本文引入了改编自生物多样性文献的结构多样性定义，用以对凝聚态物质的结构进行通用表征。以Favored Local Structure（FLS，偏好局域结构）晶格模型为测试平台，研究发现该多样性度量可有效滤除外在噪声，并能有效区分晶体与非晶态结构。我们识别出一类介于晶体和玻璃态之间的有趣结构，其特征是短程有序与长程无序的复杂组合。我们还演示了如何将该多样性作为序参量，依据结构随多样性提升而发生的变化对各类场景进行归类。
英文摘要：
A definition of structural diversity, adapted from the biodiversity literature, is introduced to provide a general characterization of structures of condensed matter. Using the Favored Local Structure (FLS) lattice model as a testbed, the diversity measure is found to effectively filter extrinsic noise and to provide a useful differentiation between crystal and amorphous structures. We identify an interesting class of structures intermediate between crystals and glasses that are characterised by a complex combination of short-range ordering and long-range disorder. We demonstrate how the diversity can be used as an order parameter to organise various scenarios by structure change in response to increasing diversity.
