【摘要】 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.更多还原

【Abstract】 Quasicrystal is considered as a new material state between glass and crystal with a fractal structure. This paper introduces a method of computing the fractal of a quasicrystal structure model, calculates the fractal dimensions of three ideal quasicrystal structure models set up at home and abroad, and makes a preliminary comparison among them in terms of fractal, which is a quasicrystal parameter describing the characteristics of a quasicrystal structure model with the same point group symmetry.更多还原
