| 中文摘要: |
| 采用核磁共振法测定乙烯-乙酸乙烯酯（EVA）中的乙烯和乙酸乙烯酯的相对含量。通过1H-NMR谱、13C-NMR谱和二维核磁共振谱对EVA的谱峰进行归属，选取特征峰的峰面积进行计算，分别建立1H-NMR和13C-NMR的定量方法，该方法相对于传统方法更加快速、简单。 |
| 英文摘要: |
| The relative content of ethylene and vinyl acetate in ethylene-vinyl acetate（EVA） was determined using nuclear magnetic resonance（NMR） spectroscopy.The peaks in the EVA spectra were assigned using 1H-NMR，13C-NMR，and two-dimensional NMR spectra.Characteristic peak areas were selected for calculation and quantitative methods were established for both 1H-NMR and 13C-NMR spectra.This method was faster and simpler compared to traditional methods. |
