自从1928年把量子力学应用于金属理论以来,,人们关于台金中电子态特性的知识就在稳步地增长。早期的工作大多是以合金所共有的电学性质和磁学性质作为研究对象,在这方面已经积累了不少的优秀文献,能够解释一系列合金的电学现象和磁学现象。在以后的研究中,不少人曾试图将合金之间的物性上的差异用其组分原子的性质来加以解释,不过,正如Mott所指出的:“除了Jones所作的寻求电于——原子比与晶体结构间之关系的工作外,将合金的性质作为成分的函数加以计算的工作尚很少见”。因之,多年来,在合金领域内,这方面的研究成果几乎全是经验性的总结,例如Vegard的合金 Since the application of quantum mechanics to metal theory in 1928, there has been a steady increase in the knowledge about the electronic state properties in Taizin. Most of the early work is based on the common electrical and magnetic properties of alloys as the object of study, in this regard has accumulated a lot of excellent literature, to explain a series of electrical and magnetic alloy phenomenon. In subsequent studies, many have attempted to explain the differences in the physical properties of alloys by the properties of their constituent atoms, but as Mott points out, “In addition to the search for electricity by Jones, Than the work related to the relationship between the crystal structure, the work of calculating the properties of the alloy as a function of the composition is rare. ” Therefore, over the years, in the field of alloys, the research results in this area are almost all empirical conclusions, such as Vegard alloy
