本文以SDM_(-R)中的各物理参量为基点,描述镧系元素的“四素组”效应,讨论“四素组”效应在色层分离中产生的原因及机理,将参量Δ1gI定义为分离因子;并讨论影响N值的各种因素。
This paper describes the “four-group” effect of lanthanides based on each physical parameter in SDM_ (- R) and discusses the reason and mechanism of the “four-group” effect in the chromatographic separation. The parameter Δ1gI is defined as Separation Factors; and discuss various factors that affect N values.
