| 摘 要： | 研制了一套新型压力-温度-体积（PVT）性质测试系统．该系统由自行开发的测控软件实时测控，温度测量精度可达±10mK，压力测量系统最大不确定度为±1．2KPa．利用新的测试系统对294～351K温度区间的Hydrofluorocarbons（HFC）-245fa饱和蒸气压进行了研究．实验结果表明，HFC-245fa的测量值与公认文献值的平均偏差小于0．03％，最大偏差小于0．484％，结果与文献值吻合较好．

| Abstract: | A new experimental system of PVT measurement automatically controlled by a computer has been developed. The overall pressure and temperature uncertainty is about ±1.2 KPa, and ±5 mK, respectively. The vapor pressures of HFC-245fa were measured in the temperature range from 294 to 351 K with the new experimental system, and the experimental results indicated that the average deviation between experimental data and the equation provided in the literature was below 0.03%, and the standard deviation was below 0.484%. Which approved that the new experimental system is reliable. |
