论文摘要
结果表明，在黑洞中添加诸如电荷或角动量之类的头发会减少熵发射的量。这激发了我们研究在四个维度时空中热系统的局部熵发射率（$ \ dot {s} $）的最大熵速率（$ \ dot {s} $）的最大限制（上限），并认为此上限为$ \ dot是$ \ dot {s} \ simeq k_ {b} {b} { G}} $。同样，通过考虑rènyi熵，可以表明贝肯斯坦 - 黑尾熵导致熵发射速率的最大极限。我们还建议在黑洞的表面重力上有一个上限，称为普朗克表面重力。最后，我们获得了最大的熵发射速率，普朗克表面重力和黑洞的普朗克温度之间的关系。
It is shown that adding hair like electric charge or angular momentum to the black hole decreases the amount of entropy emission. This motivates us to study the emission rate of entropy from black holes and conjecture a maximum limit (upper bound) on the rate of local entropy emission ($\dot{S}$) for thermal systems in four dimensional space time and argue that this upper bound is $\dot{S}\simeq k_{B} \sqrt{\frac{c^5}{\hbar G}}$. Also by considering Rènyi entropy, it is shown that Bekenstein-Hawking entropy leads to a maximum limit for the rate of entropy emission. We also suggest an upper bound on the surface gravity of the black holes which is called Planck surface gravity. Finally we obtain a relation between maximum rate of entropy emission, Planck surface gravity and Planck temperature of black holes.
