【摘要】 第30届中国化学奥林匹克竞赛(决赛)理论试题6-6的答案解析在已公开发表的刊物和书籍中存在差异，但其原因尚未得到充分解释。为了更深入地解析这个问题，采用了简化的二维密置层模型来计算表面金属断键的数量。在此基础上，对试题进行了全面的剖析，并对相关的晶体结构知识进行了深入探讨。这项研究不仅有助于加深我们对表面知识的理解，同时也有助于推动结构化学的分层教学。更多还原

【Abstract】 The answers to question 6-6 of the 30th Chinese Chemistry Olympiad(Final) vary in published journals and books, but the reasons for this have not been fully explained. To analyze this problem in more depth, a simplified 2D dense layer model is used to calculate the number of metal broken bonds on the surface. Based on this, this paper conducted a comprehensive analysis of the test questions and had an in-depth discussion on the relevant crystal structure knowledge. This research not only helps to deepen our understanding of surface knowledge, but also promotes hierarchical teaching of structural chemistry.更多还原
