The superconducting magnetically levitated vehicle is simplified as an infinite - long system whose cross section is considered . a model based on the method proposed by l . prigozhin is built to describe the force the superconductor may experience when moving above the guideway 在理论计算方面，首先对现有高温超导磁悬浮实验车系统进行了简化，将实际的三维系统简化为无限长直均匀系统，因此仅需分析该系统任一二维截面即可。
