研究了全球变暖潜势（GWP）小于1的HFO-1123和HFO-1234ze(E)以及HFO-1123/HFC-32和HFO-1234ze(E)/HFC-32二元混合物的表面张力测量数据。在267 K至307 K的温度范围内测量了流体的毛细常数和表面张力，毛细上升的差异传播不确定度为±0.23 mN m。在所选择的预测方法中，DiNicola等人（2018）的相关性与HFO-1123和HFO-1234ze(E)的测量表面张力最吻合。为了预测HFO-1123/HFC-32和HFO-1234ze(E)/HFC-32的表面张力，根据实测数据建立了经验关联。
The study presents the surface tension measurement data of HFO-1123 and HFO-1234ze(E) with global warming potential (GWP) of less than 1 and of binary mixtures HFO-1123/HFC-32 and HFO-1234ze(E)/HFC-32. The capillary constant and surface tension of the fluids are measured across temperatures in a range of 267 K to 307 K with a differential capillary rise with a propagated uncertainty of ±0.23 mN m. Among the selected predicting methods, the correlations of DiNicola et al. (2018) exhibit the best agreement to the measured surface tension of both HFO-1123 and HFO-1234ze(E). In order to predict the surface tension HFO-1123/HFC-32 and HFO-1234ze(E)/HFC-32, empirical correlations are proposed based on the measured data.
