抓住“相量”进行正弦电路的稳态分析

Analysis of Sine Circuits in Stable State on the Basis of "Vector" (On Teaching of the Circuit Analysis in Colleges)

针对高等学校《电路分析》中“正弦稳态电路的分析” 这一教学重点、难点,在教学中正确引入“相量” 的概念,简化正弦稳态电路分析过程中繁杂的数学运算;通过归纳、对比、总结,达到由浅入深、循序渐进的教学目的。

The article is about how to apply the concept of 'vector' correctly to the teaching and to simplify the complicated calculations in analyzing sine circuits in stable state in accordance with the analysis of sine circuits in stable state, the key point and the special difficulty taught in colleges. It is aimed at going from the easier to the more complicated and step by step by the methods of induction, contrast and summary.
