提出了一种改进的测量液态金属表面张力的方法。用摄像机观测了电磁悬浮液态金属液滴的表面振荡，并利用数字图像处理技术对振荡的频谱进行了估计。文中讨论了理论背景，并对实验装置进行了描述。此外，还给出了对FeNi样品的初步结果，并对未来的实验进行了展望，包括粘度的测量。
An improved method for measuring the surface tension of liquid metals is proposed. Surface oscillations of an electromagnetically levitated liquid metal droplet are observed by a video camera and digital image processing is used to evaluate the spectrum of oscillations. A discussion of the theoretical background and a description of the experimental apparatus are presented. In addition, preliminary results on an FeNi sample, and an outlook for future experiments, including the measurement of viscosity, are given.
