| 摘 要： | 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。

| Abstract: | In the paper, two or more normal distribution functions are superim -posied to regressing GpC chramotogram of polymers and the regressing model curve is ccnfcrm with the actual chramotogram.Two polymer sampres were tested and it is only two functions are needed for regres-singl the suitable superimposical model of each chramotogram.The calaul-ated average molecalar weight of the model is in good agreement with that calculated from the actual GpC chramotogram.The model can be used to character the actual GpC chramotogram of polymers. |
