提出了一个基于局部组成概念上的核磁共振模型.利用该模型和以前别人提出的局部组成型粘度方程,成功地同时关联属于传递性质的粘度数据和属于波谱性质的核磁共振化学位移数据,关联所得到化学位移的平均绝对偏差小于0.0072,粘度的平均绝对偏差小于0.0006mPa@s,结果表明提出的局部组成模型是合理的.
提齣瞭一箇基于跼部組成概唸上的覈磁共振模型.利用該模型和以前彆人提齣的跼部組成型粘度方程,成功地同時關聯屬于傳遞性質的粘度數據和屬于波譜性質的覈磁共振化學位移數據,關聯所得到化學位移的平均絕對偏差小于0.0072,粘度的平均絕對偏差小于0.0006mPa@s,結果錶明提齣的跼部組成模型是閤理的.

A new model based on the concept of local composition has been proposed for the correlation of the NMR chemical shift data. Consequently, the viscosity and NMR chemical shift data were well correlated simultaneously using this model and the early proposed local composition viscosity equation. The resulting average absolute deviations of viscosity and NMR chemical shift are respectively less than 0.0006 mPa@ s and 0.0072, which suggested the reasonability of the proposed model.
