Study of the Factors Influencing the Composition of the Mixture of Gases for Proportional Chambers.
Protvino, 2000.-p.14, figs.6, tables 7, refs.:7.


By approximating the behaviour of the gas stream propagating through an inlet with the adiabatic flow out of a hole with account for the gas compressibility, the equations have been obtained, which describe the impact of the pressure changes of initial gas components and the surrounding air temperature on the composition of a gas mixture. These relations allow one to chose an optimal set of pressures of supplying gases and to determine the admissible range of these pressures changes, which ensures the needed stability of the mixture composition, as well as selection of the suitable pressure regulators.
