我们研究了准晶中18重对称性的起源。我们进行Monte Carlo模拟的2D磁盘与硬核/方肩潜在的相互作用，我们分析了键取向顺序和本地顶点配置。我们发现，所谓的特殊的颗粒簇在三组键方向的混合中起着至关重要的作用20分开，产生18倍衍射图案。
We investigate the origin of the 18-fold symmetry in quasicrystals. We perform Monte Carlo simulations of 2D disks interacting with the hard-core/square-shoulder potential, and we analyze the bond-orientational order and the local vertex configurations. We find that the so-called special clusters of particles play a crucial role in the mixing of the three sets of bond directions 20 apart, producing the 18-fold diffraction pattern.
