Due to the thermal delay of calorimeter, the measured thermoanalytical curve was distorted. A method to modify the distorted thermoanalytical curve into the real thermoanalytical curve from which the kinetic parameter can be obtained directly has been established in this paper. The theoretical equation for calorimeter, in which the delay of sensing has been considered, and the thermo-kinetic research method for faster reactions, namely the modifier method of distorted thermoanalytical curve, have been suggested. The thermo-kinetics. of a few faster reaction systems has been studied with this method and the validity of the theory and method has been verified by the experimental results.
