| 摘 要： | 提出了超声相位差法测定乙醇汽油溶液浓度的新方法,根据该方法设计并制作了超声在线测定仪.利用该仪器建立了温度在290 K时乙醇体积浓度在3％ ～24％的乙醇汽油溶液浓度与相位差之间的关系式.实验结果表明,该超声测定仪能够实时和精确地测定乙醇汽油溶液中乙醇体积浓度,该仪器为精确测量车用乙醇汽油和其他二元溶液开辟了新途径.

| Abstract: | A new way of ethanol gasoline concentration determination is proposed based on the ultrasound phase differenc e method.The on-line concentration measuring instrument is also designed by t he method.When the temperature is 290K and ethanol gasoline volume concentration is at between 3% and 24%,we use the instrume nt to establish relationship between ethanol gasoline concentration and phase. The experimental results show that the ultrasound concentration measuring instrum ent can not only measure ethanol volume concentration in ethanol gasoline soluti on accurately and real-time,but also come up a new way for measuring vehicle ethanol gasoline and other binary solution accurately. |
