中文摘要：

We study an exclusion process with multiple dynamic roadblocks.Each roadblock can move diffusively forward or backward with different rates,as well as unbind from/rebind to a free site.By Monte Carlo simulations,the two moving types are investigated in combination of roadblock number.The case of only diffusive roadblocks shows an asymmetric current-density relation.The case of only long-range jumping roadblocks presents that flux decreases with increasing roadblock number.
