摘要: Abstract The calibration functions of amplitude and phase lag the dynamic heat-flow rate temperature-modulated DSC are investigated by model calculations. results experimentally verified for sapphire polystyrene. depend on sample as well heat-transport conditions holder. At low frequencies, these constant. However, in entire frequency range, knowledge is necessary. dependence investigated. determined actual heat-transfer parameter. Using presented model, this parameter can be evaluated from phase-lag information used calibration.
