在声波演示实验中,可以利用薄膜的受迫振动演示稳定的李萨如图形.在声波驱动下,薄膜的振动可以分为垂直于薄膜表面的横向振动及平行于薄膜表面的纵向振动,本文对理想状态的简化模型的力学原理进行了分析和探讨.

In the sound wave demonstration experiment, stable Lissajous figure produced by forced vibration of thin film can be observed. Thin film vibration forced by sound wave can be considered in two ways, one is transverse vibration which is vertical to the face of the thin film, the other is longitudinal vibration which is parallel to the face of the thin film. The purpose of this study is to propose a simplified model for analysing the...
