The surface phonons on Ag(110)are studied in the present paper by means of the lattice dynamics and an analytic embeddedatom method(EAM). The phonon frequencies and disperse curves with surface relaxation are in good agreement with the data obtained by the helium atom scattering experiments. The polarization and localization of surface vibration are in accord with the two-dimensional symmetry in the surface. The S2 and S3 surface modes along-direction are predicted, which are in agreement with the helium atom scattering experiments.
