准晶态被认为是介于玻璃态和结晶态之间的一种新物态,具有分数维结构.本文计算了国内外提出的三种理想准晶态结构模型的分数维数;介绍了一种计算准晶态结构模型的分数维数的方法;从分数维观点对三种模型进行初步比较;指出对具有同一点群对称性的准晶态结构模型,分数维数是描述它们的特征的一个定量参数. The quasicrystal is considered as a new state between the glassy state and the crystalline state, and has a fractal structure.This paper calculates the fractional numbers of the three ideal quasicrystal structure models proposed at home and abroad, and introduces a A method of calculating the fractional dimension of a quasicrystalline structure model; preliminary comparison of the three models from the viewpoint of fractal dimension; pointing out that quasi-crystalline structure models with the same point group symmetry are pointed out, A quantitative parameter.
