英文: Abstract: When a cluster of particles is immersed in a uniform electric field,the particles are coupled together due to the mutual interaction among them.This interaction causes the dipole moment of the cluster to be dependent upon the spatial arrangement
中文: 文摘:置于均匀电场中的一簇球形颗粒,由于其内部的相互作用而耦合在一起.这致使簇的感应偶极矩与簇的几何结构,大小以及颗粒的介电常数等参量有关.试图通过已知的链的偶极矩确定任意大小长方结构的簇的偶极矩.假定颗粒链可以被具有同样偶极矩的一个等效介质球代替,并将具有空间结构的颗粒簇处理成面结构簇,再将面结构简化成一个颗粒链,从而确定簇的偶极矩.在这一过程中,通过不断增加等效球的尺寸,将颗粒间的相互作用包含在簇的偶极矩中.数值分析了立方结构簇的偶极矩,结果是可接受的.
