图9 米粉水平直链淀粉敏感小波特征分布图
A: 蜡熟期; B: 黄熟期; C: 完熟期; D: 相应波长的米粉反射光谱。蓝色方框代表不同时期存在的相同敏感小波特征。蓝色虚线代表对应波长。黑色箭头代表淀粉吸收波段。
Fig. 9 Correlations scalograms for the identification of significant wavelet features of dried grain powder related to GAC
A: dough ripening stage; B: yellow ripening stage; C: full ripening stage; D: reflectance spectra of dried grain powder. The blue box represents the same sensitive wavelet features at different growth stages, while the blue dashed lines represent the corresponding wavelengths. The black downward arrows on the top of the figure indicate the wavelength locations of absorption features for starch.
