摘要：

General results on the operation of heat-flux calorimeters are obtained from a hereditary integral formulation of the calorimeter response. The behaviors of heat-flux calorimeters at long time intervals after a thermal event are examined using final value theorems of Laplace transforms. Experimental confirmation of the resulting predictions suggests an analytic procedure for desmearing or inverting calorimeter signals without the need for specific models or computer numerical techniques. Particular solutions are obtained for instantaneous heat and heat flow corresponding to an apparatus function of interest in the practice of heat-flux calorimetry. © 1990.
