摘　　要：基于传统的用拉伸法测量钢丝的杨氏模量实验,利用CCD传感器技术和Origin pro 7.5图像处理软件,分四种加力方式进行实验,求出不同的杨氏模量,得出了初步的变化规律,加力越快则杨氏模量越小,其原因供同行共同探讨。It based on the traditional stretching method was used to measure young's modulus of steel wire ex-periment,using CCD sensor technology and Origin pro 7. 5 image processing software,four kinds of strength ex-periment in the form of the young's modulus of different,the changing rule of the obtained preliminary,the fas-ter and stronger,the smaller the young's modulus,the reason for the colleague to discuss.
