The correct analysis of heat transport at nanoscale is one of the main reasons of new developments in physics and nonequilibrium thermodynamic theories beyond the classical Fourier law. In this paper, we provide a two-temperature model which allows to describe the different regimes which electrons and phonons can undergo in the heat transfer phenomenon. The physical admissibility of that model is showed in view of second law of thermodynamics. The above model is applied to study the propagation of heat waves in order to point out the special role played by nonlocal and nonlinear effects.

双温度模型中双曲热传递的非局部和非线性效应

纳米尺度传热的正确分析是超越经典傅立叶定律的物理学和非平衡热力学理论新发展的主要原因之一。在本文中，我们提供了一个两个温度模型，该模型可以描述电子和声子在传热现象中可能经历的不同状态。鉴于热力学第二定律，表明了该模型的物理可容许性。上述模型用于研究热波的传播，以指出非局部和非线性效应所起的特殊作用。
