dipolar relaxation

The activation energy of thermal relaxation of dipoles for main-chain segmental motion in amorphous region was decreased linearly and the time constant of dipolar thermal relaxation was increased exponentially with increasing of crystallinity.

被冻结的分子主链段偶极热松弛活化能随结晶度增大线性减小，热松弛时间常数则随结晶度的提高而呈指数增大。

The observation of the cooperative relaxation in a quite wide temperature range indicates that the dipolar relaxation of the dye is principally controlled by the glass transition at temperature tens degrees below T g.

在较大的温度范围内存在协同松弛，说明在低于Tg数十度的温度时，染料发色体的极化松弛仍然主要受聚合物玻璃化转变的控制。
