摘要
Al-Cu-Li大块准晶的结构是各国准晶研究者们正在探索的一个难题。本文从凝聚态物理、结构化学理论出发,根据“等大正二十面体共角顶连结的准晶结构模型”的基本特点,提出了Al-Cu-Li生成的大块准晶的结构模型。简称为CPL准晶结构模型。CPL结构单元A_1与CP结构单元α_1之比为729:1。
The structure of the blocky quasicrystal of Al-Cu-Li is a difficult subject that scientists of many countries are studying. According to the theory of the condensed state physics and structural chemistry, on the basis of the fundamental characteristics of ' the quasicrystal structure model in terms of corner-connected regular icosahedra of equal size (The CP model)' the structure model of blocky quasicrystal of Al-Cu-Li has been put forward in this paper. This model is cal-led 'CPL model' for short. The ratio in sizt between the structure unit A1 of the CPL model and that a1 of the CP model is 729:1;
