In this paper, we investigate the thermodynamics and weak cosmic censorship conjecture in a RN-AdS black hole with the cloud of strings and quintessence by the scattering of a scalar field. The variations of the thermodynamic variables are calculated in the normal and extended phase spaces. In the normal phase space, where the cosmological constant is considered as a constant, the first and second laws of thermodynamics are satisfied. In the extended phase space, where the cosmological constant and the parameters related to the cloud of strings and quintessence are treated as variables, the first law of thermodynamics is still satisfied and the second law of thermodynamics is indefinite. Moreover, we find that the weak cosmic censorship conjecture is valid for the extremal and near-extremal black holes in both phase spaces.

在本文中，我们通过标量场的散射研究了RN-AdS黑洞中的热力学和弱宇宙检查猜想，该黑洞带有弦云和精髓。在正相和扩展相空间中计算热力学变量的变化。在将宇宙常数视为常数的正相空间中，满足了热力学的第一定律和第二定律。在扩展相空间中，将宇宙常数和与弦云和典型度相关的参数视为变量，热力学的第一定律仍然得到满足，热力学的第二定律是不确定的。此外，我们发现弱的宇宙检查猜想对于两个相空间中的极端和接近极端的黑洞都是有效的。
