摘　　要：对稀土气态配合物ＬｎＡｌ３Ｃｌ１２的稳定性进行线性分析，发现其稳定常数的对数值，与镧系离子势（Ｚ＋／ｒ）之间存在线性关系，将镧系稀土分为两组，Ｌａ－Ｇｄ和Ｔｂ－Ｌｕ；与镧系离子基态角量子数存在斜Ｗ效应，将镧系稀土分为四组，Ｌａ－Ｎｄ，Ｐｍ－Ｇｄ，Ｔｂ－Ｈｏ，Ｅｒ－Ｌｕ。在每一组内。Linear analysis was carried out on the stability of rare earth vapor complexes LnAl 3Cl 12 .It is found that the values of lgK p change linearly with the ionpotentials (Z +/r) of lanthanide(Ⅲ),and that lanthanide elements are divided into two sub-group,La-Gd and Tb-Lu.It is also found that there exist inclined W effect between lgK p and the total angular momentum (L) of lanthanide(Ⅲ),and hereby lanthanide elements are divided into four segments,La-Nd,Pm-Gd,Tb-Ho and Er-Lu.In each segment,the linearity is maintained.
