摘要：

A model of a disordered system containing anharmonic quasi-local modes is considered. The influence of such local anharmonism on the low-temperature heat coefficient is analyzed. It is shown that taking into account the local anharmonism results in qualitatively different T-dependences of the heat conductivity coefficient for different anharmonic parameters. The results obtained can be used in interpreting some experimental data.
