摘　　要：Bi2 2 2 3/Ag带材的强各向异性决定了其临界电流对垂直于带材表面的磁场非常敏感 ,这是该带材在高温超导磁体等强电应用方面的不利因素 .我们从减小磁体最大径向场BRmax对磁体运行电流的影响、充分利用超导材料的原则出发 ,讨论了高温超导磁体的设计方法 .在小型Bi2 2 2 3/Ag实验磁体的设计中 ,根据对径向磁场的计算、分析 。The high sensitivity of the critical current of the Bi2223/Ag tapes to the magnet field component perpendicular to the wide face of the tapes, which is caused by the high anisotropy of this kind of materials is a disadvantage for its electric power applications. The design of HTS magnet has been discussed in the paper taken into account of the effect of the maximum radical magnetic field of the magnet on its operating current. It leads to the result of raising the magnet working current and reducing HTS material. In the design of the miniature Bi2223/Ag experimental magnet, we decided the magnet working points according to the calculated results of magnetic field distribution in the winding and I-c of the Bi2223/Ag tapes.
