Coefficient of thermal conductivity and time lag method in order to measure specific heat

摘要

(57) Abstract Amplitude of sensor output unrelated, method and the device which offer the coefficient of thermal conductivity, thermomigration ratio of the particular fluid, and more direct method in order to decide specific heat. As for this, one between the input AC signal and the output AC signal which are selected or measuring plural variable phases or time lag, it is desirable to be achieved coefficient of thermal conductivity, by thermomigration ratio characteristic, and guiding specific heat directly from there. Therefore, this kind of guidance, the amplitude based sensor compared to, in the sensor resistant element, occasionally, namely it does not depend on the estimate impossible drift.
