A review and analysis of studies concerning the nature of Poisson's ratio ##IMG## [http://ej.iop.org/images/1063-7869/63/4/327/tex_pu_8787_img1.gif] {$ \mu$} of glassy systems are presented. The value of ##IMG## [http://ej.iop.org/images/1063-7869/63/4/327/tex_pu_8787_img1.gif] {$ \mu$} is a more pronounced structure-sensitive property than are elasticity moduli. The unique relation of ##IMG## [http://ej.iop.org/images/1063-7869/63/4/327/tex_pu_8787_img1.gif] {$ \mu$} to the Gr ##IMG## [http://ej.iop.org/images/1063-7869/63/4/327/tex_pu_8787_img2.gif] {$ \rm\ddot {u}$} neisen parameter is substantiated. In this connection, the interrelation of harmonic (linear) and anharmonic (nonlinear) characteristics is discussed. Poisson's ratio is a single-valued function of parameters characterizing dynamic properties and critical processes and is sensitive to the lattice dynamics and the atomic-...
