摘　　要："导体表面是等势面","等势面与电场线处处正交",是物理学中的基本概念。通过对电磁学中两道概念不清晰的题目的讨论,使学生明确了在学习物理学的思想和方法时,应克服概念模糊、研究缺乏有效性讨论等现象,明确了物理概念的重要性,加深了对上述基本概念的认识和理解。＂Equi-potential surface on the surface of a conductor＂ and that ＂an equi-potential surface is always perpendicular to the electric field lines＂ are basic concepts in physics.When learning the methods to solve physics problems,students are encouraged to have productive discussions in order to avoid vague concepts.Through discussions on the two practice questions in electromagnetism in this paper,students will deepen the understanding of the concept of equi-potential in conductors.
