利用电像变换法巧解电学题——感知物理科学思维的魅力

Using Electrical Image Transformation to Solve Electrical Issues Skillfully

详细介绍了如何利用电像法求解复杂电学题、运用时需注意的问题及其体现的等效的思维魅力.包括无限大接地平面和接地导体球这两类典型题,以及电像变换法在解高考题和物理竞赛题时的妙处.电像变换法就是等效思想的应用,在高中阶段,并不要求学生进行严格地推理论证,只需深入理解其思想的精髓,本文重在解题中渗透电像变换法的物理思想及其"科学思维的魅力".

This paper introduces in detail how to use the electric image method to solve complex electrical problems,the problem needing attention when using and the equivalent thinking charm.Including how to solve the problems of the infinite grounding plane and the grounding conductor ball by using the method of electric image transformation,respectively,and the beauty of solving high examination questions and physics competitions by using the method of electric image transformation.The electric image transformation method is the application of the equivalent thought,in the high school stage,the student does not require to carry on the rigorous reasoning demonstration,only needs to understand deeply its thought essence,therefore this article focuses on the infiltration electric transformation method's physics thought and"the scientific thought charm"in the problem solving.
