摘　　要：当外加磁场时,超导体/半导体/超导体结的临界电流受外加磁场的影响.超导结的临界电流与磁场的曲线非常类似于单色光在单狭缝衍射的夫琅和费图样.在未考虑外加磁场的超导体/半导体/超导体结的临界电流的基础上,进一步对外加磁场的情形进行了研究.The critical currents of superconductor, semiconductor and superconductive junction are influenced by the external magnetic field when an external magnetic field exists. The curve of current changing with the magnetic field has strong analogy to the graph of Fraunhofer single-slit diffraction. On the bases of the critical currents of superconductor, semiconductor and superconductive junction without external magnetic field, the critical currents with the external magnetic field are investigated.
