表面张力是影响多相体系传质和反应的关键因素之一，是液体的一项重要物理性质。介绍了毛细上升法、威氏平板法、悬滴法、滴容法、最大气泡压力法等不同方法测量液体表面张力的基本原理、优缺点及改进，重点介绍了宽温压范围表面张力测量中存在的问题、实验方法的选择及发展趋势。
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.
