Graphic dependences for determination of temperature and electric field strength in arc discharge

The dependences of the temperature T and electric field strength E on the current I and radius R for a axisymmetric stationary equilibrium arc discharge in air, argon, carbon dioxide and hydrogen under atmospheric pressure are determined from the solution to the Elenbaas-Heller equation. The results of computations are given on diagrams in the plane lgI-R in the form of lines of constant values. The diagrams make it possible to rapidly estimate parameters of the arc discharge for the given values of I and R.
