摘要

借助 Matlab 软件分别采用逐差法和最小二乘法对拉伸法测量杨氏弹性模量实验进行数据处理，利用 Matlab GUI 设计数据处理交互式界面，通过在 GUI 界面输入测量数据和实验参数，绘制出了拟合直线图，实现了杨氏模量值及其不确定度的程序计算，分析了两种方法求得的实验结果。数据处理过程操作简单，提高了学生运用软件的能力和实验效率。

Abstract:

The successive differential method and the least square method are used to process the experimental data of Young’s Modulus Measurement Based on Matlab．The Matlab GUI is used to design an interactive interface for data processing and the fitting diagram plotting．Moreover，the experimental results are analyzed by inputting the measured data and experimental paramete．The operation is simple，which can improve students’ ability to use software and the experimental efficiency．

Key words: Young’s modulus Matlab GUI the method of successive difference least square method
