通过研究硬球的非胶体单分散和双分散浓悬浮液的粘度，研究了从流体到固体的转变。引入了类似于玻璃化转变密度的一系列流动性极限的概念。这个范围的下限确定和比较干燥的随机紧密包装的领域。的随机紧密堆积分数的bidisperse悬浮液的下限流动性的比率被发现是相同的单分散球，常数为1.19，这表明在此限制的随机结构。
The transition from a fluid to solid state is investigated by studying the viscosity of concentrated noncolloidal monodisperse and bidisperse suspensions of hard spheres. The notion of a range of fluidity limits, analogous to glass transition densities, is introduced. Lower bounds to this range are determined and compared with dry random close packings of the spheres. The ratio of the random-close-packing fraction to the lower bound fluidity limit of the bidisperse suspensions is found to be the same as for monodisperse spheres, a constant of 1.19, suggesting a random structure at this limit.
