介绍了一种数学上简单、物理上透明的分层描述。在大气压力下的氮-氩弧在高温下的主要分层过程被预测为与摩擦力。光谱测量的质量分数分布，这提供了实验证实这种分层效果，提出。它示出，分层可以起到增加或减少氮气的质量分数，随着温度的增加，这取决于气体的组成。
A description of demixing that is mathematically simple and physically transparent is introduced. The dominant demixing process at high temperatures in an atmospheric-pressure nitrogen-argon arc is predicted to be that associated with frictional forces. Spectroscopic measurements of the mass fraction distribution, which provide experimental confirmation of this demixing effect, are presented. It is shown that demixing can act to either increase or decrease the mass fraction of nitrogen as temperature increases, depending on the gas composition.
