摘　　要：本文采用MgB2/Fe/Cu单芯复合线材制作了一个小型实验线圈,并以此为基础,对用MgB2线、带材制成的线圈在承载较大电流情况下的交流损耗特性进行了仿真和实验研究,结果表明,为使MgB2/Fe/Cu复合线材适于电力应用,应设法大幅降低基体损耗.A small test coil using mono-filarnent MgB2/Fe/Cu wire was made. Based on this coil, the ac loss properties under a high ac current were investigated both numerically and experimentally. The results show that for power applications, the ac losses caused by the sheath materials in the MgB2 wire must be sharply depressed.
