利用振动弦黏度／密度计对1，1，1，2，3，3，3七氟丙烷（HFC-227ea）的黏度和密度进行了实验研究，温度范围为243．15-363．15K，压力范围为0．54-11．49MPa，黏度和密度实验测量的不确定度分别为4-2％和4-0．2％。利用获得的实验数据分别拟合了HFC-227ea黏度和密度方程。黏度实验数据与方程的平均绝对偏差为0．71％，最大绝对偏差为2．02％；密度实验数据与方程的平均绝对偏差为0．05％，最大绝对偏差为0．15％。在本文实验范围之内，与文献实验数据进行了比较，本文实验结果与文献数据吻合较好，为HFC-227ea的进一步应用研究提供了可靠的基础数据。
The viscosity and density of l,l,l,2,3,3,3-Heptafluoropropane （HFC-227ea） were reported at temperatures from 243.15 K to 363.15 K and at pressures up to 11.49 MPa. The measurements were performed simultaneously using a vibrating-wire instrument operated in the forced mode of oscillation. The overall uncertainties of these results are ±2.0% in viscosity and ±0.2% in density. Correlations for both the viscosity and the density are presented. The average absolute deviation and the maximum absolute deviation of the viscosity measurements from the correlation are 0.71% and 2.02% respectively, and for density are 0.05% and 0.15%, respectively. Comparisons between measurements of this work and literatures are presented.
