摘要/Abstract

摘要： 基于准晶结构的投影描述法,发展了一种准晶的切割投影图的计算方法,并将这种方法用于十次准晶。首先用计算机计算了完整十次准晶平行于准周期平面的切割投影图,然后对沿周期方向有无限长直位错的十次准晶,分别计算了仅引入相位子应变和同时引入相位子、声子应变的平行于准周期平面的切割投影图。

Abstract: Based on the cut and projection description of quasicrystals, a method for calculating section projection diagrams of quasicrystals is developed and applied to decagonal quasicrystals. Firstly, a section projection diagram parallel to the quasiperiodic plane of perfect decagonal quasicrystal is calculated. By using the existing elastic displacement field formulae, section projection diagrams parallel to the quasiperiodic plane of a decagonal quasicrystal containing a straight dislocation along periodic direction have been calculated when the phason strain and the phason phonon strain are introduced respectively.

Key words: quasicrystal, projection method, section-projection diagram
