At the same time , it is suggested that how to load samples is still an important issue in nir diffuse reflectance analysis 由于装样误差在模型整体误差中所占比重较大,所以严格控制装样在漫反射近红外分析中仍是一个值得注意的问题。
Delay in three models a pattern of delay or closure of the extension opened pm , the choice ranging from 0 . 1s to 5s dc output transistor sensor has dual npn pnp light diffuse reflectance sensor to regulate and control functions 有三种延时模式一次使用模式,打开延时或关闭延时,选择范围从0 . 1s至5s dc传感器具有双重npn pnp晶体管输出
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 。
