摘要
用冷冻介电谱方法将聚对苯二甲酸乙二醇酯在液氮温度下冷冻下来的驻极体效应的不同微观机构分开，得到１个快极化和３个偶极取向慢极化成份．
Frozen dielectric spectroscopy is applied to study electret effect for Polyethylene Terephthalste at liquid nitrogen temperature and four different microscopic responses are observed:one of them is fast and other three are slow. The slow respouses are interpreted as being related to orientational polarization of local dipoles.
