摘要
傅里叶定律能够精确描述大多数的热传导问题，但对于超短脉冲激光加热等热作用的周期时间极短的超急速、超常规热传导等问题，非傅里叶效应将会显得至关重要．对非傅里叶热传导的实质、模型、模型的求解及应用与实验等几个方面的研究进展做了一个较详尽的概括与评述，并指出了今后需要着重研究的方向．
Rapid transient heat conduction is an emerging area in modern high and new technologies such as ultrashort pulse laser heating, rapid solidification of metals. Under such a condition when the time scale of the heating process is extremely small, the non-Fourier effects in the heat conduction become significant. The advances in the study of mechanisms, modeling, applications and experiments in non-Fourier heat conduction are reviewed in this paper. The topics for further investigations are suggested.
