Surface tension measurements are a central task in the study of surfaces and interfaces. For liquid metals, they are complicated by the high temperatures and the consequently high reactivity characterising these melts. In particular, oxidation of the liquid surface in combination with evaporation phenomena requires a stringent control of the experimental conditions, and an appropriate theoretical treatment. Recently, much progress has been made on both sides. In addition to improving the conventional sessile drop technique, new containerless methods have been developed for surface tension measurements. This paper reviews the experimental progress made in the last few years, and the theoretical framework required for modelling and understanding the relevant physico-chemical surface phenomena.
表面张力测量是研究表面和界面的核心任务。对于液态金属，由于这些熔体的高温和高反应性，测量变得复杂。特别是，液体表面的氧化与蒸发现象相结合，需要严格控制实验条件，并进行适当的理论处理。最近，在这两个方面都取得了很大的进展。除了改进传统的悬滴技术外，还开发了新的无容器方法来测量表面张力。本文综述了过去几年取得的实验进展，以及为模拟和理解相关物理化学表面现象所需的理论框架。
