利用五维周期晶格在二维空间上的投影，讨论了十方准晶体中的有序结构。菱形和五角形PenRose晶格中的超晶格可以分别由简单超立方晶格和体心超立方晶格衍生而来。将超晶格与Al-Ni-Co和Al-Ni-Ru十方准晶体中观察到的有序结构进行了比较。在Al-Ni-Co和Al-Ni-Ru十方准晶体中，两种具有不同取向的五方对称原子团以确定的有序方式放置在晶格点上。
Ordered structures in decagonal quasicrystals are discussed by the projection of five-dimensional periodic lattices on two-dimensional space. Superlattices in rhombic and pentagonal Penrose lattices can be derived from simple and body-centered hypercubic lattices, respectively. The superlattices are compared with ordered structures observed in Al–Ni–Co and Al–Ni–Ru decagonal quasicrystals in which two types of atom clusters with different orientations of pentagonal symmetry are placed at lattice points in pentagonal or rhombic quasiperiodic lattices with definite ordered manners.
