Description
теш1(И1роводом. Задача температурных змерений сводитс при этом к индикации равенства температур другой пары торцов. Это может быть осуществлено прв помощи чу 9ствительного средства регистрации без его тщательноА калибро ш. В частиостн, («робоваыо применение термоиндикат1фов плавлени . Требуемое рсвенство температур достигаетс за счет подбора тошоины K{miponbH№o обраааа . Предлагаемый способ может быть по леэев дл массовых измерений теплопро водиоств однотипш образков. Формула нзобретени Способ определени коэффициента теплопроводнос-ш с использованием исследуемого и контрольного образцов в виде цилиндров или призм равного сечени , состо щий в том, что nponycK UOT вдоль оси образцов равные тепловые потоки и поддерживают равными температуры более холодных борцов образцсю, о тличающийс тем, что, с целью повышени точности, варьируют высоту одного из образцов так, чтобы выровн ть температуры гор чих торцов образцов , а искомую величину определшот, исход из значений высот образцов и известното значени коэффициента теплопроводности контрольнсго образца.

The task of temperature measurements is reduced to indicating the equality of the temperatures of the other pair of ends. This can be accomplished using a sensitive recording tool without carefully calibrating it. Partly, (“using the melting thermal indices. The required temperature difference is achieved by The selection of the toshoins K {miponbH · o is performed. The proposed method can be used for mass measurements of heat conduction of the same type of samples. Invention Formula The method for determining the thermal conductivity coefficient using test and control samples in the form of cylinders or prisms of equal cross section, consisting in the fact that nponycK UOT along the sample axis equal heat fluxes and keep temperatures of colder wrestlers equal to the sample that, in order to increase accuracy, vary the height of one of the samples so as to equalize the temperatures of the hot ends of the samples, and the desired value is determined based on the values of the heights of the samples and the known values of the thermal conductivity of the control sample.
