学习了真空中的静电场一章,接着学习导体及电介质在电场中存在时,它们与电场的相互影响、相互作用,对于学习电介质这部分教材,学生往往觉得内容杂乱,不得要领,以下提出对这部分教材的安排处理,企求以较少的学时,讲清这个问题,以利学生掌握好这部分 Learning a chapter on the electrostatic field in a vacuum, and then learning the mutual influence and interaction of conductors and dielectrics in the electric field when they exist in an electric field. Students often find the contents messy and unimaginable for the purpose of learning the dielectric. This part of the teaching material arrangements for the treatment, seeking to fewer hours, make clear this problem, in order to facilitate students to master this part
