apparent t horizon视地平线
apparent dip of horizon地平视俯角
It is shown that in the accelerating universe the generalized second law of thermodynamics holds only in the case where the enveloping surface is the apparent horizon,but not in the case of the event horizon.
结果表明:在加速膨胀宇宙中,只有在表观视界包络的体系中,广义热力学第二定理才成立,而在事件视界包络的体系中,广义热力学第二定理不成立。
