Методика основана на расчете амплитуды и фазы вынужденных колебаний газа в сферической полости. Рассчитаны теоретические резонансные линии при разных давлениях и температурах газа и проанализировано влияние акустических преобразователей и отверстий в оболочке резонатора на резонансные линии. Проведено сравнение рассчитанных частотных зависимостей акустического сигнала с зависимостями, измеренными на экспериментальном образце сферического резонатора, заполненного газообразным гелием.</p></abstract><trans-abstract xml:lang="en"><p>A procedure of precise modeling of acoustic resonance in spherical resonators filled with inert gas based on calculation of amplitude and phase of forced gas oscillations in spherical cavity was developed. The theoretical calculation of resonance lines was carried out for different gas pressures and temperatures. The influence of acoustic transducers and holes in resonator walls was theoretically analyzed. The calculated frequency dependencies of acoustic signals were compared with the dependencies measured on experimental spherical resonator filled with gaseous helium.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эталоны температуры</kwd><kwd>акустический газовый термометр</kwd><kwd>акустический резонанс</kwd><kwd>temperature standards</kwd><kwd>acoustic gas thermometer</kwd><kwd>acoustic resonance</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">Moldover M.
