我们制定并证明了一个精确的关系，表示的时刻的两点电导的开放无序电子系统在相应的封闭系统的某些密度因子。作为该关系的应用，我们证明了临界状态下Chalker-Coddington模型的典型两点电导像共形场论中的两点函数一样变换。
We formulate and prove an exact relation which expresses the moments of the two-point conductance for an open disordered electron system in terms of certain density correlators of the corresponding closed system. As an application of the relation, we demonstrate that the typical two-point conductance for the Chalker-Coddington model at criticality transforms like a two-point function in conformal field theory.
