| Abstract: | The lattice vibration equations of a diatomic chain with an impurity atom and on-site potential are solved. The analytic solutions of local vibration are obtained. The basic features of the effect of on-site potential on the local vibration are given, and the existence forms of localized mode are also discussed. |

| Keywords: | impurity on-site potential localized mode |
