本文用较少的几个正态分布函数叠加拟合真实聚合物的GPC谱图获得了良好效果,拟合线与实测谱图吻合较好。两个实测聚合物试样的单峰谱图都只需运用两个子函数叠加即可。叠加谱图用来分析平均分子量计算亦很成功。 In this paper, good results have been obtained by superimposing a few normal distribution functions on the GPC chromatogram of a real polymer. The fitted curve is in good agreement with the measured spectrum. The unimodal spectra of the two measured polymer samples are simply superimposed using two subfunctions. Superimposed spectra were also very successful in analyzing average molecular weights.
