摘　　要：依据 Ｊａｃｏｂｓｏｎ 液体分子自由程理论及液体声速与分子自由程关系，推导出二元有机混合液的声速温度系数表达式．由此计算出的二元有机混合液的声速温度系数值与实验值符合较好．Based on Jacobson's molecular free length theory in lipuids and the relationship between the ultrasonic velocity and the molecular free length in organic lipuids, the eqution of temperature coefficient of ultrasonic velocity in organic liquid binary mixtures is derived. The calculated temperature coefficients of ultrasonic velocity are in good agreement with the measured results. PACC: 4325; 4335
