  • So, if instead you put your particle somewhere down here on the electric field, or on the wave, the electric field will now be in the other direction so your particle will be pushed the other way.

    还有方向,所以如果,你把粒子放在这下面,电场的方向相反,粒子会朝另一个方向运动。

  • So, instead of having the periodic variation of water, or the periodic variation of air density here we're talking about an electric field.

    不像水或者空气密度的,周期变化,我们这里,讨论的是电场。

  • Again, in an electric field line splitting observed, the intensity of the line splitting varying with the intensity of the applied electric field.

    结果也证明谱线在电场中也会分裂,而且其分裂程度,随电场强度变化而变化。

  • You've got a magnetic field, maybe even magnetic susceptibility, the electric field. We're not going to worry about these magnetic fields or electric fields in this class So, pretty much we're going to focus on this set of variables here.

    你也会引入磁场,或许甚至磁化率,以及电场,我们这堂课不需要关心,这些磁场或,电场之类的东西,基本上我们只关注,这里的一组变量。

  • We know what an electric field is, it's just a space through which a Coulomb force operates.

    我们知道,电场不过,是库仑力的作用空间。

  • If we put a dipole that has the freedom to move, we put that dipole in an electric field, it will align itself with the field lines.

    若我们将偶极释放到自由空间中,比如说放到电场里,他们会自动排序按同一方向。

  • And subsequently Starck did the analogous experiment but with an electric field.

    之后,斯塔克做了一个相似的实验,不过他在实验中用的是电场。

  • We can also do a similar thing, and I'll keep my distance from the board, but we can instead be holding x constant, for example, putting x to be equal to zero, and then all we're doing is considering the electric field as a function of t.

    我们也可以做类似的事情,把x固定为一个常数,例如令x等于零,然后,考虑电场作为时间的函数,这种情况下,我们划掉。
