SPECIFIC HEAT MEASUREMENT APPARATUS AND SPECIFIC HEAT MEASUREMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a new specific heat measurement method.;SOLUTION: A specific heat measurement apparatus includes a heat bath 10, a heat transfer unit 20, a heater 30, a control unit 40, and a specific heat calculation unit 50. The heat bath 10 is held at a fixed temperature and the heat capacity of the heat bath 10 is sufficiently larger than the heat capacity of a sample 100. The heat bath 10 is a metal ingot such as a copper ingot. The heat transfer unit 20 thermally connects the heat bath 10 to the sample 100. The heater 30 applies heat to the sample 100. The control unit 40 controls input to the heater 30. The specific heat calculation unit 50 calculates the specific heat of the sample 100 based on a change in a temperature difference between the sample 100 and the heat bath 10 or a temperature change of the sample 100. The control unit 40 alternately inputs first electric power to be a fixed value and second electric power to be a fixed value different from the first electric power to the heater 30.;COPYRIGHT: (C)2013,JPO&INPIT
