论文摘要
这项研究开发了一种基于曲线拟合技术测量液体表面张力的简单方法。在这项研究中，通过求解二-D Young-Laplace方程来得出表面张力的显式液滴轮廓函数，并且派生的配置函数优于现有的近似概况函数。通过将派生的配置文件函数与检测到的液滴图像数据拟合，然后获得了液体表面张力。所提出的方法不依赖任何新工具，在原则上截然不同，与传统方法更简单。
This study developed a simple method to measure liquid surface tension based on curve fitting technique. In this study, the explicit lying droplet profile function in terms of surface tension was derived by solving 2-D Young-Laplace equation exactly, and the derived profile function was superior to the existing approximate profile functions. By fitting the derived profile function with the detected droplet profile image data, the liquid surface tension was then obtained. The proposed method does not rely on any new instrument, it is quite different in principle and simpler than the traditional methods.
