在本文中，我们讨论了气体蒸发冷凝室中钠蒸气的冷凝和钠气溶胶的形成。采用描述蒸汽传输到蒸汽/气溶胶界面的一维模型来确定开始过饱和度，其中我们假设观察到的界面位置与成核率最大值一致。然后，我们在基于液滴模型的成核理论背景下展示并讨论了所得的成核起始过饱和数据。成核结果似乎与在热扩散云室中进行的铯汽液成核研究一致。
In this paper we discuss the condensation of sodium vapor and the formation of a sodium aerosol as it occurs in a gas evaporation condensation chamber. A one-dimensional model describing the vapor transport to the vapor/aerosol interface was employed to determine the onset supersaturation, in which we assume the observed location of the interface is coincident with a nucleation rate maximum. We then present and discuss the resulting nucleation onset supersaturation data within the context of nucleation theory based on the liquid droplet model. Nucleation results appear to be consistent with a cesium vapor-to-liquid nucleation study performed in a thermal diffusion cloud chamber.
