摘要
对拉伸试件拉断后标距段长度测量方法进行改进，提出一种新的拉伸试件的测量方法，得出测量结果，并对所进行的实验进行讨论。新方法能提高测量精度。
Through improvement of measuring method of post out-break lenghth of tensile sample,a new measuring method of stretch sample was put forward, experiment was done and obtained the result that new method can raise the measured precision.
