Furthermore, the metallic glass samples are prepared by vacuum injection method and the rationality of above-mentioned relationships and RBF models is directly verified. It is shown that there are extremum phenomena between the Rc andΔd ,Δe and v respectively. However, the positions of the extremum are different from different alloy systems and the extremum phenomena may be related to the optimum composition region and the optimum additive quantity. More elements in the alloy are in favor of the improvement of the GFA. And as for the high GFA alloy, the atomic percentage, atomic radius difference and atomic electronegativity difference are harmoniously matched.

d、Δe和v与临界冷却速度Rc的关系中都出现极值现象，对于不同的合金体系，极值出现的位置不同；金属玻璃的最优成分范围以及各种添加元素的最佳添加量行为，可能与此极值现象相关；合金中包含的组元数目多有利于提高其玻璃形成能力，玻璃形成能力强的合金，其各个组元的原子百分含量、组元原子半径差及其电负性差之间的搭配是很和谐的；融合建模的合金系之间包含的主要组元数量和种类越相近，所建立的模型的可靠程度越高，其预测结果与实测结果越吻合。
