摘要：

Biased diffusion in disordered media is analysed by means of the exit-time equation. Numerical results on percolation lattices show that a disordered medium behaves in the presence of a biasing field as an energy barrier whose intensity is monotonically increasing with field strength. This result is confirmed by a theoretical model.
