摘要：

The glassy behaviour of the thermal conductivities of structure I xenon and structure II hydrate at high temperature are found to be described surprisingly well by a localized oscillator model. This observation leads to the suggestion of strong coupling between the localized vibrations of the guest with the lattice acoustic phonons. This conjecture is confirmed by a phenomenological calculation using the Anderson-Fano resonant scattering model.
