结果表明，单斜Al_（13）Fe_（4）、具有2nm镜面对称团簇柱的十边形Al_（72）Ni_（20）Co_（8）和具有2nm五重对称团簇柱的十边形Al_（70）Ni_（15）Fe_（15）三种结构都具有五边形柱，它们是由不同堆积顺序的原子团簇组成的。总结了两种十次准晶的结构和结构模型。讨论了它们之间的结构关系。
It has been shown that three types of structures of monoclinic Al13Fe4, decagonal Al72Ni20Co8with 2-nm mirror-symmetric cluster-column and decagonal Al70Ni15Fe15with 2-nm 5-fold-symmetric cluster-column, have pentagonal columns, which are composed of common atom-clusters with different stacking sequences. The Al13Fe4structure and structural models of the two decagonal quasicrystals are summarized. The structural relation among them is discussed.
