在Bogoliubov-deGennes（tMG）方程的基础上，研究了考虑自旋与轨道耦合效应下S波超导体／绝缘层／声波超导体结的直流Josephson效应．研究表明：夕波超导体结的直流Josephson电流与温度、结的相位差的关系强烈地依赖于P波超导体的配对势形式，结界面的自旋与轨道耦合散射对s／I／p波的结直流Josephson电流有抑制作用也有增强作用．
Using Bogoliubov-de Gennes （BdG） equations,we study the dc Josephson effect by taking into account the spin-orbit coupling on tunneling effect in s/I/p junction. It is found that the phase and the temperature dependence of the de Josephson current in the p-wave superconductor junction strongly depends on kinds of pairings. The spin-orbit coupling on tunneling scattering not only suppresses but also enhances the dc currents in s/I/p junction.
