摘要：
Based on the nonlinear flux creep model, the V-I curves are numerically studied considering the influences of surface barrier. The influences of surface barrier to critical current of the high temperature superconductors (HTSC's) are carried out. The results show that as the strength of surface barrier increases, critical current increases. Besides, with the existence of surface barrier, history effect was found in V-I loop, which indicates that surface barrier is one of the important factors to make history effect.
