METHOD OF COMPLEX DETERMINATION OF THERMAL AND PHYSICAL CHARACTERISTICS OF SUBSTANCE

摘要

FIELD: measurement of thermal and physical parameters of substance in gaseous, liquid and solid states. SUBSTANCE: heat pulse with known quantity Q of heat is sent into examined substance and time τ_m of displacement of temperature maximum to point remote from heat source by distance τ₀ is measured. Temperature t°0of heat source is measured at moment of passage of temperature maximum of heat pulse through this point. EFFECT: increased measurement accuracy. 1 dwg
