超声传感器测不同浓度溶液中的声速及研究

摘要

It describes using an ultrasonic sensor,etc. Obtained a new method by a phase comparison method in the speed of sound measured at different concentrations of the solution. And using the C programming lan-guage for data processing, avoiding cumbersome calculations and the errors is smaller, which get the conclusions more reasonable.%介绍了超声传感器等的应用，得出了通过相位比较法测量在不同浓度溶液中的声速并进行研究的一种新方法。同时利用C语言编程进行数据处理，避免了烦琐的计算且误差较小，使结论更合理。
