关于电介质内部的极化电荷

About Polarization Charge Inside Dielectric

本文从电磁场理论出发，导出各向同性线性电介质内、极化电荷与极化率、极化率梯度、自由电荷、以及电场强度之间的普遍关系式，进而总结出不出现极化电荷的三种情况和出现极化电荷的四种情况．这是文献〔１〕，〔２〕。

This article just to the needs of electromagnetic theorem, bring abont the universal relation formula among polarization charge and electrictsusceptibility polarizability, the grad of electric susceptibility polarizabiliy, free electric charge, and electric field intensity in the isotropy linear dielectric. And then proceed to summarize three conditions, under which polarization charge does not appear, and fonr conditions, under which polarization charge appear. This is the problem that have been touched upon in the documents 1 2 3 , but not yet solved as a whole.
