建立了一套沿等轴线测量P-ρTX(压力-密度-温度-组成)特性的实验装置。经过压力传感器的标定和样品容器内体积的测定，通过对纯HFC-134a(1，1，1，2-四氟乙烷)等温线的测量，证实了实验装置的重现性。测定了50质量%HfO-1234ze(E)(反式-1，3，3，3-四氟丙烯)+50质量%HfC-32(二氟甲烷)混合物和75质量%HfO-1234ze(E)+25质量%HFC-32混合物的PρTX性质，分别测定了包括128PρTX性质数据点在内的5条等温线和包括188PρTX性质数据点在内的7条等温线。临界压力是由目前接近临界密度的临界压力相对于临界温度确定的。汽液平衡时的压力和温度之间的关系是由压力中心图解确定的。
An experimental apparatus for measuring PρTx (pressure-density-temperature-composition) properties along isochores was constructed. After the calibration of pressure sensor and the determination of the inner volume of sample vessel, the reproducibility of the experimental apparatus was confirmed by the measurement of isochores for pure HFC-134a (1, 1, 1, 2-tetrafluoroethane). The PρTx properties of the 50 mass% HFO-1234ze (E)(trans-1, 3, 3, 3-tetrafluoropropene)+ 50 mass% HFC-32 (difluoromethane) mixtures and those of the 75 mass% HFO-1234ze (E)+ 25 mass% HFC-32 mixtures were measured for five isochores including 128 PρTx property data points and for seven isochores including 188 PρTx property data points, respectively. The critical pressures were determined from the present isochores close to the critical density against the critical temperature. The relationship between pressure and temperature at vapor-liquid equilibrium was graphically determined from thepresentisochores.
