Description

мен етс  во времени линейно. Измер ют температуру поверхности по термо-эдс термопары, расположенной на поверхности образца. Регистрируют изменение термо-эдс всех термопар в процессе нагрева и определ ют врем  достижени  каждой из термопар одной и той же относительной температуры, равной отношению температуры спа  к температуре поверхности . Глубину заделки рабочего спа  одной из термопар (X«) наход т по формулеvaries linearly with time. The surface temperature is measured by the thermo-emf of a thermocouple located on the surface of the sample. The change in the thermopower of all thermocouples during heating is recorded and the time it takes for each thermocouple to reach the same relative temperature, equal to the ratio of the temperature of the spa to the surface temperature, is determined. The embedment depth of the working spa of one of the thermocouples (X ") is found by the formula

V tjc/to , V tjc / to,

где t,5 - врем  достижени  относительной температуры термопар.ой, глубина заделки которой  вл етс  искомой величиной;where t, 5 is the time to reach the relative temperature of the thermocouple, the depth of embedding of which is the desired quantity;

t, -врем  достижени  относительной температуры термопарой, глубина заделки которой определ етс  измерительным инструментом .t is the time the relative temperature is reached by the thermocouple, the depth of embedding is determined by the measuring instrument.

Предложенный способ нар ду с повышени ем точности измерени  позвол ет .сократить продолжительность эксперимента и существенно упростить его.The proposed method, together with an increase in measurement accuracy, makes it possible to shorten the duration of the experiment and simplify it significantly.
