摘要
将拉普拉斯变换应用于聚合物粘弹性理论,使粘弹性材料的特性函数如松弛模量、蠕变柔量以及表示动态力学性能的函数之间的关系简单明了,并用拉氏变换定义松弛谱和推迟谱,将各粘弹函数相互联系起来.
In this paper Laplace transforms is utilized in viscoelastic theory of polymers making the relations between various viscoelastic functions like relaxation modulus, creep compliance and functiqns representing dynamic behavior simple and clear, relaxation spectrum and retardation spectrum are defined in terms of Laplace transform to correlate all viscoelastic functions.
