摘　　要：将MATLAB应用于物理实验教学中,通过编程绘制扭摆法测量刚体转动惯量的实验过程动画,将抽象复杂的实验过程具象化,有利于讲解过程中辅助学生理解;将实验数据导入工具包Curve Fitting Tool进行数据处理,绘制函数图像得出物体转动惯量的数据结论,不仅能够得到精确的实验数据,更能加深学生对于实验原理及各参数之间关系的理解.随着各类信息化编程软件发展,实验过程可视化、实验数据精确化处理成为了课堂教学的重要辅助,提升实验教学的趣味性并且锻炼学生的物理感性思维.Using the visualization of MATLAB,we can draw the experimental process to show the animation of measuring the moment of inertia of rigid body by torsion pendulum method, and the abstract and complex experimental process is visualized, which is conducive to assisting students to understand in the explanation process.Import the experimental data into the Curve Fitting Tool for data processing, and draw the function image and get the data conclusion of the moment of inertia of the object, which can not only get the accurate experimental data, but also deepen students′ understanding of the experimental principle and the relationship between the parameters.With the development of various information-based programming software, visualization of experimental processes and precision processing of experimental data have become important aids to classroom teaching, increasing the interest in experimental teaching and improving students′ thinking ability.
