| 摘 要： | 本文提出一个既具有五次旋转的20面体点群（Ih,5m3）也显示由5个共轭立方格子表征的三维平移周期性的几何构型──正12面体框架构型（RDFC）所对20面体相原子结构进行了诠释，同时也诠释了1981年发现的20面体相（Ⅰ相）的电子衍射图（EDPs）和高分辨电子显微象。

| Abstract: | This paper presents a tree-dimensional perlodlcal geometric configuration framework configuration of a posltive dodecahedron (RDFC ) which not only possesses a penta-rotatlng icosa-hedral point group (Ih, 5m3), but also is marked by five conjugated cubic lattices. ln addition an interpretation is made of the atomlc structure of the icosahedron, as well as of EDPs and high-res-olution electron microscoplc lmage of the icosahedral phase (phase I ) discovered in 1984. |
