对比法在静电场理论教学中的应用

摘要

Generally,electrostatic field theory is in leading position within a course of electromagnetic field theory, therefore,its effect of teaching and learning is directly related to that of the course.A typical case with respect to boundary value problem for electrostatic field theory is designed.In order to overcome difficulties,such as abstract concepts,complex derivation process,a comparative approach of teaching and learning is chosen.Thus,its effect is enhanced.The comparisons include solving methods(analytical method versus numerical method),teaching and learning methods(lecture method versus demonstration method),and teaching and learning means(traditional means versus modern means).This case will attempt to provide a reference for teaching and learning of the course.%静电场理论一般处于电磁场理论的开篇位置,其教学效果直接关系到整科电磁场理论的教学成败.设计了一个静电场边值问题的典型案例.为克服概念抽象、过程复杂等困难,教学中应用求解方法(解析法与数值法)的对比,教学方法(讲授法与演示法)的对比和教学手段(传统手段与现代手段)的对比等方法,提高了教学效果,为电磁理论的教学提供参考.
