1、近红外荧光光谱仪光谱区范围，是介于可见光和中红外光之间的电磁波，在检测样品前我们首先需要了解测试光谱范围

1, the spectral range of near infrared fluorescence spectrometer is the electromagnetic wave between visible and mid infrared. We need to know the spectral range before detecting samples.

2、在使用前还需要对仪器进行校正，近红外荧光光谱仪的校正相对比较麻烦，为了得出准确的数值，一般需要80个以上的代表性样品用来进行校正，这一步骤我们通常称为模型建立

2, before using, we need to calibrate the instrument. The correction of near-infrared fluorescence spectrometer is relatively troublesome. In order to get the exact value, more than 80 representative samples are usually used for correction. This step is usually called model establishment.

3、在检测过程中，首先用近红外荧光光谱仪测定样品的光谱区，通过软件自动对模型库进行检索，选择正确模型计算待测样品质量参数

3, in the process of detection, we first use near infrared fluorescence spectrometer to determine the spectral area of samples, and retrieve the model database automatically by software, and select the correct model to calculate the quality parameters of the samples to be tested.
