摘　　要：利用静态法(等压计法)对几种不同混合比例的乙醇汽油饱和蒸气压进行试验研究,得到不同比例的乙醇汽油饱和蒸气压随温度变化的曲线。在此基础上,分析同一温度下不同乙醇汽油饱和蒸气压试验数据,发现在一定的温度下,随着混合燃料中乙醇比例的上升,其饱和蒸气压会出现一个由增大到减小,再增大到再减小的复杂过程。这对于乙醇汽油的进一步研究及推广将有着积极的指导意义。With the isoteniscope method, the saturated vapor pressure of different proportional ethanol-gasoline was researched and the curves of saturated vapor pressure with temperature were acquired. Comparing the saturated pressure of different ethanol-gasoline at the same temperature, it was found that the saturated pressure increased, then decreased, subse- quently increased and finally decreased with the increase of ethanol proportion, which was helpful for the further research of ethanol-gasoline.
