摘　　要：从实验方法和实验器材2方面对探究平面镜成像实验进行改进.改变实验方法,利用轴对称定义,简化了传统实验流程,减小了实验误差;改变实验器材,利用磁性材料,解决了平面镜与底座难以垂直的问题以及物点和像点的精准描画问题.改进后的实验装置设计合理、操作简便,适合用于演示实验教学.The experiment of exploring plane mirror imaging was improved from two aspects in this paper,i.e.the experimental method and experimental device.Firstly,the definition of axial symmetry was skillfully used in the experimental method,which simplified the traditional experimental process and successfully reduced experimental errors.Secondly,magnetic material was utilized in the experimental device,which solved the perpendicular difficulty between the plane mirror and the base,and the accurate drawing of object points and image points.The improved device was reasonable in design,simple in operation,which was suitable for demonstration experiment teaching.
