註釋
Linear-thermal-expansion and specific-heat measurements are made in the apparatus using the same specimen. Expansion measurements are made by directly viewing fiducial marks on a cylindrical specimen with two tele-microscopes. Specific heat measurements are made by measuring the heat input to an inner heater that is required to heat the specimen of a known mass over a measured temperature range. Thermal-conductivity measurements are made by a radical heat-flow method using a thick-walled- cylindrical specimen with an encircling graphite heater.
