导出了双势垒约瑟夫森结中弹道电子输运的一般解。我们证明了超流与单势垒透明度成正比的位相相干输运机制的存在，以及随着层间厚度的增加这种相干被破坏的方式。确定了在任意电压下的准粒子电流。
The general solution for ballistic electronic transport through double-barrier Josephson junctions is derived. We show the existence of a regime of phase-coherent transport in which the supercurrent is proportional to the single-barrier transparency and the way in which this coherence is destroyed for increasing interlayer thickness. The quasiparticle de current at arbitrary voltage is determined.
