载热 meaning in English

heat-carrying
◇载热体 heat-carrying agent

And non - fourier heat conduction is encountered . when the wavelength of the heat carrier is comparable to the characteristic length of the structures , or the time of heat conduction is shorter than that required for reaching the state of thermal equilibrium , the heat conduction has wave characteristics
当载热体的微时间尺度与能量激发特征时间相比拟时,或者传热发生的时间比达到热力学平衡态所需的时间短时,热传导就可能出现波动性质。
