基于超声波研究甘油溶液中声速与浓度的关系

Study on the relationship between sound velocity and the concentration of glycerol solution based on ultrasonic

利用时差法测量了超声波在不同浓度甘油溶液中的传播速度。并根据测量结果,给出了超声波在不同浓度甘油溶液中传播的速度与其浓度的关系图及拟合方程。结果表明,超声波在甘油溶液中的传播速度与其浓度呈线性关系。这一结论对进一步研究超声波在其它溶液中的传播特性具有一定的应用和参考价值。

This paper measured the propagation velocity of ultrasonic at different concentration of the glycerol solution, according the measurement results, given the relationship between different concentration of glycerol solutions and ultrasound transmission velocity in the experimental curve and fitting equation. The results show that the ultrasonic propagation velocity and glycerol concentration of the solution is linear. This conclusion has important reference and application to further study the mechanics of materials.
