| 摘 要： | The creep motion in a two-dimensional fully frustrated square lattice Coulomb gas model with disorders is studied by using the Monte Carlo technique. The dependence of charge current density J on electric field E is investigated at low temperature T and at low E. The results show that the creep obeys the Arrhenius law J - C（T） exp-U（E）/T]. The prefactor C（T） increases with the temperature in a power law relation with an exponent about 3.0. The energy barrier U （ E） increases logarithmically with Ec,/ E as U （ E） - Uo ln（ Ec/ E） with Ec being the critical field at zero temperature.
