【 摘 要 】

The true activation energy has been obtained by the trend extrapolation under the differential condition. The frequency factor and the reaction model can be uniquely determined by comparing the result of the model-fitting method with the true activation energy. The result is shown that, the true activation energy can be used to determine the kinetics parameters for the decomposition reaction of calcium carbonate under non-isothermal conditions.
