Al—Cu—Li生成的大块准晶结构模型的初探

A PRELIMINARY STUDY ON THE STRUCTURE MODEL OF THE BLOCKY QUASICRYSTAL OF Al-Cu-Li

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;
