研究了Ｓｒ、Ｎａ在ＡＩ－Ｓｉ熔体中的氧化动力学，应用原子杂化轨道理论分析了Ｓｒ、Ｎａ与ＡＩ－Ｓｉ熔体的作用机理。研究结果表明，Ｓｒ比Ｎａ具有更长的变质有效期，其原因是Ｓｒ比Ｎａ具有更加稳定的原子杂化轨道，而并非完全由工艺因素决定。
The oxidation kinetics of Sr and Na in AI-Si melt was studied. The mechanism of Sr, Na and AI-Si melt was analyzed by atomic hybrid orbital theory. The results show that Sr has a longer period of metamorphism than Na because Sr has a more stable atomic hybrid orbit than Na, and is not completely determined by the process factors.
