室温下的Guyer-Krumhansl型导热
Guyer-Krumhansl-type heat conduction at room temperature
摘要：
本文报道了在各种人造和天然材料中进行的热脉冲实验结果。实验在室温下用宏观样品进行。结果表明，温度的演变不遵循傅立叶定律，但很好地解释了Guyer-Krumhansl方程。观察证实了非平衡态热力学的能力，制定普遍的热机械过程的本构关系。
英文摘要：
Results of heat pulse experiments in various artificial and natural materials are reported in the paper. The experiments are performed at room temperature with macroscopic samples. It is shown that temperature evolution does not follow the Fourier's law but well explained by the Guyer-Krumhansl equation. The observations confirm the ability of non-equilibrium thermodynamics to formulate universal constitutive relations for thermomechanical processes.
