我们研究了（2 + 1）维巴纳多斯 - 泰特尔鲍姆 - 赞内利黑洞和克尔 - 德西特时空情况下的热力学第一定律。特别地，我们关注积分质量公式。研究发现，通过将宇宙学常数视为一个可变的状态参数，渐近平直时空下黑洞热力学第一定律的微分和积分质量公式都可以直接推广到反德西特和德西特背景下的旋转黑洞。应当指出，这些公式在任何维度下都成立。
We investigate the first law of thermodynamics in the case of the (2+1)-dimensional Banados–Teitelboim–Zanelli black holes and Kerr–de Sitter spacetimes. In particular, we focus on the integral mass formulas. It is found that by assuming the cosmological constant as a variable state parameter, both the differential and integral mass formulas of the first law of black hole thermodynamics in the asymptotic flat spacetimes can be directly extended to those of rotating black holes in anti-de Sitter and de Sitter backgrounds. It should be pointed that these formulae come into existence in any dimensions.
