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压力系数表达式．由此计算出的二元有机混合液的声速压力系数值与实验值符合较好．d on Jacobson's molecular free length theory in lipuids and the relationstip between the ultrasonic velocity and the molecular free length in organic liquids, the equation of pressure coefficient of ultrasonic velocity in organic liquid binary mixtures is derived. The calculated pressure coefficients of ultrasonic velocity are in good agreement with the measured results. PACC: 4325; 4335
