Thermodynamics course tells the mixing volume change.This paper studies the relationship among mixing volume change,the percentage of alcohol and taste.After fitting the experimental data to the equation,we have obtained the maximal decreased volume while the percentage of alcohol is 57°.This is the reason why the major brands of the Chinese liquor＇s percentage of alcohol are between 53° and 60°.%热力学课程讲授了混合体积变化这个热力学量。本文利用热力学知识探讨了混合体积缩小量与酒度、口感之间的关系。研究发现,在酒度为57°时,混合体积缩小量达到最大,口感最佳,这也是中国知名高度白酒酒度集中在53°~60°范围内的原因。
