摘　　要：研究了伏安法测电阻的基于中学物理实验标配电表参量选择待测电阻的方法,结果表明:既要依据相对系统误差,又要依据匹配条件,综合选择待测电阻;给出了方法运用的实例,深化了伏安法测电阻的认识,奠定了精准设计实验教学的基础.The method of selecting candidate resistance by voltammetry based on the parameters of standard ammeter in middle school physics experiments is studied,the results show that candidate resistance should be selected comprehensively according to the relative system error and matching condition.An example of applying the method is given,which deepens the understanding of measuring resistance by voltammetry and lays the foundation for accurately designing the teaching experiment.
