论文摘要
考虑到扩展相位空间中抗DE保姆（ADS）背景的负宇宙常数为正热力压力，我们通过研究$ p- \ p- \ p- \ upsilon $ crigicalon $ tircal-upsilon $和冷却 - 热相位过渡，研究了常规海沃德 - ads（HADS）黑洞（HADS）黑洞（BH）的热力学行为。我们比较了HADS BH和BARDEEN-ADS（BADS）BH之间两个热力学过程的差异。发现BH的相位转变BH倾向于更多是Van der Waals（VDW）相变。对于冷热相变，我们发现在相同的压力和磁电荷下，HADS BH的反转曲线总是高于BAD BH。我们还比较了最小的存在质量，零温度残留物和临界磁电荷。结果表明，海沃德BH的内部地平线和外界更容易合并，并且奇异性更容易暴露。
Considering the negative cosmological constant of an anti-de Sitter (AdS) background as a positive thermodynamic pressure in the extended phase space, we study the thermodynamic behaviors of the regular Hayward-AdS (HAdS) black hole (BH) by investigating $P-\upsilon$ critical and cooling-heating phase transition. We compare the difference of two thermodynamic processes between the HAdS BH and the Bardeen-AdS (BAdS) BH. It is found that the phase transition of the BAdS BH tends to be more the van der Waals (vdW) phase transition. For the cooling-heating phase transition, we find the inversion curves of the HAdS BH are always higher than the BAdS BH under the same pressure and magnetic charge. We also compare the smallest existence mass, the zero-temperature remnant, and the critical magnetic charge. The results suggest that the inner horizon and the outer horizon of the Hayward BH are easier to merge, and the singularity is easier to expose.
