摘要
表面张力是影响多相体系的相间传质和反应的关键因素之一,是重要的液体物理性质。本文着重介绍了几种液体表面张力的测定方法(包括毛细管上升法、Wilhelmy盘法、悬滴法、滴体积法、最大气泡压力法),包括这几种方法的测定原理、优缺点及改进方法,特别指出了宽温度和压力范围的表面张力测定存在的问题,实验方法的选择及表面张力测定方法的发展趋势。
Surface tension, one of the key influence factors to the mass transfer and reaction of multiphase system, is an important physical property of liquid. The basic principle, advantage, disadvantage and the improvement for measuring liquid surface tension with different methods were described. The methods were capillary rise method, Wilhelmy plate method, pendent drop method, drop volume method, maximum bubble pressure method. The problems in the surface tension measurement of wide temperature and pressure range, the chosen of experimental methods and the development tendency of these were introduced especially in this paper.
