Abstract

Abstract:

A new chemical method to calibrate the instrument constants of conduction calorimeter, including the cooling constant a of thermal system and the cooling constant β of thermal element which are related with thermal conductivity of the thermal system, has been proposed on the basis of the single parameter or double parameters theoretical model of conduction calorimeter and thermokinetic equation of chemical reaction. This method has been applied to calibrate RD496 II microcalorimeter，and a significant result has been obtained.

Key words: Thermokinetics, Conduction calorimeter, Instrument constant
