dipolar relaxation

Study of Structure and the Dipolar Thermal Relaxation on γ-Irradiated PET Films

γ辐照PET的结构变化与偶极热松弛运动的研究

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 mechanisms for non-radiative energy transfer and the dipolar relaxation will be further studied in detail.

有关体系的无辐射能量转移和偶极弛豫机制将进一步探讨。

大分子中磁偶极弛豫的分离

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。
