Для выполнения калибровки в качестве аналитической выбрана линия Pb I 405.78 нм. Коэффициенты линейной корреляции (R2) концентраций, полученных с использованием указанных калибровок, и данных стандартных образцов составляют 0.97916, 0.98462 и 0.99647 соответственно. По данным определения Pb в восьми образцах метод множественной регрессии обладает наилучшими характеристиками в сравнении с остальными двумя методами по средней относительной погрешности (ARE = 2.69%), максимальной относительной погрешности (MRE = 4.94%), среднему относительному стандартному отклонению (ARSD = 9.69%) и максимальному относительному стандартному отклонению (MRSD = 24.44%). Показано, что при определении Pb в образцах чайного листа Pu’er метод множественной линейной регрессии имеет преимущество по точности и воспроизводимости. </p></abstract><trans-abstract xml:lang="en"><p>Laser-induced breakdown spectroscopy (LIBS) is applied at natural atmosphere to compare the quantitative analysis performances of the toxic heavy metal element lead (Pb) in Pu’er tea leaves, determined by three calibration methods: the external standard method, the internal standard method, and the multiple linear regression method. The Pb I line at 405.78 nm is chosen as the analytical spectral line to perform the calibration. The linear correlation coefficients (R2) of the predicted concentrations versus the standard reference concentrations determined by the three methods are 0.97916, 0.98462, and 0.99647, respectively. The multiple linear regression method gives the best performance with respect to average relative errors (ARE = 2.69%), maximum relative errors (MRE = 4.94%), average relative standard deviations (ARSD = 9.69%) and maximum relative standard deviations (MRSD = 24.44%) of the predicted concentrations of Pb in eight samples, compared to the other two methods. It is shown that the multiple linear regression method is more accurate and stable in predicting concentrations of Pb in Pu’er tea leaf samples. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>спектроскопия лазерно-индуцированной плазмы</kwd><kwd>чайный лист Pu’er</kwd><kwd>количественное измерение</kwd><kwd>метод внешнего стандарта</kwd><kwd>метод внутреннего стандарта</kwd><kwd>метод множественной линейной регрессии</kwd><kwd>laser-induced breakdown spectroscopy</kwd><kwd>Pu’er tea leaves</kwd><kwd>quantitative measurement</kwd><kwd>external standard method</kwd><kwd>internal standard method</kwd><kwd>multiple linear regression method</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">S.
