摘要：

The fluctuations of the advancing interface observed in experiments on two-phase fluid flow in porous media are investigated using several evaluation techniques. We find that the amplitudes-eta of these fluctuations are distributed according to a power law of the form P(eta) approximately eta-(mu + 1), with mu almost-equal-to 2.7. Our results together with a recent model of anomalous roughening suggest a plausible explanation for the nonuniversal values of the exponents observed in the experiment on two-phase flow.
