Recent ideas about the analogue for a three-phase contact line of the Gibbs adsorption equation for interfaces are illustrated in a mean-field density-functional model. With d the infinitesimal change in the line tension that accompanies the infinitesimal changes di in the thermodynamic field variables i and with i the line adsorptions, the sum [image omitted], unlike its surface analogue, is not 0. An equivalent of this sum in the model system is evaluated numerically and analytically. A general line adsorption equation, which the model results illustrate, is derived.
