摘要：

Current-driven dynamics of vortices in Josephson junction networks under a magnetic field is studied numerically. In the presence of structural disorder in Josephson junction networks, it is found that there are two kinds of mechanisms of plastic or elastic depinning of vortices, and then the depinning critical current follows a scaling relation.
