摘要
无论是物理专业还是非物理专业,对于麦克斯韦方程组的学习都有一定的难度.而该组方程对全面理解电磁场理论是至关重要的,因此必须从理论体系和知识结构上去分析,才能抓住本质学到真谛.以电容器"隔直、通交"的特性为突破口,通过其充放电的简单实验现象,引出"位移电流"的概念.由位移电流和涡旋电场得到四个偏微分程,该方程组的物理意义精确地涵盖了电磁场理论的基本内容.
Learning Maxwell＇s equations is a difficult point whether for physics majors and non-physics majors.And the set of equations is critical for a comprehensive understanding of electromagnetic theory.Therefore the analysis of a theoretical system and knowledge structure is the essence of learning the true meaning.In this study,＂blocking,through diplomacy＂ is taken as a breakthrough by the simple experiment of its charge and discharge,and finally leading to the concept of displacement current.Four partial differential equations have been obtained by the displacement current and the vortex electric field,the physical meaning of the equations accurately covers the basic electromagnetic theory.
