In this paper, the Joule–Thomson expansion of the higher dimensional nonlinearly anti-de Sitter (AdS) black hole with power Maxwell invariant source is investigated. The results show the Joule–Thomson coefficient has a zero point and a divergent point, which coincide with the inversion temperature T _i and the zero point of the Hawking temperature, respectively. The inversion temperature increases monotonously with inversion pressure. For the high-pressure region, the inversion temperature decreases with the dimensionality D and the nonlinearity parameter s, whereas it increases with the charge Q. However, T _i for the low-pressure region increase with D and s, while it decreases with Q. The ratio η _BH between the minimum inversion temperature and the critical temperature does not depend on Q, it recovers the higher dimensional Reissner–Nrdstrom AdS black hole case when s = 1. However, for s > 1, it becomes smaller and smaller as D increases and approaches a constant when D → ∞ . Finally, we found that an increase of mass M and s, or reducing the charge Q and D can enhance the isenthalpic curve, and the effect of s on the isenthalpic curve is much greater than other parameters.

在本文中，研究了具有功率麦克斯韦不变源的高维非线性反德西特（AdS）黑洞的焦耳-汤姆森展开。结果表明，焦耳-汤姆逊系数有一个零点和一个发散点，分别与逆温T _i和霍金温度的零点重合。转化温度随转化压力单调增加。对于高压区，反转温度随着维数D和非线性参数s 的增加而降低，而随着电荷Q 的增加而增加。然而，低压区的T _i随D和 s，而它随着Q减小。最小反转温度与临界温度之间的比值η _BH不依赖于Q，它在s = 1时恢复了更高维的 Reissner-Nrdstrom AdS 黑洞情况。 然而，对于s > 1，它随着D变得越来越小当D → ∞时增加并接近一个常数。最后，我们发现增加质量M和s，或减少电荷Q和D可以增强等焓曲线，并且s的影响 在等焓曲线上远大于其他参数。
