Sound velocity and acoustic nonlinearity parameter for fluids. Thermodynamic premises
摘要：
本文提出了几种流体的声速和B/A非线性参量的新的理论公式。考虑了气体的半理想模型和范德华模型，并与实验数据进行了比较。液态水状态方程模型由Jeffery和Austin的解析方程给出，并根据声波数据进行了修正。
英文摘要：
New theoretical formulae of the sound velocity and the B/A nonlinearity parameter for some fluids are presented in the paper. Semi--ideal and van der Waals models of gas are considered and the parameters are compared to experiment data. The liquid water model for equation of state, given by Jeffery and Austin analytical equation, is considered also and modified on the basis of acoustic data .
