In this study, we examine the laws of thermodynamics and the weak cosmic censorship conjecture in the normal and extended phase spaces of Born-Infeld-anti-de Sitter black holes by considering a charged particle absorption. In the normal phase space, the first and second laws of thermodynamics as well as the weak cosmic censorship are still valid. However, in the extended phase space, the second law of thermodynamics is violated for double-horizon black holes and part of single-horizon black holes. The first law of thermodynamics and the weak cosmic censorship conjecture are still valid for all types of black holes. In addition, we found that the shift of the metric function, which determines the locations of the horizons, takes the same form at the minimum point in both the normal and extended phase spaces, indicating that the weak cosmic censorship conjecture is independent of the thermodynamic phase space.

在这项研究中，我们通过考虑带电粒子吸收来检验 Born-Infeld-anti-de Sitter 黑洞的正常相空间和扩展相空间中的热力学定律和弱宇宙审查猜想。在正常相空间中，热力学第一定律和第二定律以及弱宇宙审查仍然有效。然而，在扩展相空间中，双视界黑洞和部分单视界黑洞违反了热力学第二定律。热力学第一定律和弱宇宙审查猜想仍然适用于所有类型的黑洞。此外，我们发现确定视界位置的度量函数的偏移在正常相空间和扩展相空间的最小点处采用相同的形式，
