【摘要】 交界面条件是"电磁场"教材的重要内容。本文针对静磁场交界面条件应用教学过程中发现的具有非光滑边界同轴问题,深入探讨交界面上磁介质产生的磁化面电流分布,提出交界面条件只适用于交界面光滑的场合。非光滑交界面问题需要全面检验交界面条件,只有满足麦克斯韦方程组和边界条件时才能利用矢量场唯一性定理说明解是正确的。更多还原

【Abstract】 Boundary conditions are significant content of Electromagnetic Field.The problem of coaxial cable is found when boundary conditions are applied to solve magneto-static field with unsmooth boundary.Therefore,further investigation is made to find the magnetized current distribution in magnetic media.Premise of smooth boundary is proposed to properly use boundary conditions.All boundary conditions must be checked in solving problems with unsmooth boundary.Only when the solution satisfies the Maxwell equations and the boundary conditions,could it be validated by the theorem of uniqueness of vector field.更多还原
