摘　　要：给出了理想二元混合液自由程压力系数与温度系数的表达式.结果表明,理想二元混合液的自由程压力系数与温度系数均为组分自由程压力系数和温度系数的线性函数,其系数为组分的自由程分数.由各组分的压缩系数、膨胀系数、绝对零度时的摩尔体积和组分分数,可以求得混合液的自由程压力系数和温度系数.The expression of the pressure coefficient and temperature coefficient of the free length in liquid binary mixtures is obtained. The pressure coefficient and temperature coefficient of the free length are linear function on components. Using the expression, the pressure coefficient and temperature of the free length in liquid binary mixtures can be calculated through the compressibility coefficients, the bulk coefficients of expansion, the molar volumes at absolute zero and weight fractions of two components.
