摘要：
A technique is demonstrated to determine thermal effusivity of solids using a photoacoustic scanning method. The technique involves changing the backing medium for a highly absorbing sample layer by scanning its surface with an intensity modulated Light beam. The method is free of photoacoustic cell parameters as well as experimental conditions and is demonstrated to give good results. (C) 1996 American Institute of Physics.
