摘　　要：首先介绍了非Abel输运理论基础 ,然后在经典非Abel输运理论的基础上引入并评述了平均场动力学 .作为应用 ,研究了有限化学势下冷密夸克物质系统的色动力学并计算出了色导率 .最后比较了有限温度和有限化学势下的结果 。We first review the non-Abelian transport theory and its mean field dynamics. The theory is then applied for studying the color electric dynamics of cold and dense quark matter at large chemical potential, and color conductivity with non-perturbation effect is obtained. Finally, we compare the results at large chemical potential with that at high temperature, and discuss possible applications in the field of astrophysics.
