| 摘 要： | 描写电磁场性质的通量和环量概念，因无熟悉的事物可借鉴和类比，故“理解不能到位”的焦虑感常常困扰着学生。实践证明，在“电磁学”课程的绪论中，勿惜时间，将两概念大胆地进行前瞻与俯视，教学效果会有极大改观。

| Abstract: | Having no familiar things for reference or analogy to describe the flux and ring amount concepts of electric magnteic field nature,students often have trouble understanding it.Practice has proved that in the introduction of electro magnetics course,teachers may boldly measure and overlook at the prospect of the two concepts,not caring much about time,then great changes will happen in the teaching result. |
