摘要
根据Jacobson的液体分子自由程理论和液体声速与分子自由程的关系 ,推导出了多元有机混合液声速压力系数与组成多元有机混合液各组分的特性参量 (声速、密度、自由程、等温压缩系数等 )之间的关系式 .利用文中给出的公式 ,对由丙酮、苯、四氯化碳、甲醇组成的三元系、四元系有机混合液声速的压力系数进行了数值预测 ,预测结果与实验测量结果符合较好 。
According to the Jacobson′s molecular free length theory in liquid and the relationship between the ultrasonic velocity and the molecular free length in organic liquid, the relationship between the parameter of every component of the mixture and the pressure coefficient of ultrasonic velocity in the mixtures made up of multi_kinds organic liquid has been derived.According to this parameter of every component (density?ultrasonic velocity?free length?the isotonic expand coefficient ?ect.),the pressure coefficient of the ultrasonic velocity in the mixtures made up of carbon tetrachloride?benzene?acetone and methanol can be predicted. The predictived results are in good agreement with the experiment results and also the pressure coefficient of the ultrasonic velocity is positive number.
