| 摘 要： | 处于静电场中的介质要被极化,极化产生的束缚电荷要产生束缚电场,该电场叠加到原来的电场中,构成静电平衡时的总电场.本文讨论了电场场量在真空中和在介质中表述的转化,说明当把场量中的介电常数0ε从换为ε时,其中已考虑了束缚电荷对场量的贡献,对场量无需作进一步处理即得到介质中场量的表述.

| Abstract: | Electric medium in electrostatitc field will be polarized,and polarization produces polarization charge and polarization field.Original field and polarization field make up of total electrostatitc field.In this short paper,we discuss the transformation of electric field from vacuum to medium through replacing permittivity from vacuum to medium in the expression,and do not need to consider effect of polarization charge. |
