摘要：

A mathematical model has been developed in order to study the effects of sample and block parameters on the transfer of heat in a DTA apparatus. The model is used to investigate the effect of differing sample radius and physical properties on the area, shape, and peak temperature of a typical DTA peak. In this paper, it is assumed that the block has an infinite conductivity and the periphery of the sample is heated so as to rise in temperature at a linear rate. The influence of heat leakage along the thermocouple wires is also studied. © 1969, American Chemical Society. All rights reserved.
