摘　　要：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243.15～363.15 K,压力范围为0.54～11.49 MPa,黏度和密度实验测量的不确定度分别为±2%和±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.
