宇宙学表观视界的霍金辐射和热力学

摘要

Using Damour-ruffini method, two kinds of dynamical tortoise coordinate transformations havebeen applied to investigate Hawking radiation from the apparent horizon in the Friedmann-robertson-walker (FRW) cosmology. Our results show that Hawking temperature can be obtained on the apparent horizon in the FRW cosmology.%利用Damour-ruffini方法，分别应用两种动态乌龟坐标变换研究了Friedmann—robertson-walker（FRW）宇宙学表观视界的霍金辐射．结果表明可以在FRW宇宙学的表观视界上得到霍金温度并建立对应的热力学第一定律．
