Abstract
This research presents an experimental study on the Faraday instability in one-dimensional cells filled with a mixture of water and glycerol, and for a range forcing frequency between 10 and 60 Hz. It showed that for a particular forcing frequency, whose value depends on the width of the cell, an anomalous surface oscillation arises, that appears as a large wavelength mode oscillating subharmonically with respect to the normal modes predicted by the linear stability analysis. Since all others studied forcing frequency, the observed modes are in agreement with the ones theoretically predicted.
Key words: Faraday Instability, non-linear dynamics

本研究提出了一个实验研究的法拉第不稳定性的一维细胞充满水和甘油的混合物，范围强迫频率在10和60赫兹之间。结果表明，对于特定的强迫频率，其值取决于单元的宽度，会产生异常的表面振荡，其表现为与线性稳定性分析预测的正常模式相比，以次谐波方式振荡的大波长模式。由于所有其他研究强迫频率，观测到的模态与理论预测的模态一致。关键词:法拉第不稳定性，非线性动力学，PACS: 47.20博士,47.20。全球之声,47.35。+我,47.54 + r
