由于SIMS分析具有很高的表面检测灵敏度,可以检测超轻元素和用作同位素分析,特别是它能检测以电离态形式存在的靶材料的原子簇碎片,因而可比其它许多表面分析方法(诸如AES和XPS)更直接地提供有关这些离子碎片构型的信息.本文通过把对清洁的金属镁表面进行SIMS分析的实验结果,同我们用量子化学从头计算法对镁的某些原子簇离子的稳定性计算结果相比较,从实验和理论两方面探讨了金属镁在熔盐中的化学结构和形成原因,为熔盐-液体金属的相互溶解作用提供了有参考价值的信息.
Due to the high surface detection sensitivity of SIMS analysis, ultra-light elements can be detected and used as isotope analysis, especially as it can detect cluster fragments of target material in the ionized state and thus can be more robust than many other surface analysis methods such as AES And XPS) provide more direct information about the configuration of these ion fragments.This paper presents the results of SIMS analysis of the clean magnesium metal surface with the stabilization of certain cluster ions of magnesium by quantum ab initio method Compared with the results of the calculation, the chemical structure and formation mechanism of Mg in molten salt are discussed experimentally and theoretically, which provides valuable information for the mutual dissolution of molten salt - liquid metal.
