摘　　要：在求解麦克斯韦方程组时,采用的定解条件为圆柱界面,似稳状态。获得似稳条件下导体圆柱面内的涡电流分布的严格数学解,并获得低频和高频情况下涡电流,涡旋电磁场的近似解,进而求出了趋肤效应的穿透深度δ。The strict solution of the eddy current distribution inside a conductor cylindrical boundary surface for quasi-steady-state is obtained by derivation of Maxwell′s equations; meanwhile, the approximate solution of the eddy current and electromagnetic field in the condition of the low-frequency or the high-frequency are obtained. Furthermore, the penetration depth of the skin effect is achieved.
