研究了真空间隙中的辐射热输运问题。通过始终只应用物理学的基本定律，我们得到了一个代数方程，它将半空间的温度和它们之间的热通量联系起来。由该方程产生的这种结构的热传输系数与纳米级和更大间隙的可用实验数据相匹配，而不需要任何额外的特定能量传递机制。(C)2014 AIP Publishing LLC.
Radiation heat transport across a vacuum gap between two half-spaces is studied. By consistently applying only the fundamental laws of physics, we obtain an algebraic equation that connects the temperatures of the half-spaces and the heat flux between them. The heat transport coefficient generated by this equation for such structures matches available experimental data for nanoscale and larger gaps without appealing to any additional specific mechanisms of energy transfer.
