Many factors are known to affect the vibration characteristics of sessile micro-droplets, such as surface tension, liquid densities, and contact angles. In this study, the vibration signals of the sessile micro-droplets under the conditions of different contact angles and viscosities were obtained using experimental processes. A theoretical model was designed based on the experimental phenomena in which the contact angles and contact lines were fixed. Then, similar to the vibrations of solid elastic film, it was assumed that the vibration waves of the sessile droplets existed within a certain thickness of the droplet surfaces, which provided a theoretical basis for the periodic correction coefficients. It was found that although the model was simple, it was in good agreement with the experimental results.

已知许多因素会影响固着微液滴的振动特性，例如表面张力、液体密度和接触角。在这项研究中，使用实验过程获得了在不同接触角和粘度条件下固着微液滴的振动信号。基于接触角和接触线固定的实验现象设计了理论模型。然后，类似于固体弹性膜的振动，假设固着液滴的振动波存在于液滴表面一定厚度内，这为周期修正系数提供了理论依据。发现模型虽然简单，但与实验结果吻合较好。
