一、前言 HFC-134a目前被认为是CFC-12较为理想的替代物。迄今为止,国外正式发表的HFC-134a的表面张力数据及相应的关联式只有美国NIST的Chae等以及日本庆应大学的Okada等两份材料。表1汇集了这些情况。我们最近采用毛细管法,也初步测取了HFC-134a的表面张力数据。本文将详细介绍作者自行研制的装置和测试结果,并给出了表面张力随温度变化的关联式。 I. Introduction HFC-134a is currently considered as an ideal substitute for CFC-12. So far, the data of surface tension of HFC-134a officially published in foreign countries and the corresponding correlations are only two materials such as Chae of NIST of USA and Okada of Keio University of Japan. Table 1 brings together these situations. We recently adopted the capillary method, but also preliminary measured the surface tension of HFC-134a data. This article describes in detail the devices and test results developed by the authors themselves, and gives the correlations of surface tension with temperature.
