摘要
本文介绍了非仿射变形假定和滑动函数的基本概念,利用Cox-metz关系式为一类中等稀聚合物溶液确定滑动函数的形式,带滑动函数的Rouse-Zimm模型被用来定量说明此类材料的非线性流变性,一些公开发表的实验数据被引证。理论结果与实验数据吻合良好。
Non-affine deformation and the slippage function are discussed. The slippage function is determined for some polymer solutions with moderate concentration by means of the Cox-Merz rule. The non-linear viscoelasticity of these solutions is described with the aid of the Rouse-Zimm model with slippage function. The theoretical predictions show good agreement with published experimental data.
