Analysis of photothermal displacement signal at phase transitions in solids;
固体相变时光热位移信号的分析
Theoretical expression of photothermal displacement signal of the sample was introduced under laser irradiation,and the relations between not only the phase of the signal and the thermal diffusivity,but also the phase and the modulated frequency were illustrated.
