摘要: Moments of frequency spectrum and Debye characteristic frequencies are taken from literature or calculated, using the data specific heat, temperatures, mean square atomic displacements fourth group elements compounds with sphalerite structure. The typical features these substances shown discussed. results some theoretical experimental determinations latticce dynamical properties compared estimated by means dependene on order moments spectrum.
