摘要： In order to measure specific heat, the measurement time is very long and the instrument is very expensive. The specific heat may be calculated based on the thermal time constant obtained from the change of the sample temperature when the predetermined amount of sample with known density at the first temperature is introduced in the environment at the second temperature. This measuring method can use the oscillatory densitometer. The predetermined amount corresponds to the volume of the sample to be introduced in the oscillatory densitometer, the density is a measurement result of the oscillatory densitometer, and the thermal time constant corresponds to the time constant of the oscillation period of the oscillatory densitometer.

摘要： In a method of measuring a viscosity of a sample based on a rotation frequency ΩS of a conductive rotator rotating by applying a rotating magnetic field from outside to the rotator set in a container containing the sample and a rotation frequency ΩB of the magnetic field, a constant k1 having temperature dependency of an apparatus and a constant k2 not having the temperature dependency at each temperature are found by using a equation, η0Ωs=k1(ΩB−ΩS)−k2, where a viscosity η0 at specific temperature is known, and then a value of viscosity measured at the specific temperature is corrected by means of the constants k1 and k2, the rotation frequency ΩS of the rotator, and the rotation frequency ΩB of the magnetic field. The constant k1 may employ the temperature dependency of electric conductivity of metal used to the rotator.
