Simulation of differential scanning calorimetry and thermogravimetry for first order reaction, three dimensional nucleation growth reaction, three dimensional diffusion reaction, two dimensional phase boundary reaction and 0th order reaction were carried out under the heating rate of 0∼20K min-1 and activation energy of 5∼40kcal mol-1. Simulation curves were drawn as contour lines and perspective projections in order to clarify characteristic properties and common properties for each reaction. Methods to determine reaction mechanism and activation energy were described with the aid of the simulation curves and theoretical equations.
