中文摘要:
      根据Jacobson理论及液体声速与分子自由程的关系,导出了多元有机混合液体声速与各组分声速之间的关系;推导出多元有机混合液体声速温度特性的预测公式,并根据组成多元有机混合液各组分特性参量(摩尔分数、密度、自由程、等压膨胀系数等),利用文中给出的多元有机混合液声速的温度特性预测公式,对由丙酮、四氯化碳、苯、甲醇组成的三元系、四元系有机混合液体的声速温度特性进行了理论值的预测,理论预测结果与实验测量结果符合较好。
英文摘要:
      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,an relationship between the parameter of every component of the mixture and the temperature coefficient of ultrasionic velocity in the mixtures made up of multi kinds organic liquid have been given out;according to this paramenter of every component (fraction of mol、density、ultrasonic velocity、free length、the isotonic compress coeffcient、ect.),the temperature coefficient of the ultrasonic velocity in the three kinds and four kinds mixtures made up of carbon tetrachloride、benzene、acetone and methanol can be predicted,the predictive results are in good agreement with the experiment results.
