| 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。

| Abstract: | 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,subsequently increased and finally decreased with the increase of ethanol proportion,which was helpful for the further research of ethanol-gasoline. |

| Keywords: | ethanol-gasoline isoteniscope method saturated vapor pressure |
