    • An unknown spectrum obtained from infrared or other spectroscopy can be compared to spectra in a reference library to find the best matches. The best match spectra can then each in turn be combined with the reference spectra, with the combinations also being screened for best matches versus the unknown spectrum. These resulting best matches can then also undergo the foregoing combination and comparison steps. The process can repeat in this manner until an appropriate stopping point is reached, for example, when a desired number of best matches are identified, when some predetermined number of iterations has been performed, etc. This methodology is able to return best-match spectra (and combinations of spectra) with far fewer computational steps and greater speed than if all possible combinations of reference spectra are considered.
    • 可以将从红外或其他光谱获得的未知光谱与参考文库中的光谱进行比较,以找到最佳匹配。 然后可以将最佳的匹配光谱与参考光谱进行组合,同时对组合进行筛选以获得与未知光谱的最佳匹配。 所得到的最佳匹配然后也可以经历上述组合和比较步骤。 该过程可以以这种方式重复,直到达到适当的停止点,例如,当已经执行了一些预定数量的迭代时,当识别出期望数量的最佳匹配时,等等。该方法能够返回最佳匹配光谱 (以及光谱的组合)与考虑参考光谱的所有可能组合相比,具有远少的计算步骤和更高的速度。
