介绍了舰船电力系统用的1MJ螺管型高温超导储能磁体的设计优化步骤，给出了用Bi-2223超导带进行1MJ磁体线圈的设计和优化结果，分析了高温超导体的各向异性对磁体临界电流的影响，讨论了储能容量一定的多螺管磁体系统在漏磁、储能密度和所需超导线材方面的变化。

This paper outlines a systematic procedure for the design of a solenoidal coil and presents the optimum design of 1 MJ HTS magnet which is designed with Bi-2223 tape. At last the authors analyse the main magnetic component which influences the maximum critical current and discuss energy density, stray field and superconductors needed in multiple solenoid magnet with different elements.
