电学仪表读数问题浅议

Discussion on Reading Issue of Electrical instruments

电学仪表读数问题反映出中学物理课程、教学和评价在一定程度上存在不一致和不匹配.本文据于测量过程中偶然误差和系统误差的权重分析,对电学仪表读数的常用方法进行讨论,旨在促成中学物理课程、教学和评价的联动发展.

The different dealing criterion of significant figure for electrical instruments shows partly that inconsistency and mismatch of physics course, teaching and evaluation in senior middle school. Based on the proportion analysis of accidental error and systematic error in the measurement process, this paper discusses the dealing criterion of significant figure for electrical instruments, aiming to promote the linkage development for the physics course, teaching and evaluation.
