摘　　要：在液体饱和蒸气压测定实验装置中,引入微流量调节阀对缓冲储气罐进行改造,使导入系统的空气流量精确可控,解决了调压时需反复调节、操控难、空气倒灌等问题,缩短了实验时间。使用该装置以静态法测定了乙醇的饱和蒸气压,在实验教学中获得了良好的效果。A micro-flow regulating valve was introduced into an experimental device used for liquid vapor pressure measurements,to enable the accurate and control of the pressure of the system and address the problem of backward air flow into the experimental system.Desirable results were obtained in the experimental process with the use of the micro-flow regulating valve in the experimental device.
