在重要的合金相、金属化合物中有一类化合物,它们的结构主要受电子浓度因素控制,这类化合物被称为电子化合物。Hume-Rothery 研究了一系列以贵金属为基的金属化合物,发现其晶体结构与电子浓度(合金中价电子数与原子数之比)之间的规律即 Hume-Rother In the important alloy phase, a class of compounds in the metal compounds, their structure is mainly controlled by the electron concentration factors, these compounds are called electronic compounds. Hume-Rothery studied a series of noble metal-based metal compounds and found that the law between the crystal structure and electron concentration (the number of valence electrons in an alloy and the number of atoms) is Hume-Rother
