This work presents the results of determining the temperature of plasma electrons formed in conditions of hydrodynamic luminescence – the light emission of a fluid during a flow in a narrow dielectric channel. Argon was added to the water-air mixture to measure the electron temperature of the medium, and the analysis of temperature was provided by measuring the intensity of argon lines.

The obtained data on the population of excited levels of argon is interpreted in terms of various theoretical notions. The cause of the abnormal population of 3s²3p⁵(²P^o_1/2)4p argon levels in argon-hydrogen plasma is discussed.

水的水动力发光过程中发光介质中的非平衡条件

这项工作提出了确定在流体动力发光条件下形成的等离子电子温度的结果，流体动力发光是在狭窄的介电通道中流动期间流体的发光。将氩添加到水-空气混合物中以测量介质的电子温度，并且通过测量氩线的强度来提供温度分析。

根据各种理论概念来解释所获得的氩气激发能级的数据。讨论了氩氢等离子体中3s ² 3p ⁵（² P ^o _1/2）4p氩气浓度异常的原因。
