摘      要：The relaxation dynamics of the zero-range process (ZRP) has been an interesting *** this study,we set up the relationship between the ZRP and a model of traps,and investigate the slow dynamics of the ZRP in the framework of the trap *** statistical quantities such as the average rest time,the particle distribution,the two-time correlation function and the average escape time,we find that the particle interaction,especially the resulting condensation,can significantly influence the *** the stationary state,both the average rest time and the average escape time caused by the attraction among particles are obtained *** the transient state,a hierarchical nature of the aging dynamics is revealed by both simulations and scaling ***,by comparing the particle diffusion in both the transient state and the stationary state,we find that the closer the ZRP systems approach the stationary state,the more slowly the particles diffuse.
