A microscopic deviation is given of the boundary conditions at a specular superconductor-vacuum (dielectric) boundary for the Ginzburg-Landau equations in superconductors with anisotropic pairing. Calculations were performed for a hexagonal crystal. The form of the boundary conditions in this case depends strongly on the orientation of the surface relative to the principal axes of the crystal lattice. The equations determining the dependence of the surface-superconductivity field for different types of order parameters are derived. The applicability of the results obtained to the identification of superconducting phases in UPt{sub 3} is discussed. 20 refs., 2 figs., 2 tabs.
