甘草稀溶液中超声波波速随溶液浓度的振荡现象分析

本文利用超声光栅衍射原理，对甘草溶液作了不同浓度组分下的衍射光谱分析。通过分析发现，在超声波的作用下，超声波的波速随着浓度出现了振荡现象。然后利用热力学中的相变理论与流体力学原理对其振荡过程作出了理论分析，同时也给出了由于液体中出现微气泡时，对超声波波速的校正公式。

Analysis of Oscillatory Occurrences in the Liquorices Solution about the Wave Velocity of the Ultrasonic along with Solution Concentration

Using the supersonic diffraction grating diffraction principle,the paper made different density component diffraction spectrum analysis to the hay solution.Through the analysis we discovered under the ultrasonic wave function, the ultrasonic wave velocity produced the oscillatory occurrences along with the density.This article uses thermodynamics to change the theory and the hydromechanics principle has made the theoretical analysis to its vibration process,simultaneously has also given ultrasonic wave velo...
