Normally, these dipoles cancel each other out, so there's no net separation of charge in the unit cell.
通常情况下, 这些偶极子会相互抵消,因此晶胞中不会出现净电荷分离。

Through a process that's still not entirely understood, the collisions cause a separation of charges within the cloud.
通过一个尚未完全了解的过程,碰撞导致云内电荷分离。

And so for this molecule, we're going to get a separation of charge, a positive and a negative charge.
所以对于这个分子,我们将分离电荷,一个正电荷和一个负电荷。

The oxygens have a slight negative charge and silicons have a slight positive, creating a separation of charge, or a dipole along each bond.
氧带有轻微的负电荷, 硅带有轻微的正电荷,形成电荷分离,或沿每个键形成偶极子。
化学 Crash Course
As you should recall from our lesson on polar and non-polar molecules, a dipole is a separation of charges, like areas of partial positive and partial negative in a polar molecule such as water.
In physics, the electric dipole moment is a measure of the separation of positive and negative electrical charges in a system of electric charges, that is, a measure of the charge system's overall polarity. The SI units are Coulomb-meter (C m), however the most commonly used unit is the Debye (D). The electric field strength of the dipole is proportional to the magnitude of dipole moment.
