摘要
Abstract
The application of SVD denoising was studied in the preprocessing of infrared spectrum. The principle of largest spacing and maximum peak was adopted to choose effective rank order. The original spectrum was preprocessed by SVD denoising and the first derivative, the wave wand were selected with the method of correlation coefficient. Calibration mod-el for kinematic viscosity was established using the PLS method, and was compared with convolution smoothing. Its R c was 0.9779, its SEC was 0.1005, its Rp was 0.9412, its SEP was 0.1547. The results showed that SVD and the first derivative could effectively conduct denoising, correct baseline drift and improve the accuracy of PLS model.关键词
