摘要：

A quantitative near-infrared spectroscopy (NIRS) method was developed for the determination of the kinematical viscosity of aviation kerosene in terms of chemometrics. Reference measurement was performed by ASTM445. The calibration model of aviation kerosene was established by partial least-squares (PLS) regression. Satisfactory calibration statistics were obtained with a standard error of calibration (SEC) of 0.012 mm(2)/s and a standard error of prediction (SEP) of 0.027 mm(2)/s. A t-test showed that the NIRS model had an accuracy equivalent to that of ASTM445 in the analysis of the kinematical viscosity of aviation kerosene. The study emphasized the potential of NIRS as a rapid and highly effective alternative analysis method to the conventional quantitative analysis of kinematical viscosity of aviation kerosene.
