These jets are subdivided into several groups characterized by different formation mechanisms and substantial variation of their characteristics. In order to distinguish separate groups of jets and identify them with respective formation mechanisms, we performed a statistical study of the full ensemble of solar extreme ultraviolet (EUV) jets using observations from the Solar Dynamics Observatory (SDO) in the 171, 193, and 304 Å channels. We identified a total of 212 such events, of which 26 % were classified as linear jets, probably generated by magnetoacoustic shocks, and 30 % as helical jets, representing small-scale filament eruptions. We found that these two groups differ significantly in their major dynamic characteristics (maximum height, initial velocity, and lifetime), as well as in their widths that are closely related to the underlying magnetic field structure, while helical jets were also shown to be much more frequently associated with the presence of hot coronal component. At the same time, we found a third class of jets with intermediate characteristics and unknown formation mechanism, requiring further study.</p></abstract><trans-abstract xml:lang="ru"><p>Струеобразные выбросы вещества, иначе называемые джетами, в большом количестве наблюдаются в хромосфере и нижней короне, и представляют значительный интерес с точки зрения их возможной роли в переносе вещества и энергии в атмосфере Солнца. При этом наблюдается несколько групп солнечных джетов, вероятно, имеющих различный механизм формирования и существенно различающихся по своим характеристикам. С целью выделения отдельных групп джетов и отождествления их с различными физическими механизмами, в настоящей работе проводится статистическое исследование полного ансамбля джетов, наблюдаемых в диапазоне вакуумного ультрафиолета (ВУФ) при помощи <italic>Обсерватории Солнечной Динамки</italic> (<italic>SDO</italic>) в каналах 171, 193 и 304 Å. Всего было зарегистрировано 212 событий, из которых 26<sub> </sub>% отнесены к подмножеству линейных джетов, с вероятным механизмом ускорения магнитоакустическими ударными волнами, и 30<sub> </sub>% – к подмножеству спиральных, представляющих собой выбросы мелкомасштабных филаментов. Показано, что указанные группы джетов существенно различаются по своим основным динамическим характеристикам (высота подъёма, начальная скорость движения и время жизни), а также по ширине, связанной с исходной структурой магнитного поля; при этом спиральные джеты также значительно чаще ассоциированы с наличием горячей корональной компоненты. В то же время, обнаруживается третий класс джетов, имеющий промежуточные характеристики, механизм формирования которых остаётся неясным и требует дальнейшего изучения.</p></trans-abstract><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский Научный Фонд</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap></funding-source><award-id>21-72-10157</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Shen Y.
