摘要
证明自然界只有两种电荷及其分析、归纳及推理的逻辑过程历来是教学难点、重点，大多数教师仅是演示被丝绸（毛皮）摩擦过的玻璃棒（橡胶棒）互相排斥，以及两者之间互相吸引，就得出了自然界只有两种电荷及电荷间相互作用的规律．本文将给出详实的证明过程．
It is the difficult and important points of teaching：to prove that there are only two kinds of charges in nature and the logic process of its analysis, induction and reason. Most of the teachers only demonstrate that the stick） rubbed by silk（skin）is mutual exclusion or mutual attraction, it is concluded that only two kinds and charges interaction law. This paper will show a detailed proof process glass rod （rub ber of electric charges
