PROCESS OF NONDESTRUCTIVE TEST OF THERMOPHYSICAL CHARACTERISTICS OF MATERIALS

摘要

study of materials. SUBSTANCE: two point pulse sources of heat of same power are put on heat-insulated surface of tested material. Temperature-sensitive element is placed on line of location of sources of heat. Thermophysical characteristics of material are determined by action with train of heat pulses with repetition period tau from first point source of heat, then second point source of heat starts to function in step with first source. Excessive temperatures T1 and T2 are achieved. EFFECT: increased accuracy of measurement of thermophysical characteristics of materials, decreased energy consumption. 2 dwg
