静电复印是利用静电的一个典型的实例.静电复印机大家都不陌生,但是庞大的复印机内部到底有着怎样的结构,复印的基本原理和过程到底是怎样的呢?高中物理“静电的利用与防范”这一节内容给我们介绍了静电复印的基本原理.但是笔者在教学过程中发现静电复印的原理对绝大多数同学来说都是一个难点,因为看不到复印机的内部结构,所以很难理解复印的过程,最后唯一能记住的就是静电复印利用的是正负电荷之间的吸引作用.为此,笔者用易拉罐、黏贴纸、粉笔灰等设计了一套模拟实验,模 Electrostatic photocopying is a typical example of the use of static electricity. Electrostatic copiers are familiar, but what kind of structure is there in a large photocopier? What are the basic principles and processes of copying? "This section introduces us to the basic principles of xerography, but the author found in the teaching of electrostatic copying principle for most students are a difficult, because they can not see the internal structure of the copier, so very Difficult to understand the process of copying, the only thing that can be remembered finally is the attraction between the positive and negative charges by the use of electrostatic copying.Therefore, the author designed a set of simulation experiments with cans, sticky paper, chalk and so on
