与黑洞视界面附近的时空度规、黑洞视界的变化率及黑洞的吸收与辐射系数有关的动比例系数.揭示了黑洞周围的引力场与其热辐射之间存在着必然的内在联系.Using entropy density near event horizon of the non-stationary Dilaton-Maxwell black hole,the instantaneous emission flux is calculated,and we come to a conclusion that the instantaneous emission flux of blank hole in any direction at any time is always proportionate to the quartic power of temperature of the event horizon of black hole in that direction.It is found that the coefficient of generalized Stefan-Boltzmann is no longer a constant,but a dynamic proportional coefficient related to the rate of change of event horizon,the structure of space-time near event horizon and the radiation absorption coefficient of black hole.It shows that an inner relation between the gravitational field around black hole and its thermal radiation must exist.
