粤教版普通高中物理选修3-1第一章第八节“静电与新技术”介绍了静电除尘实验的基本原理,但既没有介绍实验仪器的具体制作过程和实验操作步骤,又没有介绍用什么方法收集实验所需要的大量烟雾。为此,笔者对教材中的实验仪器进行了巧妙改进,改进后的器材不光实验效果明显,而且收集烟雾也非常轻松。
Guangdong version of the general high school physics elective 3-1 chapter eighth section “electrostatic and new technology ” introduced the basic principles of electrostatic dust experiment, but neither the specific experimental equipment experimental procedures and experimental steps, and no Describe in what ways to collect a large amount of smoke required for the experiment. To this end, the author of the teaching materials in the experimental apparatus has been cleverly improved, the improved equipment not only the experimental effect is obvious, but also to collect smoke is also very easy.
