Использование золотых наночастиц для компонентов сплавов приводит к повышению соотношения сигнал/шум в 1.5-2 раза. Применение красителя приводит к ухудшению этого соотношения. Показано, что эффективность поглощения лазерного излучения на поверхности не оказывает существенного влияния на абляцию при воздействии наносекундных импульсов на металлы. При этом накопления сигнала от трех импульсов с очищением поверхности достаточно, чтобы превзойти эффект от использования наночастиц.</p></abstract><trans-abstract xml:lang="en"><p>Two variants of magnesium alloys surface modification have been considered to increase the intensity of spectral lines. The use of gold nanoparticles for the alloys’ components leads to 1.5—2-times increase of signal-to-noise ratio. The use of a dye leads to the decrease of this ratio. It has been shown that the efficiency of laser radiation absorption on the surface does not influence substantially the ablation when metals are affected with nanosecond pulses. Moreover, the accumulation of signal from three pulses with surface cleaning is enough to overcome the effect from the use of nanoparticles.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лазерно-искровая эмиссионная спектроскопия</kwd><kwd>наночастицы золота</kwd><kwd>родамин 6G</kwd></kwd-group><kwd-group xml:lang="en"><kwd>laser-induced breakdown spectroscopy</kwd><kwd>gold nanoparticles</kwd><kwd>rhodamine 6G</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">D.
