The impact of particle clustering and correlation upon the percolation behavior of polydisperse cylinders with finite hard core diameter is examined within an analogy to a lattice percolation problem. Percolation thresholds and percolation and backbone probabilities are explored as functions of the degree of clustering and extent of correlation among the inter-particle contacts. The percolation threshold and volume fractions occupied by the infinite network and by the cluster backbone are shown to be quite sensitive to the formation of inter-connected cliques of particles and to the presence of correlation among particle contacts.
本文考察了具有有限硬芯直径的多分散圆柱粒子簇集和相关性对渗流行为的影响，类比于格子渗流问题。研究了渗流阈值以及粒子间接触的聚类程度和相关性对渗流和骨干概率的影响。结果表明，无限网络和簇骨干的渗流阈值和占据的体积分数对粒子间的相互连接的团簇的形成以及粒子接触之间的相关性非常敏感。
