By throwing a test charged particle into a Reissner-Nordstrom (RN) black hole, we test the validity of the first and second laws of thermodynamics and the weak cosmic censorship conjecture (WCCC) with two types of boundary conditions: the asymptotically anti-de Sitter (AdS) space and a Dirichlet cavity wall placed in an asymptotically flat space. For the RN-AdS black hole, the second law of thermodynamics is satisfied, and the WCCC is violated for both extremal and near-extremal black holes. For the RN black hole in a cavity, the entropy can either increase or decrease depending on the change in the charge, and the WCCC is satisfied/violated for the extremal/near-extremal black hole. Our results indicate that there may be a connection between the black hole thermodynamics and the boundary condition imposed on the black hole.

通过将测试带电粒子抛入 Reissner-Nordstrom (RN) 黑洞，我们在两种边界条件下检验了热力学第一和第二定律以及弱宇宙审查猜想 (WCCC) 的有效性：渐近反德Sitter (AdS) 空间和放置在渐近平坦空间中的 Dirichlet 空腔壁。RN-AdS黑洞满足热力学第二定律，极值黑洞和近极值黑洞都违反了WCCC。对于空腔中的 RN 黑洞，熵可以根据电荷的变化而增加或减少，对于极值/近极值黑洞，WCCC 是满足/违反的。我们的结果表明，黑洞热力学和施加在黑洞上的边界条件之间可能存在联系。
