电介质极化

In the space filled with dielectric, Coulomb's law should be: F = kQ1Q2r2.V in the electric field generated dielectric polarization bound charge and bound charge generated within the medium electric field, and external electric field in the opposite direction, so to diminish the external electric field.

在充满电介质的空间里，库仑定律应为：F＝kQ1Q2r2.V在电场作用下电介质极化产生束缚电荷，束缚电荷在介质内部产生电场，与外电场方向相反，所以使外电场减弱。

In general we have two kinds of dielectric constant: the absolute dielectric permittivity, V the relative dielectric permittivity r, Vr = 0 = 1 , 0 means the vacuum dielectric constant, dielectric electrode means of EV \\ V \\ rate.

Mathematics model of dielectric under uniform electric field is built up, and total current is separated into three parts such as conductive current, instantaneous current and relaxation polarization current, then polarization and depolarization of linear and non-linear dielectric are simulated under step excitation, the results show that nonlinearity of non-linear conductivity is reflected by measuring surface potential attenuation during the process of self-discharge of non-linear dielectric.

论文首先对处于均匀电场下的电介质进行电路建模，把电介质的总电流分为电导电流、位移极化电流和松弛极化电流三部分来分析，然后以此为基础利用Matlab软件中的Simulink平台对直流阶跃激励下线性和非线性绝缘介质的极化和退极化过程进行了仿真，结果表明可以通过测试非线性绝缘介质自放电过程的表面电位衰减来反映其非线性电导的非线性程度信息。

However,there are also slow polarization effects,which can not be described using Maxwell's theory.For the description of both fast and slow polarizations,a concept of boundary screen charges is introduced to avoid the complex electric displacement in dielectrics.Using quantum statistics,the excitation theory of screen charges can explain many properties of electrets and ferroelectrics.

慢极化效应使电介质的极化偏离了麦克斯韦方程组描述的规律，引入边界屏蔽电荷的概念来描述介质的极化过程，可以回避电介质内部复杂的电位移运动，从而能用屏蔽电荷激发的量子统计理论来说明驻极体和铁电体的许多性质。
