位移电流密度的分解及应用

Dividing and Applying of Displacement Current Density

研究发现,在空间介质场域中时变电场位移电流密度与麦克斯韦定义的时变电场位移电流密度是不一致的。时变电场位移电流密度应分解为时变电场两极板之间电流的源点电流密度与时变电场极化束缚电荷位移电流密度之和,因此建立了空间介质场域麦克斯韦第一修正方程。修正方程表明,空间介质场域仅仅存在时变极化束缚电荷位移电流和漏电流在该场域产生的时变磁场。该修正方程将对基于麦克斯韦第一方程建立的电磁场、电磁波及相关学科的理论与工程应用方程产生重大影响。

The paper is to present the finding based on research that Maxwell＇s first equation and displacement current density is incorrectly in the generalized space dielectric.Timing-varying displacement current density should be divided into time-varying electric field polarization bound charge displacement current density and the current density of current source point on the two plates of time-varying electric field of generalized space dielectric.Based on the research,Maxwell＇s first correct equation have been presented in generalized space dielectric.Maxwell＇s first correct equation show, time-varying magnetic field is established by the bound charge displacement current density and the conduction current density of generalized space dielectric.Maxwell＇e first correct eqation has deep influence on the discilines of electromagnetic field,electromagnetic waves and circuit.
