我们简化了Polder和Van Hove的形式主义。[B] 4,3303(1971)]，该方法用于计算任意形状、色散和吸附介电性质的宏观和纳米尺度体之间的传热。在非迟滞极限下，在物体之间的小距离处，问题被简化为静电问题的解。我们将此公式应用于：(a)两个平行的半无限物体，(b)一个半无限物体和一个球面物体，以及(c)两个球面物体之间的传热研究。我们考虑了传热对温度T，形状和分离d的依赖。我们确定了延迟效应何时变得重要。
We simplify the formalism of Polder and Van Hove [Phys.Rev.B 4, 3303(1971)], which was developed to calculate the heat transfer between macroscopic and nanoscale bodies of arbitrary shape, dispersive and adsorptive dielectric properties. In the non-retarded limit, at small distances between the bodies, the problem is reduced to the solution of an electrostatic problem. We apply the formalism to the study of the heat transfer between: (a) two parallel semi-infinite bodies, (b) a semi-infinite body and a spherical body, and (c) that two spherical bodies. We consider the dependence of the heat transfer on the temperature T, the shape and the separation d. We determine when retardation effects become important.
