摘要：

A simple approach for the calculation of photoacoustic piezoelectric response in the case of low modulation frequencies has been proposed. The analytical expressions have been obtained for the amplitude and phase of the photoacoustic signal and their experimental verification has been carried out. The new method for the thermal diffusivity determination from the phase versus frequency characteristics has been developed. (C) 1996 American Institute of Physics.
