用等容法测定了新型低全球变暖潜值制冷剂三氟乙烯（R1123，CF2 <$CHF）和3，3，3-三氟丙烯（R1243 zf，CF 3 CH <$CH2）在278 ~ 377 K温度范围内的饱和压力。在ITS-90上用25 Ω标准铂电阻温度计测量温度。用数字石英压力传感器测量压力。温度和压力的实验不确定度估计分别为5 mK和1 kPa（k = 2）。根据目前的饱和压力数据，已制定了新的制冷剂的饱和压力关联式。测定了R1123和R1243 zf的临界压力。
Saturation pressures for new low global warming potential refrigerants trifluoroethene (R1123, CF2═CHF) and 3,3,3-trifluoropropene (R1243zf, CF3CH═CH2) were measured by the isochoric method for temperatures between 278 and 377 K. Temperature was measured with a 25 Ω standard platinum resistance thermometer on ITS-90. Pressure was measured with a digital quartz pressure transducer. The experimental uncertainties in temperature and pressure are estimated to be 5 mK and 1 kPa (k = 2), respectively. New saturation-pressure correlations for the refrigerants have been formulated based on the present saturation-pressure data. The critical pressures of R1123 and R1243zf were also determined.
