用一种ZKY-YM数显近距转镜式杨氏模量仪测定金属丝的杨氏模量,主要分析了钢丝因素对实验结果的影响,并最终给出在3 kg质量提供的预拉力下,拉力不超过88.2 N,每次增减质量由1 kg变为0.5 kg的条件下,得到了更加精确的杨氏模量结果.%This paper analyzes some factors of steel wire that influence the measurement accuracy of the Young′s Modulus Experiment by a ZKY-YM experimental instrument.And eventually given under 3 kg quality to provide strong,no more than 88.2 N,every time increase or decrease in quality from 1 kg to 0.5 kg,the young′s modulus of more accurate results are obtained.
