摘要

结果表明，螺旋包覆非结晶螺旋是一种普遍的结构单元，适用于从金属到聚合物的各种结构。这种单位的非晶体对称性使得充分描述这种结构的实际构型的特征成为可能。利用理论和实验数据将金属玻璃的结构描述为紧密排列的四面体螺旋的随机排列，而不是传统的原子的随机排列。

Spiral Wrapping a Noncrystallographic Spiral: A Universal Building Unit for a Wide Range of Structures from Metals to Polymers

It is shown that a spiral wrapping a noncrystallographic spiral is a universal building unit for a wide class of structures from metals to polymers. The noncrystallographic symmetry of such a unit makes it possible to describe adequately the features of an actual configuration of such structures. Theoretical and experimental data are used to describe the structure of metallic glasses as a random packing of close-packed tetrahedral spirals instead of the traditional random packing of atoms.
