用声速法在线测量强酸溶液的浓度

On line Measurement of the Concentration of Strong Acid by Using Ultrasonic Velocity

超声波技术为化工溶液浓度的测量提供了可能。由于强酸中超声波速度在一定浓度上存在着极值现象，因此超声波测量溶液浓度的技术只适用于某些浓度范围。作者根据超声波速度与强酸溶液浓度的关系提出了一种用声速法测量强酸浓度的方法，该法特别适用于化工厂生产液的在线测量。

Ultrasonic techniques can be used to measure the concentration of chemical solutions.Based on the relationships between the ultrasonic velocity and the concentratiojn of acid solution and the temperature,a method measuring the concentration of strong acid has been presented.It is very useful for the on line measurement of chemical plants.
