标题： Hawking radiation and thermodynamics of dynamical black holes in phantom dominated universe

摘要： 在存在黑洞的情况下，暗能量主导的宇宙的热力学性质在方程状态参数 $w(a)$变化的普遍情况下被研究。 我们表明，在虚幻划分交叉处所有热力学量都是正常的，特别是暗流体的温度和熵始终是正定的。 我们还研究了黑洞对虚幻流体的吸积过程以及热力学广义第二定律有效性的条件。 作为结果，我们得到一个严格负的化学势和一个方程状态参数 $w<-5/3.$ 显示英文摘要

摘要： The thermodynamic properties of dark energy-dominated universe in the presence of a black hole are investigated in the general case of a varying equation-of-state-parameter $w(a)$. We show that all the thermodynamics quantities are regular at the phantom divide crossing, and particularly the temperature and the entropy of the dark fluid are always positive definite. We also study the accretion process of a phantom fluid by black holes and the conditions required for the validity of the generalized second law of thermodynamics. As a results we obtain a strictly negative chemical potential and an equation-of-state parameter $w<-5/3.$
