摘要：

Thermal diffusivity measurements of anthracene crystals are reported in the temperature range 90 to 300 K. The results are obtained by multi-frequency rear surface excitation combined with impulse response determination using correlation photoacoustic spectroscopy techniques. We describe a simple computer-based system which generates excitation waveforms and acquires as well as analyses experimental data. A one-dimensional model is proposed in order to explain the experimental results.
