摘要：

Near-infrared reflectance spectrometry (NIRA) has been shown to be an accurate and rapid method of qualitative analysis when Mahalanobis distances are used to determine the classification of unknown samples. The use of this concept depends upon the data derived from the calibration samples having certain mathematical properties; in particular, each material in the calibration must occupy a region of multidimensional space that has the same size, shape, and orientation. In NIRA, the shape and orientation of these regions are the same, but the sizes can differ.
