摘要：

To avoid thermostatting effort in a calorimeter the influence of ambient temperature perturbations on the output signal can be reduced by predicting and correcting the perturbation part of the output signal of the calorimeter. The prediction can be verified by measuring the temperature perturbations and simulating the corresponding output signal. Using a dynamical model of the calorimeter, simple methods for the solution of this problem are shown and tested experimentally. (C) 1997 Elsevier Science B.V.
