摘要：

The photothermal radiometry (PTR) signal is analyzed in order to simultaneously obtain the thermal diffusivity and effusivity of solid materials. Analytical procedures that allow the determination of the thermal parameters via a frequency scan of the amplitude or the phase of the PTR signal are presented. The measurement procedures do not involve a multiparameter-fit optimization algorithm. The methods have been used for the measurement of thermophysical properties of vitreous carbon and lead-itanate-zirconate ceramic samples. (c) 2005 American Institute of Physics.
