考虑到最近的实验和理论研究结果的介观正常金属超导结以及超导弱连接的超导邻近效应的当前理解进行了审查。尽管人们对这一现象已经了解了40年，但仍然知之甚少。目前的见解是导致非平衡准经典理论的理论发展的结果，在亚微米尺度上获得接近结构的实验，并将其与80年代在无序和弹道系统中开发的量子输运知识相结合。
The current understanding of the superconducting proximity effect is reviewed taking into account recent experimental and theoretical results obtained for mesoscopic normal metal-superconductor junctions as well as superconducting weak links. Although known for 40 years the phenomenon remained poorly understood. Current insights are the result of theoretical developments leading to the nonequilibrium quasiclassical theory, getting experimental access to proximity structures on a submicron scale as well as by combining it with the knowledge developed in the 80s on quantum transport in disordered and ballistic systems.
