我们考虑有限一维系统中电子的动力学，该系统受均匀电场影响（或环中的电子；受时间相关磁通量感应的电动势影响）。在由于局部电势而存在弹性散射的情况下，驱动源不会在稳态下向系统提供能量。评估存在非弹性散射时的耗散。即使在弱局域化极限下，系统的欧姆电阻也主要取决于非弹性率。
We consider the dynamics of an electron in a finite one-dimensional system, subject to a uniform electric field (or an electron in a ring; subject to an emf induced by a time-dependent magnetic flux). In the presence of elastic scattering due to localized potentials the driving source does not supply energy to the system in the steady state. The dissipation in the presence of inelastic scattering is evaluated. The Ohmic resistance of the system depends crucially on the inelastic rate even in the weak-localization limit.
