摘要
描述了准晶结构研究状况,提出了具有5次对称性的准晶结构模型,包括正二十面体与正十二面体共轭生成的准晶结构模型和Al-Cu-Li共轭生成的大块准晶结构模型;讨论了二维准晶的基本特征、二维准晶胞选取,提出了具有8、10、12次对称性的二维准晶结构模型;探讨了纳米微粒多重分数维结构模型,分别给出了多重分数维表征值.
By summarizing the researching situation of Quasicrystals,quintic symmetry Quasicrystal structure model was put forward,including Quasicrystal conjugate structural model of Icosahedra and Dodecahedra,and blocky Quasicrystal conjugate structure model generated by Al-Cu-Li.Also,by discussing basic feature of two-dimensional Quasicrystal and the selecting of two-dimensional Quasicrystal cell,we put forward two-dimensional Quasicrystal model.And then,two-dimensional Quasicrystal model with 8-fold symmetry,10-fold symmetry,12-fold symmetry was gotten.At last,structure model of multifractional demension on nano-particles was discussed and the multifractional demension representation value was gotten.
