AB_2型Laves相储氢合金相组成的PLS分析

Analyzed the Effect Factors of AB_2 Type Laves Phase Hydrogen Storage Alloys by Partial Least Square(PLS) Method

利用偏最小二乘法(PLS)研究AB2型Laves相储氢合金中C14、C15结构的影响因素,并得出了这两种结构形成的判据:AB2型Laves相储氢合金中的C14、C15结构的形成受A、B两元素的共价半径比(RA/RB),外层电子的平均浓度(ANOE),A、B两元素的电负性差Δφ这几个因素的影响。其中影响最大的因素为两元素的共价半径比(RA/RB)。

The effect factors of C14,C15 structure in AB2 type Laves phase hydrogen storage alloys are analyzed by Partial Least Square（PLS） method,and some criteria for forming of C14,C15 structure are obtained： RA/RBANOE（the Averaged Number of Outer Electrons） and Δφ have influence on forming of AB2 type Laves phase hydrogen storage alloys.RA/RB is the most important factor effecting forming of C14 and C15 structure.
