根据高分辨电子显微镜像的观察，建立了由τ 2膨胀的单斜Al 13 Co 4近似体形成空间群为P10 m2的Al-Co十次准晶的模型.结果表明，Al-Co十次准晶的星星状和冠状结构单元是由拉长的六边形瓦片或τ 2 -Al 13 Co 4基本结构单元组合而成的。
A model for the formation of an Al-Co decagonal quasicrystal with space group \(P\overline{10}m2\) from a τ 2 -inflated monoclinic Al 13 Co 4 approximant is constructed on the basis of the observation of high-resolution electron microscope images. It is shown that star- and crown-shaped structural units of the Al-Co decagonal quasicrystal are formed by combining elongated hexagon tiles or the basic structural unit of τ 2 -Al 13 Co 4 .
