Метод основан на деформации поверхности контролируемой жидкости газовой струёй. Сформулированы критерии выбора параметров аэродинамического воздействия и заданного значения высоты углубления на поверхности жидкости. В связи со значительным влиянием плотности жидкости на результат измерения метод рекомендован для определения поверхностного давления поверхностно-активных веществ.</p></abstract><trans-abstract xml:lang="en"><p>The results of the theoretical and experimental investigations of the surface tension measurement method based on deformation of a tested liquid by a gas jet are presented. The choice of the parameters of the aerodynamic impingement and the predetermined value of the height of cavity on the liquid surface was made on the base of formulated criteria. Due to significant influence of liquid density on the results of measurement the method is recommended for the determination of the suface pressure of surface active agents.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поверхностное натяжение</kwd><kwd>измерение</kwd><kwd>струя</kwd><kwd>газ</kwd><kwd>углубление</kwd><kwd>жидкость</kwd><kwd>плотность</kwd><kwd>surface tension</kwd><kwd>measurement</kwd><kwd>jet</kwd><kwd>gas</kwd><kwd>cavity</kwd><kwd>liquid</kwd><kwd>density</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">Pat. 2192987 GB.
