通过直接比较材料在其液体、稳定晶体、非晶相晶体、取向玻璃和非晶相中的静态结构因子，实验证明了在中间长度尺度上的顺序与玻璃和液体材料衍射图案中的可辨别特征之间的关系。此外，相关的取向无序的结晶相（即，无论是动态无序的一个相晶体或淬火无序的取向玻璃），作为稳定的晶体和拓扑无序（即，无定形）固体之间的中间阶段，是证明。所研究的材料是乙醇。
The relationship between order at intermediate length scales and discernible features in the diffraction pattern of glassy and liquid materials is demonstrated experimentally by means of a direct comparison of the static structure factors of a material in its liquid, stable crystal, rotator-phase crystal, orientational glass, and amorphous phases. In addition, the relevance of orientationally disordered crystalline phases (ie, either the dynamic disorder of a rotator-phase crystal or the quenched disorder of an orientational glass), as intermediate stages between the stable crystal and the topologically disordered (ie, amorphous) solid, is evidenced. The material studied is ethyl alcohol.
