AI中文摘要：
硅藻的硅质细胞壁（frustule）长期以来以其复杂的硅结构所具备的非凡美感、多样性和功能性吸引着科学家。然而，迄今为止，这些结构的空间组织主要通过形态、对称性和晶体学有序性来描述，不同硅藻结构之间的共同统计特性在很大程度上未被探索。我们首次通过超均匀性（hyperuniformity）视角分析硅藻的硅质细胞壁，揭示了其惊人多样性中存在的显著共性：所有被分析的属都表现出长波长密度波动受抑制的特征。具体而言，我们发现这些结构涵盖从高度有序的I类到无序的III类超均匀系统的范围。我们表明，局部有序性、空间相关性和长程波动抑制可部分独立变化，从而产生连续的多尺度结构谱。我们的多尺度方法表明，超均匀性可在有限的生物结构中被可靠表征，超出了传统渐近诊断可解析的范围。总之，这些结果证明，超均匀性提供了一个统一的统计框架，用于描述超出传统结构有序性分类的硅藻多样性。
英文摘要：
Diatom frustules have long fascinated scientists for the extraordinary beauty, diversity, and functionality of their intricate silica architectures. Yet, the spatial organization of these structures has so far been primarily described in terms of morphology, symmetry, and crystallographic order, leaving common statistical properties across distinct diatom architectures largely unexplored. By analyzing diatom frustules through the lens of hyperuniformity for the first time, we reveal a striking commonality across their remarkable diversity: all analyzed genera exhibit signatures of suppressed long-wavelength density fluctuations. Specifically, we find that these architectures range from strongly ordered Class I to disordered Class III hyperuniform systems. We show that local order, spatial correlations, and long-range fluctuation suppression can vary partially independently, giving rise to a continuous spectrum of multiscale architectures. Our multiscale approach reveals that hyperuniformity can be reliably characterized in finite biological structures, beyond what conventional asymptotic diagnostics can resolve. Together, these results prove that hyperuniformity provides a unifying statistical framework for describing diatom diversity beyond conventional classifications of structural order.
