Notes:
Abstract Dynamic interfacial phenomena are shown to be most satisfactorily interpreted within the general framework of the theory for system analysis. All time-dependent dilational behaviours of interfaces can be quantitatively predicted from knowledge of the dilational modulus, that is, of the transfer function of the interfacial system. The unifying mathematical formalism allows traditional experiments, known in the literature, to be connected one to another. The presented relationships are also the foundations of the transient techniques for the measurement of interfacial quantities. Problems involving diffusive surface relaxation in quiescent hydrodynamic conditions are easily analytically or numerically solved. Other complex relaxation mechanisms introduce no additional conceptual complication.
