kn-abstract=<p>Recent ideas about the analog for a three-phase contact line of the Gibbs adsorption equation for interfaces are illustrated in a mean-field density-functional model.  With $d¥tau$ the infinitesimal change in the line tension $¥tau$ that accompanies the infinitesimal changes $d¥mu_i$ in the thermodynamic field variables $¥mu_i$ and with $¥Lambda_i$ the line adsorptions, the sum $d¥tau + ¥Sigma ¥Lambda_i d¥mu_i$, unlike its surface analog, 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.</p>
