Abstract
Entropy of lattice gas model used for description of equilibrium vertical density profile in granular materials subjected to gravity field. We perform the parameter (like Lindeman parameter in the theory of melting of the quantum crystals) which describe the structural deformations in considered systems. We observe good qualitative agreement between the data of theory and experimental observations, which became quantitative in the closest neighborhoods of the point of maximum compactisation.
