摘要:

We present a new order metric for tetrahedral particle packing, which is observed to have a strong linear correlation with the packing density. We propose the concept of quasi-random packing to represent the hierarchical random packing structure of clusters. We also find that the nematic order of clusters can be used to classify the ordered and disordered packing of tetrahedra, which is also an indicator for quasi-random packing.
