| 摘 要： | 本文在不同时间安装的多台同型号近红外光谱仪上建立推进剂校正模型时,由于推进剂样品数量少且难于保存,新到仪器在建模时常遇到代表性样品数量严重不足.为此,提出将2台波长一致性好的近红外光谱仪器上采集的光谱组成一个混合校正样品光谱集,使用偏最小二乘法(PLS)建立模型的方法.结果表明,在用户缺少专业模型传递软件情况下,该方法...

| Abstract: | Model transfer is important to the application of near infrared(NIR) technology.In order to solve the problem of insufficient samples and difficulty in sample storing,a hybrid calibration model method was used to establish the calibration model of propellant.When the wavelength number obtained by two homotype NIR spectrometers was consistent,the spectra collected on both spectrometers could be mixed for the calibration set.The results obtained by PLS method showed that the hybrid calibration model method wa... |
