Использован нетрадиционный способ, основанный на определении неравновесного параметра bi, равного отношению действительной (определенной экспериментально) заселенности энергетического уровня (ni) какого-либо элемента к заселенности этого же уровня, вычисленной из уравнения Саха (nis). На примере Ca, Mg и Be установлено ионизирующее отклонение исследуемой плазмы от равновесного состояния, когда имеет место перезаселение только низколежащих атомных уровней. Показана явная зависимость величины bi от потенциала ионизации рассматриваемого элемента. Результаты интерпретированы в свете усиления роли радиационных процессов при возбуждении спектров в ДДП.</p></abstract><trans-abstract xml:lang="en"><p>The degree and nature of the violation of local thermodynamic equilibrium (LTE) in the analytical zone of a plasma jet generated by an argon arc two-jet plasmatron (TJP) was estimated using an unconventional method based on determination of the nonequilibrium parameter bi equal to the ratio of the experimentally determined actual population of the energy level (ni) of the element to the population of the same level calculated from the Saha equation (nis). Partial ionizing deviation of plasma under study from the equilibrium state takes place only when low-lying atomic levels are overpopulated. The distinct dependence of bi on the ionization potential of the considered element (e.g., Ca, Mg, and Be) is shown. The results were interpreted in the light of the increasing role of radiation processes upon excitation of spectra in the argon arc two-jet plasmatron.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дуговой аргоновый двухструйный плазмотрон</kwd><kwd>локальное термодинамическое равновесие</kwd><kwd>радиационный распад</kwd><kwd>радиационная рекомбинация</kwd><kwd>неравновесный параметр</kwd></kwd-group><kwd-group xml:lang="en"><kwd>argon arc two-jet plasmatron</kwd><kwd>local thermodynamic equilibrium</kwd><kwd>radiative decay</kwd><kwd>radiative recombination</kwd><kwd>nonequilibrium parameter</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Черевко А.
