Significant figure of measurement result and its uncertainty in physics experimentZHANG Ying Applied Science Institute, Changchun University, Changchun 130022, ChinaAbstract:This paper devotes to the significant figures in the result of a measurement and its uncertainty. Through examples, the paper discusses various problems relevant to the significant figures under different conditions so as to determine the significant figures in the result of a measurement and its uncertainty in physics experiment.[著者文摘]
