Получена алгебраическая система модифицированных уравнений Блоха, описывающая эффект двойного резонанса в Н-мазере и учитывающая произвольную сортировку атомов по всем состояниям. Это является принципиально важным при анализе работы двойной сортирующей системы Н-мазера.</p></abstract><trans-abstract xml:lang="en"><p>The hydrogen maser double resonance effect of a two-photon process, where Zeeman sublevels of the hydrogen atom ground state hyperfine structure applying the transverse magnetic field near the Zeeman frequency are involved, is considered. The new modified Bloch equations describing the effect and intended for arbitrary state selection system have been obtained and calculated. They play an important role in examining the case of a single-state selection in H-maser.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Н-мазер</kwd><kwd>магнитная сортирующая система</kwd><kwd>эффект двойного резонанса</kwd><kwd>H-maser</kwd><kwd>magnetic state selection system</kwd><kwd>double resonance effect</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">Andresen H.
