摘要
在Jacobson液体分子自由程理论以及液体分子自由程压力系数和温度系数的基础上,研究了有机液声速压力系数及温度系数与自由程压力系数及温度系数的关系,导出了具体关系式,由此计算出的声速压力系数和温度系数值与参考值符合较好.
Baized on the Jacobson's free length theory and the pressure coefficient and temperature coefficiefit of freelength in liquids, the relationship between the pressure coefficient of ultrasonic velocity and the pressure coefficient of freelength, and the relationship between the temperature coefficient of ultrasonic velocity and the temperature coefficient offree length were studied. Exact relation equations were put forward. Calculated values by using the above equations arein agreement with the measured values.
