研究了在广义相对论和非线性电磁场作用下的磁荷规则黑洞（MCRBH）的热力学性质，并与四维和二维的Reissner-Norstrom（RN）黑洞进行了降维比较.我们发现，在两个维度中，对于固定电荷Q，规则黑洞和RN黑洞之间没有热力学差异。这意味着在坐标原点处的奇异性或正则性条件不影响黑洞的热力学。此外，我们还结合Jackiw-Teitelboim理论描述了MCRBH的近视界AdS（2）热力学。我们还通过AdS（2）/CFT 1对应将近视界熵确定为统计熵。
We investigate thermodynamics for a magnetically charged regular black hole (MCRBH), which comes from the action of general relativity and nonlinear electromagnetics, comparing with the Reissner-Norstrom (RN) black hole in both four and two dimensions after dimensional reduction. We find that there is no thermodynamic difference between the regular and RN black holes for a fixed charge Q in both dimensions. This means that the condition for either singularity or regularity at the origin of coordinate does not affect the thermodynamics of black hole. Furthermore, we describe the near-horizon AdS(2) thermodynamics of the MCRBH with the connection of the Jackiw-Teitelboim theory. We also identify the near-horizon entropy as the statistical entropy by using the AdS(2)/CFT1 correspondence.
