| 摘 要： | 许多医用理疗设备都需要使用通电空心线圈产生磁场,磁场产生方式有利用线圈外部的磁场和线圈空心内部的磁场两种,而这两种方式都将由多个线圈实现。通电线圈排布的合理设计能够提高磁场的均匀性,这将对疗效产生重要的影响,因此分别研究了上述两种磁场的特性。研究结果表明:根据线圈的直径大小和线圈相对距离的配合可以产生最优均匀磁场。

| Abstract: | Magnetic field generated by axis symmetric coils is widely applied in many medical physiotherapy apparatus where the magnetic field on the surface of the coils or inside the coils is employed,and appropriate arrangement of the coils helps improve the homogeneity of the magnetic field,which affects the therapy results.Conclusions are drawn that optimal homogenous magnetic fields can be devised when the diameters of the coils and the distances between them fit each other on the analysis of the reasonability o... |
