The connection of these concepts with similar concepts of enveloping W*- and C*-algebras is considered. The equivalence of the concepts of injectivity and nuclearity for real C*-algebras is shown. As a consequence, nuclear real factors of types II<sub>1</sub>, II<sub>∞</sub>, III<sub>1, </sub>III<sub>0</sub> and III<sub>λ</sub> (0&lt; λ&lt;1) are completely described.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">В работе изучаются инъективные и ядерные вещественные W*- и C*-алгебры. Рассмотрена связь этих понятий с аналогичными понятиями обертывающих W*- и C*-алгебр. Показана эквивалентность понятий инъективности и ядерности для вещественных C*-алгебр. Как следствие, полностью описаны ядерные вещественные факторы типов II<sub>1</sub>, II<sub>∞</sub>, III<sub>1, </sub>III<sub>0</sub> и III<sub>λ</sub> (0&lt; λ&lt;1).</p></trans-abstract><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Аюпов Ш.
