چکیده انگلیسی
The thermal conductivity of solid CHF2Cl was measured at saturated vapour pressure in the interval from 80Â K to the melting temperature Tm=116K by the linear-flow method. The experimental results were recalculated to a constant density of the samples. The temperature and volume dependences of the thermal conductivity of solid CHF2Cl are described in the framework of the model, where heat is transferred by phonons and above the phonon mobility edge by “diffusive” modes, migrating randomly from site to site. The mobility edge Ï0 is found from the condition, that the phonon mean-free path, restricted by the Umklapp processes, cannot be smaller than half the phonon wavelength.
