| Abstract: | In order to improve the prediction and the robustness of the near infrared spectroscopy(NIR) calibration models of jet fuel,the orthogonal signal correction(OSC) was used to preprocess the near infrared spectroscopy(NIR) of jet fuel.In this study,the numbers of principal component of OSC was chose by K-Matrix.The preprocessed spectrum were subjected to the multivariate calibrations of K-Matrix,principle component regression(PCR) and partial least squares(PLS) to predict the density and the kinematic viscosi... |
