摘　　要：散度和旋度是研究电磁现象的重要工具,由于其定义抽象、计算复杂,一直是电磁理论教学过程中的重点和难点。本文就实际教学过程中,学生容易发生混淆或难以理解的旋度的计算、散度和旋度的联系、亥姆霍兹定理等知识点进行了讨论,帮助学生很好地掌握这一内容。Divergence and curl are important tools in research on electromagnetic phenomenon. For abstract define and complex calculation, divergence and curl are key points and difficulties in the teaching of Electromagnetism. This paper presents discussion, aiming at the difficuhis such as the calculous of curl, the relationship bteween di- vergence and curl, knowledge points of Helmhohz＇s theorem. All these works plays an active role for the under- standing of divergence and curl.

关 键 词：电磁场 散度 旋度
