应用扩充的 Ｍｉｅｄｅｍａ合金相元胞模型，以电负性 φ、 Ｗａｇｎｅｒ－Ｓｅｉｔｚ元胞电子云密度 ｎｗｓ１／３、原子半径Ｒ、价电子数Ｚ及其函数张成多维空间，总结过渡金属元素和非过渡金属元素间二元化合物的形成规律，寻找中间化合物形成区域的数学模型．求得的数学模型可用于同类型的“未知”二元合金系化合物形成的预报，其效果比Ｍｉｅｄｅｍａ的二参数模型有较大的改善． By using the extended Miedema alloy phase cell model, the multi-dimensional space is defined by the electronegativity φ, the Wagner-Seitz cell electron cloud density nws1 / 3, the atomic radius R, the valence number Z, and its functions. Transition metal elements between the formation of binary compounds, looking for the formation of intermediate compounds mathematical model. The mathematical model obtained can be used to predict the formation of the same type of “unknown” binary alloy compounds, and its effect is greatly improved compared with the two-parameter model of Miedema.
