摘　　要：分别用替代法、半偏法、等偏法及伏安法等多种经典的设计性实验来测量直流电流表内阻,并对其作了比较分析,目的是使学生学会如何动脑设计实验,增加其对物理实验的探究性学习兴趣.The paper discusses how to increase students' interest in physical experiments through inquiry learning by analysis and comparison of four classical experiments to measure the internal resistance of DC amperemeter: substitution method,half deflection method,equal deflection method and voltammetry.
