By using the Maxwell's equations and axial symmetry, a method on calculating non-static axial symmetry fields with unstable charge source is given. 摘要利用麦克斯韦方程组和场的轴对称性，给出了由对称轴的非静态电场计算含不稳定电荷源的轴对称非静态空间电磁场的一种方法。
More research is focused on the cylindrical HTS magnetic levitation system rather than the system with translational symmetry. 相比轴对称式系统的研究，平移对称式高温超导磁悬浮系统的研究结果相对较少，动态研究少于准静态研究。
