摘　　要：本文引入有限温度和有限化学势的AdS/RN度规的非共形场的软墙模型,计算喷注淬火参数随化学势的变化关系,并与共形场情况下的喷注淬火参数结果比较。结果发现:在一定温度下,喷注淬火参数随着化学势的增加而减小,在相同温度和相同化学势的情况下,非共形场情况下的喷注淬火参数比共形场情况下的要大。本研究为深入了解相对论重离子碰撞喷注淬火特征提供了理论依据。The soft wall model at finite temperature and chemical potential has been introduced in the paper to calculate the jet quenching parameter.The comparisons of the dependences of jet quenching parameter on chemical potential in the non-conformal field with the conformal are given in this paper.Through this work,we can understand some important characteristics of jet quenching in the relativistic heavy ion collisions.It is shown that the jet quenching parameter decrease with the increase of chemical potential.Meanwhile,the jet quenching parameter in the non-conformal field is larger than in the conformal field with the same temperature and the same chemical potential.
