采用激光脉冲加热及降温法测定了石墨化率不同的自焙炭块在２００—１１００℃范围内的热扩散率α．结果表明：一定温度下石墨化率越高，α值越高；石墨化率一定下，α值随温度升高而降低．文中还由实验结果讨论了自焙炭块的抗热震性指标Ｒ．
Thermal diffusivity, α, of self-baking carbon block with different graphitization degrees was determined experimentally by means of laser-pulse within temperature range of 200—1100℃. The results show that the higher is the graphitization degree of carbon blocks, the higher is thermal diffusivity, α, at a given temperature; and α is decreased with the increment of temperature at a given graphitization degree. Resistance to thermal shock, R, of the carbon blocks was discussed from the experimental results.
