摘　　要：在共形反常修正背景下,利用两点关联函数我们研究了修正参数对等离子体热化行为的影响,根据Ad S/CFT对偶,这等同于通过类空测地线探测共形反常修正背景下物质壳的引力坍塌过程.结果表明,随着共形反常修正系数增大,等离子体从非平衡态到平衡态的热化时间更长.我们还得到了热化曲线的拟合函数,基于这一函数,进一步得到了热化速度和热化加速度.根据热化速度曲线,我们发现热化过程可以分成加速相和减速相,相变点随着共形反常修正系数增大而增大.With the two point correlation function, we investigate the effect of the correction parameters on the thermalization of Plasma in the background corrected by conformal anomaly. In terms of the AdS/CFT correspondence, this equals to probe the collapse of a shell of dust by the like-space geodesic in the background corrected by conformal anomaly. The result shows that as the parameter corrected by conformal anomaly increases, the thermalization time for the plasma evolving from the non-equilibrium state to the equilibrium state is longer. We also get the fitted function of the thermalization curve, and based on the function, we further obtain the thermalization velocity and thermalization acceleration. With the thermalization velocity curve, we find the thermalization process can be divided into a acceleration phase and a deceleration phase, the phase transition point raises as the parameter corrected by conformal anomaly increases.
