标题： Exact results in modeling planetary atmospheres--I. Gray atmospheres

摘要： 提出了一种精确模型，用于描述处于辐射平衡的灰色、各向同性散射的行星大气。该平板的一侧被一束平行光照射，另一侧由一个发射且部分反射的地表所限制。我们给出了两个边界面上的入射和反射通量的表达式，以及地表温度和大气中温度分布的表达式，假设后者处于局部热动平衡状态。文中包含了不同光学厚度下温度分布的表格和曲线图。最后，将讨论从外部或由无限远处光源照射的半无限大气的情况。 显示英文摘要

摘要： An exact model is proposed for a gray, isotropically scattering planetary atmosphere in radiative equilibrium. The slab is illuminated on one side by a collimated beam and is bounded on the other side by an emitting and partially reflecting ground. We provide expressions for the incident and reflected fluxes on both boundary surfaces, as well as the temperature of the ground and the temperature distribution in the atmosphere, assuming the latter to be in local thermodynamic equilibrium. Tables and curves of the temperature distribution are included for various values of the optical thickness. Finally, semi-infinite atmospheres illuminated from the outside or by sources at infinity will be dealt with.
