中文摘要：

理想金属玻璃是指完全满足电子结构稳定性的金属玻璃.在我们前期工作中提出的＂团簇加连接原子＂及理想金属玻璃的＂团簇-共振＂结构模型的基础上,本文指出理想金属玻璃应该满足电子化学势均衡判据,可定量给出团簇与连接原子的比例,最终确定了理想金属玻璃成分式[团簇]（连接原子）x.运用此判据,解析了Cu-Zr基和Co-B基块体金属玻璃,实验确定的最佳形成能力成分满足电子化学势均衡.

英文摘要：

Ideal metallic glasses are the metallic glasses that satisfy electronic structure stability.Previously we have developed a socalled ＇cluster-plus-glue-atom model＇ and more recently a ＇cluster-resonance model＇ for the ideal metallic glasses.Good metallic glass forming compositions always satisfy simple cluster formulas[cluster]（glue atoms）,with x denoting the number of glue atoms matching one cluster.In this paper we present an electrochemical potential equilibrium criterion based on these models to obtain the number of glue atoms.By examples of Cu-Zr and Co-B bulk metallic glasses,it is confirmed that the experimentally determined good BMG-forming compositions well agree with the calculated composition formulas.
