Спектры образцов, полученные с разрешением во времени, преобразуются в частотные спектры с помощью быстрого преобразования Фурье и затем строятся спектральные кривые коэффициентов поглощения образцов. Данные по коэффициентам поглощения, обработанные с помощью модели ВДА, позволяют найти степень идентификации выбранных образцов: 89.4, 89.7 и 92.5%. Экспериментальные данные показывают, что терагерцовая спектроскопия в сочетании с ВДА является новым эффективным способом обнаружения видов генетически модифицированного хлопка.</p></abstract><trans-abstract xml:lang="en"><p>Terahertz spectroscopy combined with weighted discriminate analysis (WDA) is performed with different transgenic cottons (HD-1, HD-73, and Coker 312). The time-domain spectra of the samples are transformed into frequency-domain spectra by using fast Fourier transform. Then the absorbance curve of the samples is obtained. By applying the absorbance data in conjunction with the WDA model, the identification rates of the different transgenic cottons are 89.4, 89.7, and 92.5%, respectively. The experimental results demonstrate that THz spectroscopy combined with WDA is a novel and feasible way to detect transgenic cottons.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>взвешенный дискриминантный анализ</kwd><kwd>терагерцовая спектроскопия</kwd><kwd>генетически модифицированный хлопок</kwd><kwd>WDA</kwd><kwd>terahertz spectroscopy</kwd><kwd>transgenic cotton</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">H.
