摘要：

The classical and Boersma DTA signals produced by melting, by endothermic and by exothermic first-order reactions have been simulated using a simple model of a DTA instrument. The simulations have been related to reality by comparison with experimental results. The simulated DTA curves have been subjected to non-isothermal kinetic analysis using the Borchardt and Daniels method and the kinetic parameters derived have been compared with the input values. The consequences of the approximations used are discussed. © 1990.
