Description	Historical development of methods and theoretical basis of differential thermal analysis (DTA) are outlined. The measured difference Delta T is not directly proportional to the rate of the process (d alpha/dt) but includes also the effect of heat inertia proportional to the slope d Delta T/dt as it was derived and incorporated into DTA equation by Vold (Anal Chem 21:683-688, 1949), Borchardt and Daniels (J Am Chem Soc 79:41-46, 1957), and suggested to be corrected in the authors' previous papers (1976). DTA experiments with rectangular pulses realized by micro-heater inside the sample show that the correction of DTA signal employing calculated heat inertia term of the DTA equation is reliable but not yet fully sufficient. It was a reason to derive a more complete DTA equation including a term expressing the changes in the temperature field inside the sample during process.. Itemized 150 references with titles.
