dc.description.abstract In the article are given results of studies of laser photoacoustic for determination of the thermophysical properties of materials by the microphone detection circuits. It has been shown that the photoacoustic method for determining the thermophysical properties of materials, complementing other existing methods. The characteristic features of the application of the photoacoustic method based on the Rosencweig-Gersho fundamental theory are considered. The mathematical model of the problem for determining the thermal diffusivity of solid-state materials in one-dimensional and three-layer photoacoustic cell is developed. The proposed photoacoustic method can be successfully applied to the study of materials that are complex in structure, such as structurally inhomogeneous, multilayer, composite, powdery, nanomaterials, etc. ru_RU
