中文摘要：本文用太赫兹光谱结合加权判别分析方法对不同的转基因棉花（HD-1、HD-73和 Coker 312）进行了检测。作者用快速傅里叶变换方法将样本的时域光谱转换为频域光谱，并获得样本的吸光度曲线。通过将吸光度数据与WDA模型相结合，不同转基因棉花的识别率分别为89.4%、89.7%和92.5%。研究结果表明，太赫兹光谱技术结合加权判别分析方法是检测转基因棉花的一种可行方法。
外文摘要：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.
