摘要：
A pulsed technique for measuring the thermal diffusivity a and thermal conductivity lambda of spherical samples with an allowance for the spatial-time energy distribution over the laser-beam cross section is described. The measured temperature dependences a(T) and lambda(T) for solid and liquid tin near the melting point of samples are presented. The a and lambda measurement accuracies are 5 and 15%, respectively.
