(a) The dependence between coverage ρ and particle number N . The solid lines are the linear fits to the simulation data, where γ = 0, t = 30. (b) The behavior of the slope k as a function of l with t = 30. The solid and dash lines are the fits to the simulation results with γ = 0 and γ = 0.5, respectively.
