物理教育的核心内容是促进学生对概念的理解，本研究的目的是探查学生关于电磁学中静电平衡的迷思概念。首先通过已有的前概念和迷思概念研究成果的文献综述，了解国内外研究现状，然后将学生在课上讨论关于静电平衡的概念测试题的录音材料转换成文字，通过分析文字材料统计学生的作答情况，并探究和整理学生在该部分知识中存在的迷思概念，将迷思概念编码归类，在此基础上，将测试学生的关于静电平衡的问题编制成二阶测试题，并提出教学建议。

The core content of physical education is to promote students'understanding of the concepts，the purpose of this study is to probe the student about the misconception of electrostatic equilibrium．First by the literature review about the existing research results of the preconception and misconception，the domestic and foreign research present situation was understood．Then the investigator converted the recording materials of the discussion of the concepts test of electrostatic equilibrium among the students in class into the text．By the analysis of the text material the distribution of choices was counted．Meanwhile the investigator explored and organized the misconception of the students existing in this part of knowledge，and numbered and classified the misconception．Based on this，the test questions about electrostatic equilibrium were compiled into the second order test，and the investigator put forward some teaching suggestions．
