zero displacement

The average velocity, in the latter case, would be zero, since the total displacement is zero.

对于后一种情况，因为总位移为零，所以平均速度应为零。

The article points out that the "I" of the Biot-Savart law includes not only conduction current but also displacement current, and certifies that displacement current's contribution to magnetic field is zero.

指出毕奥&萨伐尔定律中的I不仅只包含传导电流，也应包含位移电流，证明在一定条件下位移电流对磁场的贡献为零。

The average velocity, in the latter case , would be zero, since the total displacement is zero.

对于后一种情况, 因为总位移为零,所以平均速度应为零.

We now determine x such that the displacement of B's relative to B is Zero.

我们现在确定x,以使得B'点相对于B点的位移等于零.

The fluctuations of its displacement and momentum at zero-point are also given.
