摘要
材料固有的性质是其应用的重要依据,主要取决于它的电子结构、原子结构和化学键结构。最基本和重要的材料结构是原子-电子结构。根据固体与分子的经验电子理论(EET),分别计算了AlY_2和AlHo_2两种化合物的价电子结构。分析价电子结构与力学性能之间的关系发现,AlY_2化合物的强度、塑性和金属性均优于AlHo_2化合物。
The inherent property of a material is an essential basis for its application, and depends mainly on its electronic, atomic and chemical bonding structures. The most basic and important material structure is an atomeleetronie structure. Based on the empirical eleetron theory （EET） of solid and molecule, the valence-electron structures of compounds such as AlY2 and AlHo2 were calculated respectively. From analysis on the relation of valenee-electron strueture to mechanieal properties it is found that the AlY2 compound is superior to the AlHo2 compound in hardness, ductility and metallicity.
