Annotation Based on the proposed mathematical model the mechano-electric characteristics of the near-surface layer of solids included in the linear equation of state and connecting the parameters of states were calculated. Quasiequilibrium condition model of conduction electrons (related charges) on electric double layer on the surface of solid were presented. For the first time, the most important physical quantities to the surface – surface and interfacial charge Ω, the electrical component of the surface energy e, the thickness of the surface layer h, electric double layer capacitance C and Galvani potential  for a number of materials: Cr, W, Gd, Hf, Pd, Mg, Ta, Sm, Si, Cu were calculated. These parameters for the diagnosis of structural elements in aggressive environments can be used and energy characteristics of surface and interfacial layers can be determinated.
