METHOD OF DETERMINATION OF THERMOPHYSICAL PROPERTIES OF SOLIDS

摘要

FIELD: thermal physics. SUBSTANCE: sample in the form of rectangular parallelepiped is heated with electric current and power released under stationary heating mode over isothermal section in axial direction is measured. Temperatures on surface of parallelepiped in centers of two mutually perpendicular faces and at distance from its edge equal to radius of land of sighting of optical pyrometer are measured and thermophysical characteristics are calculated by measured parameters. EFFECT: improved authenticity of determination of thermophysical characteristics. 1 dwg, 1 tbl
