摘要: 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0.0006 mPa•s,结果表明提出的局部组成模型是合理的.

Abstract: 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.
