摘要
大学物理课程对于静电平衡这一知识点的教学,通常是介绍基本原理之后,简单列举几个实例,而没有对静电平衡理论进行深层次的理论挖掘.另外,在举例过程中,也未能对静电平衡理论在工程实践中的具体应用细节进行讲解.针对这些问题,通过理论分析与史料分析相结合,详细论述了静电平衡理论与库仑定律的关系及静电屏蔽有效性问题,再通过避雷针这一具体实例,结合国家标准,对静电平衡理论在工程实践中的应用细节进行了阐述.实践表明,这种理论挖掘与工程实践的结合,更有助于学生对静电平衡理论的深层次理解及对工程实践应用方面更具体的认知.
The teaching about electrostatic balance in college physics courses is usually followed by the introduction of basic principles and a few simple examples,instead of the theoretical exploration in depth.In addition,the detailed application of the theory in engineering practice cannot be explained in the process.In view of the above problems,the relationship between electrostatic balance theory and Coulomb’s law and the effectiveness of electrostatic shielding were discussed by combining theoretical analysis and historical data analysis in detail.Again through the specific example of lightning rod,combined with the national standards,the detailed application of electrostatic equilibrium theory in engineering practice was introduced. Practice has proved that the theory mining combined with the engineering practice,can more help student to understand the electrostatic equilibrium theory deeply and to perceive the practical engineering application specifically.
