摘要
本文研究了包括圆环线圈与螺管线圈在内的轴对称线圈以及圆弧段电流单元所产生的静磁场中矢量磁位与磁通密度的计算，着重讨论了计算中完全椭圆积分与奇点的处理。在此基础上，对０．１５Ｔｅｓｌａ磁共振成像电阻式磁体进行了分析。
In this paper,the magnetostatic field computation of the axisymmetric coils,which includes the current-carrying loop and solenoid coil,has been described.Besides,the computation of current-carrying circular are filament has also been discussed.In particular,the calculation and treatment of the singularity are studied in detail.As applications,the resistant magnet for 0.15Tesla magnetic resonance imaging(MRI) has been analysed,and gradient coils for permanent MRI designed.
