| 摘 要： | 近年来将因子分析这一多变量统计分析技术成功地用于具有加和性的谱分析中。因子分析法可正确定出混合物中含有的物种(因子)数和各物种的含量(浓度),同时可将各组分的纯光谱由混合物的光谱中分离开。聚乙烯(PE)和乙丙橡胶(EPR)的二、三元嵌段共聚物(PE-EPR、PE-EPR-PE)构成的共混物结构、形态与结晶过程研究已有

| Abstract: | The feasibility of applying the method of factor analysis to X-ray diffraction spectra of PE/(PE-EPR) and PE/(PE-EPR-PE) blends was examined. The result of mathematical treatment is satisfactory. The number of species and compositions for eight kinds of both PE/(PE-EPR) and PE/(PE-EPR-PE) were determined. The separation of spectra peaks of each species in two kinds of blends contributing spectra intensities was carried out. |
