醋酸水溶液声速与温度浓度关系研究

Consistence and temperature dependence of ultrasonic velocity in acetic acid-water mixtures

研究了超声波在不同温度、不同浓度醋酸水溶液中的速度传播特性.应用脉冲回波法,检测了醋酸水溶液在16～70℃温度范围及体积分数为10%～75%范围的超声波传播速度,给出了不同浓度及不同温度下的速度与温度关系曲线,实验结果和理论推导基本一致.

In order to study the property of different ultrasonic velocity in different consistence and temperature, Pulse-Echo method is used to study the state of acetic acid in water . Ultrasonic velocity of acetic acid in water as a function of consistence has been measured for the temperature range 16～70℃. The velocity-temperature curves under different consistencies and the velocity-consistence curves under different temperatures are plotted and the reasons are given.
