An axisymmetric high-frequency (5 MHz) electric discharge in a pin-to-pin configuration is considered. Numerical models are used that take into account the chemical kinetics of high-temperature air and plasma chemistry, in which the reaction rates are determined by the magnitude of the reduced electric field. Preliminary results of plasma activation of atmospheric pressure air by a pulse-periodic nanosecond discharge are presented in order to intensify the production of chemically active particles (by the example of atomic oxygen).</p></abstract><trans-abstract xml:lang="ru"><p>Представлены результаты численного моделирования импульсно-периодического наносекундного разряда. Рассматривается осесимметричный высокочастотный (5 МГц) электрический разряд в конфигурации иглаигла. Используются численные модели, учитывающие как химическую кинетику высокотемпературного воздуха, так и плазмохимию, в которой скорости реакций определяются величиной приведенного электрического поля. Представлены предварительные результаты плазменной активации воздуха атмосферного давления импульсно-периодическим наносекундным разрядом с целью интенсификации наработки химически активных частиц (на примере атомарного кислорода).</p></trans-abstract><kwd-group xml:lang="en"><kwd>nanosecond electric discharge in air</kwd><kwd>nonequilibrium plasma</kwd><kwd>arc discha</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>наносекундный электрический разряд в воздухе</kwd><kwd>неравновесная плазма</kwd><kwd>дуговой разряд</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке гранта Министерства науки и высшего образования РФ № 075-00270-24-00 и Программы №10 НЦФМ</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Starikovskiy A., Aleksandrov N. // Prog.
