不同贮存温度蜂花粉的可见-近红外光谱鉴别(Application of Visible/Near Infrared Spectroscopy for Discrimination of Bee Pollen under Different Storage Temperature)
可见-近红外光谱技术 蜂花粉 贮存温度
2009/11/3
利用可见-近红外光谱技术结合最小二乘支持向量机(LS-SVM)对不同贮存温度下的蜂花粉进行鉴别。选择-20、4、15、25和40℃ 5个温度下分别贮存60d后的蜂花粉为研究对象。对原始光谱数据进行平滑和附加散射校正(MSC)的预处理后进行主成分分析,选择4~20个主成分作为输入变量进行LS-SVM建模。模型预测参数比较结果显示,当主成分数取20时模型的预测效果最好,预测相关系数r2p≥0.9919...

Cu-MCM-41介孔分子筛中不同价态铜上的吸附性能研究(Adsorption Behavior of Copper with Different Valences States in Cu-MCM-41)
Cu-MCM-41 介孔材料 CO吸附 C2H4吸附 吸附量热 红外光谱
2010/8/25
合成了不同铜含量的Cu-MCM-41,高温还原后仍具有良好的介孔结构。孔壁中的铜容易被H2还原为Cu(0)。通过在氦气流中加热,可以导致孔壁中的Cu(II)还原为Cu(I)。MCM-41中不同价态的铜具有不同的吸附性能:Cu(0)强烈吸附O2,吸附热高达427 kJ·mol-1;Cu(I)在室温下几乎不吸附O2,表明Cu(I)在室温下较稳定;而Cu(I)在对CO与C2H4的吸附中,除了CO的吸附热...
