A model is presented that examines the impact of local clustering upon the percolation behaviour of interpenetrable rod-like particles. The percolation threshold, as well as percolation and backbone probabilities, are evaluated as functions of the particle aspect ratio and degree of clustering by way of an analogy to a lattice site percolation problem. The formation of local, physically connected cliques of particles is shown to raise the percolation threshold whilst reducing the percolation and backbone fractions for a fixed volume fraction of particles.
提出了一个模型，研究了局部聚集对不可穿透棒状粒子渗透行为的影响。通过与晶格位渗透问题的类比，评估了渗透阈值以及渗透和骨干概率作为粒子纵横比和聚集度的函数。结果表明，形成局部的、物理上连接的粒子团簇会提高渗透阈值，同时降低固定粒子体积分数下的渗透和骨干分数。
