摘要
本文主要介绍了物理实验中测量结果及其不确定度的有效位数,通过举例,对不同情况下与此相关的问题进行讨论,从而明确测量结果及其不确定度的有效位数的取舍。
This paper devotes mainly to the significant figures in the result of a measurement and its uncertainty, Through examples, the paper discusses on different conditions the various problems relevant to the significant figures as to determine the result of a measurement and its uncertainty of the significant figules.
