By considering the absorption of a charged particle, the thermodynamic laws and weak cosmic censorship conjecture are investigated for Reissner–Nordstöm–anti–de Sitter black holes with prefect fluid dark matter. We find that the first law of thermodynamics and the second law of thermodynamics are still valid in AdS spacetime with dark matter. In particular, we test the validity of weak cosmic censorship conjecture by studying how the minimum value of the function that determines the position of the horizon changes. As a result, it shows that there are always horizons that make the weak cosmic censorship conjecture hold, and the extreme black holes can evolve into non-extreme black holes in dark matter background.

通过考虑带电粒子的吸收，研究了具有完美流体暗物质的 Reissner-Nordstöm-anti-de Sitter 黑洞的热力学定律和弱宇宙审查猜想。我们发现热力学第一定律和热力学第二定律在有暗物质的 AdS 时空中仍然有效。特别是，我们通过研究决定视界位置的函数的最小值如何变化来检验弱宇宙审查猜想的有效性。结果表明，弱宇宙审查猜想总是存在视界，极端黑洞可以在暗物质背景下演化为非极端黑洞。
