The technology of spectral recognition is key to spectral quapitative analysis . for quickly recognising spectral signal , the method of spectral recognition based on based on multiple features and neural network is adopted . the model transfer is a basic method to solve universal and comparable performance of spectrometers . the method based on support vector machine and piecewise direct standardization is put forward for solve the question of nonlinearity 、 small - sample 深入探討了光譜信號的識別問題,對光譜識別的基本方法和光譜信號的特征提取方法進行了相應的分析研究,提出了采用多特征和神經網絡構建光譜識別框架的方法,以實現光譜信號的快速正確地識別。
