摘要：
Percolation process is studied in a model granular system on a square lattice, where grains are grown around seeds up to the n-th neighbors. Critical percolation coverage Ts shown to oscillate as a function of n. The coverage at which the number of particles on the surface of clusters takes a maximum is also shown to oscillate as a function of n. These oscillations are due to the projections of grains. The percolation process is shown to belong to the universality class of two dimensional percolation.
