For it has an extremely high spectral resolution, such data has facilities to the physicochemical characteristics mining or subtle recognition of different ground objects.
Spectral pattern recognition techniques are employed to suppress the strong and highly varying background to extract the very weak emission features from the compound spectra.
谱的模式识别技术可用于强变化的背景压缩和提取化合物极为弱小的发射特征。
