在电路教学中培养学生的数学应用能力

在电路和电工技术教学中加强数学方法的运用是提高大学生数学应用意识和能力的重要手段,同时还可以加深对电路概念和方法的理解。本文结合置换定理、叠加定理、非正弦周期电路、暂态电路、正弦稳态电路相量分析以及电阻的星形和三角形连接的等效变换等教学内容,介绍了应用数学方法建立电路概念的体会,供读者参考。

The Cultivations of Math Application Skill for College Students in Electric Circuit Teaching

It is an important measure to improve the math application consciousness and abilities for college students by enhancing the math methods in the Electric Circuit and Electro-technical courses teaching. At the same time, this can also make the students understand circuit concepts and analysis methods clearly and deeply. In this paper, the teaching experiences o~ applying math theories to build circuit concepts and analysis methods in the Electric Circuit course are introduced by means of substitution theorem, superposi- tion theorem, non-sinusoidal periodic circuits, transit state circuits, phasor analysis for sinusoidal circuits, as well as the equivalent transformations between Y-type and △-type configurations of resistors. Readers may take these ways as references in teaching students.
