In order to enable students to learn the electrostatic field description experiment lesson well,itanalyzes and discusses three problems existing in the lecture notes and operation of this experiment; unclearideas on the experimental lecture notes , practical problems on the experimental equipment , lack of guidancemethods on the experimental operation, etc. Based on the classroom teaching and students’ various actualsituations ,it puts forward the elaboration ideas on adjusting the experimental lecture notes,and the selection ofexperimental equipment should be simple and reliable ,teachers should be good at summarizing coping methodsand other improvement methods.I hope it can be used for reference by instrument manufacturers , teachingcolleagues and students.
