结果表明：碱金属离子耗尽层厚度以连接时间的双曲正切函数形式增长；界面电场强度随连接时间单调上升，而耗尽层外的玻璃内电场强度单调下降；电场辅助阳极连接是否完成决定于待连接表面间是否形成紧密接触，而非电荷迁移量是否达到某一恒定值。

From the formula for the field strength of a point charge,by means of the transformation of the field strength tensor in the special theory of relativity,the laws of electrostatic field and magnetic field of steady current s are derived in this paper to give the students a better understanding of the consistency of electric field and magnetic field.

从点电荷的场强公式出发，根据狭义相对论中场强张量的变换，推导出了静电场和稳恒电流磁场的诸定律，使学生对电场和磁场的统一性有了更为深刻的认识。

Motor speed is controlled by varying the current in the field windings.for example,when the amount of current flowing through the field windings is increased, the field strength increases, causing the armature wingdings to produce a larger counter EMF which slows the motor.conversely,when the field current is decreased, the field strength decreases, and the motor speeds up because the conter EMF is reduced.

调速控制的不同目前在外地windings.for例如，当电流流动量的通过外地绕组是增加，电场强度的增加，导致电枢wingdings产生较大的反电势而减慢motor.conversely当外地电流降低，电场强度降低，电机的速度，因为conter电磁场降低。
