【 摘 要 】

In this paper we consider fundamental, and one of the most interesting questions that arise in the theory and practice of two-temperature arc matter of breaking Te(R) and atomic-ion (gas) T(R) temperatures on the border of the electric arc. For the two-temperature calculations used channel model arc. Presented gap value calculated for different values of the current strength in the discharge. Calculations were made for an argon plasma at atmospheric pressure for two values of current intensity I = 78 A, and I = 200 A and various values of the wall temperature. Also shows the corresponding experimental results for the same conditions of other authors, we are in good qualitative agreement of the results of calculations with experimental data.
