摘要：
The amplitude of the photoacoustic signal is measured as a function of chopping frequency for a PZT piezoelectric ceramic. Analysis of the results provide some of thermal parameters α, k and c of the PZT. Theory and experiment indicate the photoacustic method of measuring thermal parameters is possible and is a complement to the traditional methods of measuring thermal properties.
