电路是电学的基础知识,电路作图是学好电学必须掌握的基本技能。本文所说的电路作图,是指根据电路图连接实物图,根据实物图画出电路图两种情况。电路作图既是电学的重点,也是难点,初学者往往不易掌握。笔者通过潜心研究,探索出一套行之有效的方法——我把它叫做数码排序作图法,比较成功地解决了电路作图这个难题。经过本人及同行多年的教学实践证实,此法简便易学,几乎所有学生都能看懂学会。 Circuits are the basic knowledge of electricity, and circuit drawing is a basic skill that must be mastered by electricians. The circuit drawing described in this article refers to the two cases in which the physical map is connected according to the circuit diagram and the circuit diagram is based on the physical diagram. The circuit drawing is not only the focus but also the difficulty of electricity. It is often difficult for beginners to master it. Through intensive research, the author explored a set of effective methods - I called it digital mapping, and successfully solved the circuit drawing problem. After years of teaching practice by myself and my colleagues, it is proved that this method is easy to learn and almost all students can read and understand the society.
