Calculations of the optical and UV emission-line intensities and column densities of ions observable in the optical and UV are presented for plane-parallel, steady-state shock waves in the interstellar medium. The range of shock velocities considered is 50 km s/sup -1/ < or =..nu../sub s/< or =200 km s/sup -1/, and preshock densities are 1 cm/sup -3/ < or =n/sub 0/< or =300 cm/sup -3/. The ionization state of the preshock gas is found to be an important parameter, and several sets of elemental abundances corresponding to various amounts of depletion onto grains are used. The results are compared with observations of the Cygnus Loop, the Vela supernova remnant, and Herbig-Haro objects.
