Maxwell方程组是“非对称的”：电场有一个负电极子和一个正电极子，带着不同的电荷； 但磁场却没有。

Maxwell's equations are "asymmetrical": electricity has an electron monopole and a proton monopole, each with opposite charge, but magnetism does not.

利用麦克斯韦方程组和场的轴对称性，分别对含不稳定电荷源和不稳定电流源的轴对称非静态空间电磁场进行了研究。

By using the Maxwells equations and axial symmetry, the axial symmetric unstable electromagnetic field with unstable charge source and unstable current source is studied.
