In this work, we study the Hawking temperature of the global monopole spacetime (non-spherical symmetrical black hole) based on the topological method proposed by Robson, Villari, and Biancalana (RVB). By connecting the Hawking temperature with the topological properties of black holes, the Hawking temperature of the global monopole spacetime can be obtained by the RVB method. We also discuss the Hawking temperature in massive gravity, and find that the effect of the mass term cannot be ignored in the calculation of the Hawking temperature; the corrected Hawking temperature in massive gravity can be derived by adding an integral constant, which can be determined by the standard definition.
在这项工作中，我们基于罗布森（Robson）、维拉里（Villari）和比安卡拉纳（Biancalana）（RVB）提出的拓扑方法，研究了整体单极时空（非球对称黑洞）的霍金温度。通过将霍金温度与黑洞的拓扑性质联系起来，整体单极时空的霍金温度可以用RVB方法得到。我们还讨论了大质量引力中的霍金温度，发现质量项在霍金温度的计算中不能被忽略；大质量引力中修正后的霍金温度可以通过添加一个积分常数来推导，该常数可由标准定义确定。
