【 摘 要 】

The behavior of the H2O concentration in stainless steel chamber is compared for the cases of gas with and without plasma discharge at different temperatures of chamber wall. The experiments were performed with the use of mixtures of rare gases and water vapor. In absence of plasma discharge the dynamics of the density of the water molecules was determined by their interaction with the surface. In the presence of a gas discharge the concentration of water molecules in the volume of the chamber was determined by optical actinometry method. The role of the chamber wall temperature is discussed.
