摘要：

Heat conduction in DSC and sample as well as heat transfers cause a falsification (smearing) of the measured heat flux in DSC measurements. Therefore transition phenomenons (peaks and steps) in DSC-curves are measured broader and shifted along the temperature scale. A method is shown which allows a correction of the "smeared" DSC-curves on the base of linear response in the case of badly heat conducting samples. The necessary Green's function can be received from the smeared curve without additional measurement.
