THE JOSEPHSON TUNNELLING OF SUPERCONDUCTOR-GRAIN-SUPERCONDUCTOR JUNCTION (S-G-S)
超导—阵列—超导(S-G-S)结Josephson隧道特性

Under the mean-field approximation, the Josephson tunnelling of superconductor-grain-superconductor junction is analyzed in this paper by using the path-integral formulation. For the cases with coupling and without coupling between the grains, the temperature deperdence of Josephson critical current Ic and the phase dependence of Josephson current I are obtained.
