江苏省对口单招综合理论考试中,无论是机电专业、电子电工专业还是计算机专业,对戴维宁定理这一知识点,考纲要求都是:熟练运用戴维宁定理来分析、计算复杂直流电路。而在近几年的考试中,也频频出现了戴维宁定理的大题。对于常规的求解一条支路电流或电压的考题,学生都不觉得是困难的事,但是一旦题型变化一下,学生往往无所适从,思路也混乱起来。本文笔者结合自己的教学实践,从各种题型的变化入手,总结了各种变化题型的求解方法,希望给教者和学者以启迪。
Jiangsu Province, the single-strokes comprehensive theoretical examination, whether it is mechanical and electrical major, electronic or electrical engineering or computer professional, Thevenin theorem of knowledge, the test requirements are: proficiency in the Thevenin theorem to analyze and calculate the complex DC circuit. In recent years, the exam has frequently appeared in Thevenin’s theorem. Students do not find it difficult to routinely solve a branch current or voltage test, but once the type of question changes, students tend to be confused and confused. In this paper, the author combines his own teaching practice, starting with the changes of various kinds of questions, summarizes the methods of solving various kinds of questions, hoping to enlighten teachers and scholars.
