摘　　要：为了分析乙丙共聚物的序列结构,采用分峰法和分区法分别对13C-NMR图谱进行定量计算.研究结果表明,分峰法计算过程中峰的积分较复杂,查找峰的归属较烦琐,有些峰难以查找对应的序列结构;而分区法无需查找峰的归属,直接根据选定区域强度按设定模式进行计算,准确快速地计算出乙丙共聚物的序列结构.分区法可通过在VC++6.0和MATLAB7.1环境中编译程序进行计算,结果与分峰法相同.所以计算程序化使以往烦琐的手工计算更加便捷快速.In order to analyze the sequence of ethylene-propylene copolymer structure, the peak separate calculation method and sub-area calculation method were used to calculate the ^13C-NMR spectrum quantitatively. The results showed that the peak separate calculation method had the more complex integration, search peaks are cumbersome and difficult to identify some peaks corresponding to the sequence structure, but in the other method, it was unnecessary to search each sequence attribution, under the direct intensity of selected regional fixed model calculation. With using of VC＋＋ 6.0, MATLAB 7.1 compiler, and the comparing of two test calculation, calculation procedures was rapid, imple and accurate. So the calculation procedures of the cumbersome manual calculation became more convenient.
