帮我润色这一段话：近红外光谱原始光谱曲线以及平均光谱曲线如图 4 4、图 4 5所示。其中近红外漫反射光谱的波谷和波峰主要在1400nm-1600nm之间近红外破壳漫反射光谱的波谷和波峰主要在1000nm-1200nm之间。从原始光谱曲线中可以看出不同性别的曲线很难单纯从反射率的数值大小上区分开从平均光谱曲线可以看出在漫反射光谱曲线中不同性别在900nm-1350nm与1420nm-1600nm两

The original and average spectra of near-infrared (NIR) reflectance and transmittance are shown in Figures 4 4 and 4 5, respectively. The valleys and peaks of the NIR diffuse reflectance spectra are mainly between 1400nm-1600nm, while those of the NIR transmittance spectra are mainly between 1000nm-1200nm. From the original spectra, it is difficult to distinguish between different genders based solely on the reflectance values. However, the average spectra reveal significant differences between genders in the 900nm-1350nm and 1420nm-1600nm bands for diffuse reflectance spectra, and 950nm-1050nm and 1200nm-1600nm bands for transmittance spectra. These differences are due to the influence of the eggshell, which results in variations in different bands.
