国内出版的电路教材中,部分非器件符号的含义和应用比较混乱。这不仅给学生的自学带来困扰,也对老师讲授教学内容带来了一定的麻烦。依据多年教学实践,通过对物理量符号、接地符号和无源符号约定的应用等几个问题的分析,得出这部分非器件符号应该统一标准并在教材中增补明确说明。文章对提高电气电子专业课的教学质量也有一定的帮助作用。

The meaning and application of some non-device symbols in electric circuit textbooks published in China are confused. This not only brings trouble to students＇ self-study, but also brings some trouble to teachers. According to the teaching practice for many years, through the analysis of the application of physical quantity symbol, grounding symbol and passive symbol agreement, it is concluded that this part of non-device symbol should be unified standard and be added to the textbook clearly.
