用非线性BGK动力学方程处理了在强蒸发和再冷凝作用下纯蒸汽在两平行平面间的分布。边界条件允许蒸发、冷凝和漫反射。相应的积分方程系统被带入一个形式，允许数值处理下降到克努森数为0.1。对于两种特殊情况，给出了通量率以及密度和温度分布。在以可达到的最大流速蒸发到无限半空间的情况下，离开表面的颗粒中约有15%被反向散射。
The distribution of pure vapor between two plane parallel surfaces under the influence of strong evaporation and recondensation is treated by the nonlinear BGK kinetic equation. The boundary conditions allow for evaporation, condensation, and diffuse reflection. The corresponding system of integral equations is brought into a form that allows numerical treatment down to a Knudsen number of 0.1. For two special cases the flux rates as well as the density and temperature profiles are given. In the case of evaporation into an infinite half‐space at the maximum attainable flow rate about 15% of the particles leaving the surface are backscattered.
