Une hypothèse est présentée, qui différencie lʼétalement produit par des forces hydrodynamiques de celui engendré par des effets cinétiques ou moléculaires, permettant ainsi de séparer les régimes suivant les vitesses des lignes de contact et les angles de raccordement. Ce critère est discuté dans le cas de plusieurs applications expérimentales.
A hypothesis is presented that distinguishes the characteristics of spreading by hydrodynamic forces from those driven by molecular/kinetic effects, demarking the regimes by contact-line speeds and contact angles. Several applications of the criterion to experiments are discussed.
