农作物秸秆燃料特性的在线检测是其有效利用的重要环节。利用近红外光谱技术实现在线检测具有很大的潜力和挑战性。采用两种不同的光谱仪，研究了焦距、带速、积分时间等近红外光谱在线采集参数对光谱重复性的影响。用均方根（RMS）值评价光谱重复性。结果表明，积分时间对两种光谱仪的光谱重复性有显著影响。光谱重复性随积分时间的增加而增加。然而，对于两种不同的光谱仪，焦距和带速度对光谱重复性的影响是不同的。只有光谱仪A的焦距和带速对光谱重复性有显著影响。光谱重复性随焦距或带速的增加而降低。
On-line measurement of crop straw fuel properties is important for its effective utilization. Realizing on-line measurement using near infrared spectroscopy (NIRS) is potential but challenging. The influence of NIRS on-line acquisition parameters such as focal distance, speed of the belt, integration time on the spectral repeatability was studied using two different spectrometers. The spectral repeatability was evaluated by root mean square (RMS) value. The results showed that integration time influenced spectral repeatability significantly for both of the spectrometers. The spectral repeatability increased following the increase of integration time. However, the influence on the spectral repeatability of focal distance and speed of the belt were different for the two different spectrometers. Focal distance and speed of the belt had a significant influence on the spectral repeatability only for spectrometer A. The spectral repeatability decreased following the increase of focal distance or speed of the belt.
