Resumen:
A macroscopic evolution equation for the roughness is presented for a growing interface in quenched disorder media for the Tang and Leschhorn model [Phys. Rev. A 45, R8309 (1992)]. We work only at the critical pressure, because we show that the power-law behavior does not hold apart from this value. Theoretical results are compared with the Monte Carlo simulation. The dynamical exponent is analytically obtained in a simple way.
