微幅振荡流体表面波图谱显示方法

Surface Wave Visualization for Liquid in Micro amplitude Vibration

本文介绍一种能够清晰显示微幅高频振荡的流体表面波图谱结构的方法和产生高达１００Ｈｚ频率、波幅为毫米以下的流体表面波的实验装置，即改进了ＦＡＲＡ－ＤＡＹ实验装置。用本实验装置和显示方法获得了精美的波幅图，并就几种波图作了简要说明。

A flow visualization method which can clearly visualize the surface wave patterns of micro amplitude vibrating liquid is presented. An apparatus which may produce the liquid surface waves with amplitude less than one micron and frequency up to 100Hz is also reported. Exquisite wave pattern pictures obtained by the method are shown. Several types of wave pattern are explained briefly.
