| 摘 要： | 本文利用理想缔合液液模型，计算了１３００－１６００Ｋ温度范围内，Ａｇ－Ｌｎ（Ｌｎ＝Ｌａ，Ｃｅ，Ｇｄ）三个二元系的热力学数据；认为在液相中存在着Ａｇ３Ｌｎ和ＡｇＬｎ得缔合物，并利用浓度相互作用函数Ｓｃｃ（Ｏ）对这种短程有序性进行了讨论。

| Abstract: | Based on the ideal association solution model, the thermodynamic propertiesfor Ag-Ln(Ln=La,Ce,Gd) systems from 1300 to 1600K have been calculated. It is believedthat there exist AgLn and Ag_3Ln complexes (or associates)in the liquid phase. The short rangeordering is further discussed by using a concentration-concentration correlation functionscc(O). |
