摘要：
Using a dynamical equation we study the voltage-current characteristics of high-T(c) superconductors below the critical temperature T(c) due to thermally assisted vortex motion in a sinusoidal pinning potential, which is a good approximation to the intrinsic pinning caused by the layered structure when the magnetic field is parallel to the layers. The power-law I-V characteristics and continuous crossover from flux creep to flux flow in high-T(c) superconductors can be interpreted in a natural way.
