直流约瑟夫森电流的表达式，这是书面的Andreev反射的概率幅度的手段，通过详细的平衡的反射幅度。 所得到的公式在物理上是合理的，因为电流正比于类电子准粒子向类空穴准粒子散射的振幅与反向散射的振幅之差。 该公式将有助于研究超导介观系统。
An expression of the dc Josephson current, which is written by means of the probability amplitude of the Andreev reflections, is obtained by detailed balance of the reflection amplitudes. The formula obtained is physically reasonable in that the current is proportional to the difference between the amplitude of the scattering of an electron-like quasiparticle into a hole-like quasiparticle and that of the reverse scattering. This formula will be useful in studying superconducting mesoscopic systems.
