【摘要】 参数估计法是对材料的非线性导热系数k和导温系数α的快速测定方法。即在一次急速升温中,通过微机检测试样两端面温度变化及相应的热流值,应用参数估计,求得各温度下的k和α值。实验证实了该法的可行性。更多还原

【Abstract】 A new method is developed for fast measurement of the non-linear thermal conductivity k and thermal diffusivity α using parameter estimation. The parameters of k and α varying with temperature can be gained by measuring temperature and heat-flow in the course of heated sample. The method is proved to be feasible through the experiment.更多还原
