我们考虑具有守恒全局电荷的强耦合规范理论等离子体，允许双重引力描述。我们研究了这些电荷存在化学势时规范理论等离子体的剪切粘度。利用规范理论与弦理论的对应关系，证明了剪切黏度与熵密度之比在大的霍夫特耦合下是普适的。
We consider strongly coupled gauge theory plasma with conserved global charges that allow for a dual gravitational description. We study the shear viscosity of the gauge theory plasma in the presence of chemical potentials for these charges. Using gauge theory/string theory correspondence we prove that at large 't Hooft coupling the ratio of the shear viscosity to the entropy density is universal.
