近红外光谱标准正态变量变换处理方法，主要是消除固体颗粒大小，表面散射以及光程变化对漫反射光谱的影响。-Near infrared spectrum standard normal variable transform processing method, mainly eliminate the solid particle size, surface scattering and the change of optical path of diffuse reflection spectra.

近红外光谱小波变换预处理方法，能将信号分解成一系列小波函数的叠加，这些小波函数都是由一个亩小波函数平移和伸缩得到的。-Near infrared spectra pretreatment method, wavelet transform signal can be decomposed into a series of wavelet function, the wavelet function is a function by a mu wavelet translation and sca
