摘　　要：原子团簇介于原子分子和宏观凝聚物质之间 ,一般产生于非平衡条件 ,其结构和性质随所含原子数目而变化。当含有某些特定原子数时 ,团簇特别稳定 ,这就是“幻数”。本文重点讨论几种典型团簇的幻数及其演变规律 ,说明“幻数”Atomic clusters are the intermediates between atoms and molecules on the one hand, and the condensed matter on the other, and are produced generally in non equilibrium condition. Their structures and properties change as number of atoms varies. The clusters are particularly stable when they contain certain number series of atoms. These series of numbers are called as magic numbers. In this paper we shall discuss magic numbers for several kinds of clusters and their evolution, demonstrating that magic numbers are one of the essential properties of the clusters and are related to the bonding between atoms in the clusters.
