稀土族Pm和Tm基上二元合金固溶度的椭圆区分法预测

PREDICTION OF SOLUBLE ELEMENTS ON Pm, Tm METALS BY USING ELLIPSE REGULARITY OF BOND-PARAMETER FUNCTION AND SIZE FACTOR

利用张邦维等提出的键参数函数y=(z/r_k)·[x_p-1/3(z/r?+2)]·x_p和尺寸因素x=R方法对稀土族Pm、Tm两元素基上的室温下固溶度做椭圆(x-m)~2/c^2+(y-n)~2/d^2=1预测,从该方法对23个过渡族基、18个简单元素基、13个稀土族元系基和3个锕系元素基上的二元合金固溶度的研究结果和已有的数据及与Villars的预测结果比较来看,本文的预测结果是可靠的。

In this paper, the ellipse regularity of bond-parameter function and sizefactor are used to study the soluble elements on the Pm and Tm host metals.The results show that the predicting soluble and insoluble elements, the para-meters for determining the ellipse regularity in, n, c and d are comparable withthe experimental data and the results obtained by Villars, which implies thatthis prediction is realible.
