| 摘 要： | 采用互相关分析，研究近红外光谱的模型传递问题。提出了对2台近红外光谱仪所采集的光谱数据分别进行互相关运算以后，所得到的2台光谱仪的互相关函数之间存在1个固有倍率常数的假设，并且通过实验证实了这个假设。通过补偿这个倍率常数，从而增强了模型之间的兼容性，得到了很好的预测结果。

| Abstract: | Model transfer was studied by cross-correlation in near infrared spectrum. The hypothesis is that there exists an inherent proportional constant between the two spectra for model building measured by two different spectrometers after cross-correlation analysis is put forward and approved. The compatibility of the two models is enhanced after using the proportional constant. So the good resuits were obtained. |
