【摘要】 以三线摆测量转动惯量实验为例采用字符查找、比较及连接等方法研究了利用MATLAB的GUI功能开发大学物理实验数据正确与否的检验程序,包括仪器读数的检验以及有效数字的运算。可以通过图形用户界面方便地实现实验数据的输入、输入数据正确性与否的检验以及有效数字运算功能。同时研究了利用MATLAB GUI实现实验数据数据库存取方法。更多还原

【Abstract】 To suit the operations of significant digit,a study to check the input physical experiment data utilizing MATLAB GUI function was performed in this paper taking experiment of measuring moment of inertia based on three line pendulum as an example.Character handing methods including seeking,comparing and connecting were used to develop significant digit operations program and check program of the read-out of the meters.The experimental data can be input from GUI of MATLAB conveniently.And methods of Matlab connecting to database, importing data into Matlab from a database to deal with and exporting data from Matlab to a record in a database were discussed.更多还原
