53 maize standard samples diffuse reflectance spectra were collected from 4000cm - 1 ~ 10000cm - 1 at 8 cm - 1 resolution on perkin - elmer spectrum one nts near - infrared instrument at different energy level . 3 samples were scanned 10 times repeatedly at 100 % , 76 % and 34 % energy level for energy variance analysis 结果表明，随着仪器能量降低，模型相对标准偏差( rsd )有增大趋势，仪器相对能量从100衰减到18后，模型预测值rsd从2 . 5增至4 . 72 。
