| 摘 要： | Mathematica软件的Manipulate命令能做范围广泛的人机互动的应用,文章将其用来做示波器实验的拍现象和李萨如图的仿真和研究。用Mathematica软件的动态作图说明了李萨如图形移动的原因是频率与理想频率存在微小的差别,给出了如何根据图形的移动情况对频率进行调节使得图形稳定的方法,在实际操作中是可行的。

| Abstract: | Manipulate command of Mathematica software can do a wide range of human-computer interaction applications. It is used for simulation and researching of beat phenomenon and Lissajous figure in oscilloscope experiment. The slight difference between the fre- quency of moving Lissajous graphics and the ideal frequency is given by the dynamic mapping of Mathematica software. The method of frequency adjustment for moving graphics is feasible in practice. |
