| 摘 要： | 静电屏蔽是“电磁场与电磁波”课程静电场教学中的一个重要知识点。本文基于Ansoft工程电磁场有限元分析软件，给出金属罩接地与不接地情况下，对空间电场分布的影响。分析结果表明，闭合的金属罩可屏蔽内部空间以防电磁干扰，接地的金属罩能实现全屏蔽。对场的空间描绘可增加学生对场的感性认识，提高教学效果。

| Abstract: | Static-shielding is an important knowledge point in the course of Electromagnetic Field and Electromagnetic Wave, An ordinary sphere shielding is an example based on software of Ansoft engineering electromagnetic field finite element analysis, electric field lines will be changed in the event of metal cavum grounding or not. At the same time electric field lines will be changed along a certain line. Results show all closed cavum being grounded is needed in order to achieve all shielding. The teaching and measures can increase the students＂ sensibility cognition on the electromagnetic field theory. |
