本文首次用会聚束电子衍射（CBED）测定了Al70Ni15Fe15准晶体的清空间群。合金的空间群为非中心对称的P10m2BAR。该合金是第一个属于非中心对称空间群的准晶体，在十角形轴方向上具有0.4 nm的晶格周期，并伴有结构调制波。
Clear space group determination of a decagonal quasicrystal has been performed for the first time by convergent-beam electron diffraction (CBED) about Al70Ni15Fe15. The space group of the alloy has been revealed to be noncentrosymmetric P10m2BAR. The alloy is the first quasicrystal to belong to a noncentrosymmetric space group, and has been found to have a lattice period of 0.4 nm in the direction of the decagonal axis, and to accompany structural modulation waves.
