摘　　要：面场强的计算是电磁学中一类常见问题。然而目前的文献在研究此类问题时都忽略了一个问题,即没有解释位于场点所在处的面元的场强为什么是0。本文指出了这一问题并给出了解决方案,所得结论对面场强计算的教学具有较大的参考价值。It is a kind of common question in electromagnetism that the electric field of the surface charge and the magnetic field of the surface current are calculated.But a problem is neglected by the present literatures which research this kind of question,and the problem is that no reasons are given for the facts that the field of the charge or the current which is positioned in the surface infinitesimal is zero.In this paper,the problem is pointed out,and the solutions are given.The conclusions have much reference value for the teaching of the calculations of the electric field of the surface charge and the magnetic field of the surface current.
