最近，我们展示了如何通过固定时空中存在的锥形亏角来建立ADS空间中单个(带电)加速黑洞的热力学第一定律。在这里，我们展示了如何推广这一结果，建立了具有不同锥形亏损的黑洞的热力学公式。我们推导出了变化张力缺陷的新势能：加速黑洞和静态黑洞的热力学长度。我们讨论了黑洞末端弦的张力可能发生变化的可能的物理过程，并绘制了加速黑洞的热力学相空间，并探索了它们的临界现象。
Recently we have shown [1] how to formulate a thermodynamic first law for a single (charged) accelerated black hole in AdS space by fixing the conical deficit angles present in the spacetime. Here we show how to generalise this result, formulating thermodynamics for black holes with varying conical deficits. We derive a new potential for the varying tension defects: the thermodynamic length, both for accelerating and static black holes. We discuss possible physical processes in which the tension of a string ending on a black hole might vary, and also map out the thermodynamic phase space of accelerating black holes and explore their critical phenomena.
