论文摘要
我们研究了通过非线性电动力学（NED）抗DE保姆（ADS）黑洞在扩展的相空间中磁性充电的热力学和相变。宇宙常数被视为热力学压力，而黑洞质量则被视为化学焓。黑洞的地平线热力学与Van der Waals液态气体系统相比。我们定义了与NED参数和磁电荷的参数相结合的数量。结果表明，热力学的第一定律和广义的Smarr关系保持。关键指数与范德华系统中的相同。由于黑洞的热力学行为，研究了NED-ADS黑洞的Thomson绝热膨胀。讨论了焦耳 - thomson系数，反转和静脉曲线。获得了最小反转温度和相应的事件范围半径。
We study thermodynamics and phase transitions of magnetically charged by nonlinear electrodynamics (NED) Anti-de Sitter (AdS) black holes in an extended phase space. The cosmological constant is treated as a thermodynamic pressure whereas the black hole mass is considered such as the chemical enthalpy. The horizon thermodynamics of black holes shows an analogy with the Van der Waals liquid-gas system. We define a quantities which are conjugated to the parameter of NED and a magnetic charge. It is shown that the first law of thermodynamics and the generalized Smarr relation hold. The critical exponents are the same as in the Van der Waals system. The Joule--Thomson adiabatic expansion of NED-AdS black holes is investigated because of thermodynamic behavior of black holes. The Joule--Thomson coefficient, the inversion and isenthalpic curves are discussed. The minimum of inversion temperature and the corresponding event horizon radius are obtained.
