利用Banerjee，Majhi在JHEP 06：095 2008中提出的方法，将黑洞的Hawking辐射看作是量子隧穿，在半经典近似下用Hamilton-Jacobi方法处理，从而给出了FRW宇宙中所有的高阶量子修正.在我们的分析中，Kodama矢量代替Killing矢量来定义粒子的能量起着关键的作用。我们分别在Friedmann-Robertson-步行者类坐标系和非常类似于Painlevé坐标系下给出了我们的分析。结果表明，该公式化方法可以推广到对动力系统的Hawking辐射进行全面分析。
An analysis of Hawking radiation about apparent horizon in a FRW universe is performed by using the method developed in the paper (Banerjee, Majhi in JHEP 06:095 2008), in which the Hawking radiation of a black hole is treated as the quantum tunneling by Hamilton-Jacobi method beyond semiclassical approximation and then all the higher order quantum corrections can be given out. In our analysis, the Kodama vector instead of the Killing vector to define the energy of the particle plays a key role. We present our analysis under the Friedmann-Robertson-Walker like coordinate system and the much-like to Painlevé coordinate system respectively. The result show that the formulized procedure can be extended to fully analyse the Hawking radiation of a dynamical system.
