摘要：

A survey is presented on recent progress in the understanding of the lattice dynamics in Nd2CuO4, (La,Sr)2CuO4 and YBa2Cu3O6/7. Classical anharmonicity and twinning were found to be major complications for the interpretation of the data. The lattice vibrations of the cuprates can now largely be described within the framework of shell models for strongly ionic compounds. Phonon anomalies inferred from a comparison of doped and undoped compounds resemble those found in classical superconductors.
