摘要：

We presented a study of advantages and limitations of different temperature-time profiles for simultaneous multi-frequency TMDSC measurements. Theoretical consideration was followed by some experimental examples. We showed that the optimal program temperature should contain sharp steps. In experiments higher harmonics of heat flow rate up to 100th were detected which means simultaneous covering two decades of frequency in a single measurement. Importance of linear conditions was also discussed and the way to check linearity was shown. (C) 2001 Elsevier Science B.V. All rights reserved.
