论文摘要
我们研究了一个碰撞的彭罗斯工艺的功能，并从极端的雷德斯特斯特斯特罗姆黑洞中提取了未结合的能量。在黑洞外部恒定的径向坐标处，该过程需要无限的时间坐标。对于黑洞作为发电厂，观察者远离黑洞的过程的力量很有用。我们将功率定义为从极端的Reissner-Nordström黑洞中的能量增益除以在坐标时间内的过程间隔。我们估计功率的上限在接近马的限制中，而该过程的效率可能是任意限制的。因此，我们得出的结论是，在极端的Reissner-nordström时空中，碰撞的Penrose过程中的效率和权力之间没有权衡的关系。
We investigate the power of a collisional Penrose process with an unbound energy extraction from an extreme Reissner-Nordström black hole. This process takes infinite time in a time coordinate at a constant radial coordinate outside of the black hole. For black holes as a power plant, the power of the process for an observer far away from the black hole can be useful. We define the power as energy gain from the extreme Reissner-Nordström black hole divided by the time interval of the process in a coordinate time; we estimate the upper bound of the power in a near-horizon limit, while the efficiency of the process can be arbitrary large in that limit. Thus, we conclude that there is no trade-off relation between the efficiency and power in the collisional Penrose process in extreme Reissner-Nordström spacetime.
