摘要
本文在两个层次上(首先,在一般小直圆柱状盒子面或小长方形回路上,其次,在任意形状小闭合面或小闭合回路上),摒弃不必要的假设,充分利用各个相应矢量在微元范围内为一恒矢量这一特点,从而,合乎逻辑地推得电磁场边界条件。
This paper intents to explain this problem in two steps:the first is re- lated to a surface of a small cylinder or a small rectegular path,the second related to a small closed surface of any shape or a small closed path of any shape.Excluding any unnecessary supposition and making full use of thecharacteristic that every corresponding vector at a micro—range is a con- stantvector,this paper logically deduces boundary condition for electromagnetic fields.
