摘要
在教学实践中,借助于小分子液体模型和液体粘度表达式,结合高聚物结构的特点,阐明了高聚物熔体粘度与分子量的关系。论述集中于物理概念,避免了烦琐的数学推导,有助于对高聚物熔体粘度与分子量的关系获得进一步的了解。
In this article,the lattice model of liquid and the expression of liquid viscosity have been extended to elucidate the relationship between viscosity of polymer melts and molecular weights.In doing this,we focused attention to the physical concept and avoided tedious mathematical derivation.Thus this elucidation is of pedagogical meaning.
