用超声光栅仪测量液体浓度

Measuring liquid concentration with ultrasonic grating

把酒精作为研究对象并且逐步的改变其浓度,利用产生超声光栅的原理测量必要的物理量,再进一步的计算出超声波声速,最后利用所计算出的速度与浓度的关系来实现对液体浓度的定量分析,从而实现超声光栅仪测量液体浓度的目的。

In this paper, ultrasonic grating is used to achieve the ultimate purpose of measuring the concentration of liquid. Based on the liquid concentration measurements a feasibility, method is provided. Alcohol is the subject investigated. The necessary physical quantity is measured with ultrasonic grating and the ultrasonic velocity is calculated. Finally the relationship between the speed and concentration is used for quantitative analysis of liquid concentrations.
