混合液体介质的特性声阻抗

Characteristic impedance of a liquid mixture

本文从理想混合液的基本假设出发，由声速公式导出了混合液的特性声阻抗表达式。在此基础上对二元混合液的特性声阻抗进行了讨论。对甘油和乙醇，进行了混合实验，由本文导出的公式所计算出的混合液的特性声阻抗值与由实验所测得的值符合较好。

The characteristic impedance of the mixture of ideal liquid is computed. The characteristic impedance of binary liquid mixture is further analysed, for the derivation of the inverse values. For glycerine mix with alcohol, the computed impedance agrees with the experimented.
