【摘要】 电磁场教材对梯度算子的运用主要局限于无旋场位函数的引入。本文提出灵活运用梯度算子的电磁场教学方法,基于物理量量纲分析,运用梯度算子深入挖掘物理概念的内涵,不同途径引入位函数的概念,使教学内容成为有机整体,巧妙地将梯度算子用于典型问题求解,增加学生的学习兴趣,提高教与学的效率。更多还原

【Abstract】 Aimed to limitation of gradient operator which is used to introduce scalar potential for analyzing irrotational fields in curriculum of Electromagnetic Field, a novel teaching method of agile exploitation of gradient operator is proposed in this paper. Based on dimensional analysis of physical quantities, implications of concepts are deeply mined and scalar potential is introduced in different ways that made the whole content tightly be connected. Students’ interesting is stimulated and efficiency of both teaching and studying is raised by applying gradient operator to typical problem solving.更多还原
