我们提出的新证据支持Al72Ni20Co8十方准晶的准晶胞描述，即该固体由十重对称性的重复、重叠的十方簇柱组成。我们提出了一个原子模型，与我们之前的建议和具有十重对称团簇的替代建议相比，它对电子显微镜实验的适用性有了显着的提高。
We present new evidence supporting the quasi-unit-cell description of the Al72Ni20Co8 decagonal quasicrystal which shows that the solid is composed of repeating, overlapping decagonal cluster columns with broken tenfold symmetry. We propose an atomic model which gives a significantly improved fit to electron microscopy experiments compared to a previous proposal by us and to alternative proposals with tenfold symmetric clusters.
