摘要本文分别采用雷德法和参比法对分析纯乙醇和93#汽油的饱和蒸气压进行了实验测量，实验研究了装样温度等条件对饱和蒸汽压测试结果的影响，分析了影响这两种测定方法的主要因素，并探讨了对这两种方法测量时的优缺点。研究结果表明，装样温度对饱和蒸气压的测定结果有较为显著的影响，装样温度较低时所测得的饱和蒸气压较高，这可能主要是由于装样温度较低时，装样过程中样品轻组分的挥发较少；对雷德法和参比法可能造成的误差的对比分析表明，参比法受环境温湿度等因素的影响较小，其可能更适用于饱和蒸气压的精确测量。73342

Title The measurement method of the liquid fuel saturated vapor pressure
Abstract In this paper, Reid method and reference method was respectively used to analytical reagent AR ethanol and 93 # gasoline saturated vapor pressure of experimentally measured，the impact loading the sample temperature on the saturation vapor pressure of the results had experimentally studied, the influence of these two determination of the main factors, and doing discussion of the advantages and disadvantages by these two methods of measurement。 The results showed that the sample loading temperature have a more significant impact on the determination of the saturated vapor pressure, low sample loading when the measured temperature higher saturated vapor pressure, which may be mainly due to the low temperature sample loading, sample loading during less volatile sample light component; Reid method and reference method result error may in the comparative analysis showed that the reference method less affected by factors such as ambient temperature and humidity, which may be more suitable for the saturated vapor pressure accurate measurement。
Keywords the Reid method reference method the saturated vapor pressure
