磁通量穿过的非超导小环中的持续电流是亚微米系统中新量子效应的表现。我们目前的理论结果为一个通道和多通道系统的电流振幅的依赖通道的数量和几何形状，温度和无序度。非弹性散射仅考虑单通道回路。我们还讨论了该效应的可观测性。
Persistent currents in small nonsuperconducting rings threaded by a magnetic flux are a manifestation of novel quantum effects in submicron systems. We present theoretical results for one-channel and multichannel systems concerning the dependence of the current amplitude on the number of channels and geometry, temperature, and degree of disorder. Inelastic scattering is considered for one-channel loops only. We also discuss the observability of the effect.
