摘要

　分析了高分子物理中WLF方程的适用温度范围.从微观的链段运动对方程进行了详细的剖析.高分子链非常大

链段运动比较复杂

使其具有了特有的温度依赖关系WLF方程

所以WLF方程在使用的时候有一定的条件限制

说明了由于参考温度的不同

C2取值不同的原因.

Abstract

Based on microcosmic segmental motion

WLF equation suit for the appropriate temperature in polymer physics was analyzed. Being the bigness macromolecule chain and complicated segmental motion

macromolecule has particular relations with temperature WLF equation

and WLF equation must be used in its limits. The reason for different C-1 and C-2 depending on reference temperature was also given.
