By using basic concepts of the thermodynamics of materials with internal variables (continuously distributed local damages)
and taking into account chemical transformations, we deduce a set of nonlinear equations of multicomponent diffusion and propose
conditions of mass exchange which reflect the effect of accumulated damages on the processes running on the phase boundaries.

A system of differential equations for heat and mass transfer in capillary-porous materials in a hydroscopic moisture-content
field is derived with allowance for kinetics of moisture desorption, two-phase filtration, and liquid pressure determined
by the action of surface forces. An analysis is made of the results of a computational experiment illustrating evolution of
the moisture content, temperature, and vapor pressure fields against the material characteristics and kinetic coefficient.

Based on a linear model of a moist capillary-porous material that is located in an electromagnetic microwave field, basic
relations between the measured parameters and moisture content been obtained for amplitude and resonator methods. Calculated
and experimental dependences of the attenuation of the microwave energy on moisture content and variants of application of
moisture meters of the Microradar series are presented.
