| 摘 要： | 通过对钢丝杨氏弹性模量测量数据的误差分析,找出了对总误差影响最大的两个直接测量数据,即：钢丝直径和标尺读数的平均值,为了合理地减小这两个量的误差,提出了改进实验的方法,即：预加砝码.

| Abstract: | Based on measurement data processing and error analysis of Young’s Modulus,the two direct measurement values which have the greatest impact on the overall error are found out,namely,the diameter of the steel wire and the mean value of the scale.In order to reduce the errors of the two values reasonably,the pre-weight method is suggested. |
