非极性电介质
nonpolar dielectrics
非极.曲电介质nonpolar dieleetries由非极性分子组成的电介质。即无外电场时,分子的正、负电荷重心相重合,不具有永久或固有偶极矩。 非极性电介质一般都具有对称的分子结构,呈各向同性的球对称性,可由圆球非旋转对称群cocom或Tco、表示。一些单原子分子(如He、Ne、Ar、Kr和Xe等)、双原子分子(如HZ、NZ和C12等)以及结构对称的多原子分子(如COZ、C6H6和CCI‘等)都是典型的非极性分子。 常见的绝缘材料如聚乙烯、聚四氟乙烯、石蜡、聚异T烯、未硫化处理的橡胶和绝缘油(如变压器油等)均属于非极性电介质。未经极化处理的压电材料如压电陶瓷、压电聚合物等也属于广义非极性电介质的范畴。 (周志刚)
