We introduce the Olami-Feder-Christensen(OFC)model on a square lattice with some“rewired”long-range connections having the properties of small world networks.We find that our model displays the power-law behavior,and connectivity topologies are very important to model’s avalanche dynamical behaviors.Our model has some behaviorsdifferent from the OFC model on a small world network with“added”long-range connections in our previous work[LINMin,ZHAO Xiao-Wei,and CHEN Tian-Lun,Commun.Theor.Phys.(Beijing,China)41(2004)557.].
