| 摘 要： | 在演示避雷针的工作时，有时会有异常放电现象发生，它不是在避雷针的尖端部分而是在其球形部分出现。因为避雷针的工作不是建立在尖端放电的基础上的，故这类演示实验应从物理教科书中删除掉。

| Abstract: | In demonstrating the operation of lightning rod, extraordinary discharge happens sometimes,which appears not at the tip but at the round Part of the lightning rod, and a negative charge area Occurring around the tip is responsible for such discharge. Since the operation of lightning rod is not based on point discharge, such kind of demonstration should be deleted from physics textboods. |
