Description

где в - количество внутренней энергии де|формируемо1го образца в -момент измерени , кал.where in is the amount of the internal energy of the deformed sample at the time of measurement, cal.

Врем  установлени  заданного состо ни  чувствительного элемента отсчитываетс  с .момента подключени  питани  к мостовой схеме ключом 4, содержащей термосонроти.вление - Платиновую спираль (чувствительный элемент ), расноложенную в исследуемом образце . Термосонротивление 2 располагаетс  р дом в камере и служит дл  температурной компенсации.The time required to establish a given state of the sensitive element is measured from the moment when the power is connected to the bridge circuit by key 4, which contains thermal monotony. The effect is the Platinum coil (sensitive element) located in the sample under study. Thermal resistance 2 is located adjacent to the chamber and is used for temperature compensation.
