三维振动轨迹曲线演示方法

Demonstration of three dimension vibration curves

在传统的振动与波动学教学中 ,只能通过机械装置对个别振动与波动现象进行演示。利用Mathematica软件 ,结合计算机系统的图像和声音处理能力 ,可以直观地显示各种振动与波动时空曲线及轨迹曲线 ,并能输出任意振动方程对应的声振动 (声音 ) ,全面突破传统教学手段的局限。

In the traditional teaching process of vibration and wave, only a few vibration and wave phenomena can be demonstrated by means of mechanical devices. By using Mathematica software and the capability of processing pictures and sounds, various vibrations and wave curves can be displayed visually. Every kind of sound corresponding to audio vibration equation can be sent out, which breaks through the limitation of the traditional methods.
