摘要
采用自由体积理论和Ｍｉｅｄｅｍａ生成热模型，导出了液态合金中溶质元素的ｌｎｒｉ０的计算公式；计算了１２７３Ｋ下铜液中溶质元素的ｌｎｒｉ０。结果表明，计算值和实验值的正负号一致率为９０％，并基本处于同一数量级。
The calculation formula of ln r i 0 for a solute element i in a liquid alloy was derived by use of free volume theory and Miedema formation enthalpy model. The values of ln r i 0 of solute elements in liquid copper at 1273 K were obtained. The results showed that the coincidence rate of sign (positive or negative) is 90% for calculation and experimental values which are basically in the same magnitude.
