摘要
在声速测量实验教学中,运用Mathematica软件动态模拟李萨如图形,让学生直观了解李萨如图形以及参数改变对图形的影响,可帮助学生更好地理解李萨如图形法测量声速的实验原理及实验操作技巧,加深对简谐振动合成的理解。介绍了在实验教学中的具体做法。
In the sound velocity measurement experiment teaching,Lissajous figure is dynamically simulated with Mathematica software to let students intuitively understand Lissajous figure and the influence of parameter change on figure,which can help students better understand the experimental principle and operation skills of Lissajous graphic method for measuring sound velocity and deepen the understanding of the composition of simple harmonic vibration.The detailed steps in experimental teaching are also introduced in this paper.
