我们推广的标度理论的本地化各向异性系统，使用图解分析和推导相应的场论的有效行动。我们发现，在弱耦合（金属）固定点附近的各向异性的影响可以完全吸收到各向异性扩散系数。两个二维和三维系统的影响进行了讨论，并获得了良好的协议与实验结果，由主教，Dynes，林，徐。
We generalize the scaling theory of localization to anisotropic systems, using both a diagrammatic analysis and deriving the effective action for the corresponding field theory. We find that the effects of anisotropy near the weak coupling (metallic) fixed point can be completely absorbed into an anisotropic diffusion coefficient. Implications for both two-and three-dimensional systems are discussed, and excellent agreement is obtained with experimental results on the former by Bishop, Dynes, Lin, and Tsui.
