Superior resistance to abrasion but also high chemicalaffinity to iron which results in being unsuitable for steel machining.
优越的耐磨性，还具有高化学亲和力正在为中铁钢材加工不当的结果。

However, the interaction energy reveals more than just chemicalaffinity. It also gives an idea of how volatile an element is, even if only one or two atoms are available.
In the field of chemistry, the origin of universe, the structure of an atom, chemicalaffinity and catalytic reaction etc. are discussed and analysed by Yuanji theory.
