Again, the bigger the dipole, the bigger the negative deflection.

同样，双极子（压差值）越大，负向的波形也就越大。

And they're putting together these radio dipoles.

们正在组装这些无线偶极子。

So each molecule has a dipole moment.

所以每个分子都有一个偶极矩。

Water and its useful little dipole moment can dissolve more compounds than any other chemical on Earth.

水及其有用的小偶极矩可以溶解比地球上任何其化学物质更多的化物。

This pair of particle is known as an electric dipole.

这对粒子被称为偶极子 的”。

Because of the resulting asymmetry in charge distribution, the dipoles no longer cancel each other out.

此产生的荷分布不对称，偶极子不再相互抵消。

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荷分离。

If we unpause this, then everything becomes depolarized, and since there's no difference in charge, now, there's no dipole, and so no deflection.

如果我们这时将其“解冻”，那么所有细胞都被去极化，细胞外的荷没有变化，所以没有双极子，（心图）上也就不存在任何波形（呈一条直线）。

So in our electric dipole the lines start at the positively charged particle and move toward the negatively charged one.

在双极性中，线开始 粒子带正并趋向负粒子。

If the magnitude of the positive charge in our electric dipole is doubled, then twice as many lines leave the positive point charge.

如果偶极子的荷加倍，它离开 正点荷线数的两倍。

The oxygens have a slight negative charge and silicons have a slight positive, creating a separation of charge, or a dipole along each bond.

氧带有轻微的负荷， 硅带有轻微的正荷，形成荷分离，或沿每个键形成偶极子。

Now, if there's a dipole vector pointing toward the positive electrode, then the ECG tracing shows it as a positive deflection - the bigger the dipole, the bigger the deflection.

现在，如果有一个双极子的向量指向正极，那么心图上显示出来的就是一个正向的波形，双极子（正负荷差值）越大，波形也就越大。

Magnetic sources are always dipoles, with a north and south pole, and magnetic field lines that leave from the north pole and return back to the south.

磁源始终是偶极子，具有北极和南极，以及离开北极并返回南极的磁力线。

Pausing halfway through again, now the vector dipole goes in the opposite direction, and faces the negative electrode, which means there will be a negative deflection on the ECG tracing.

在流经一半时再次“冻结”定格，现在双极子的向量会指向相反的方向，对着负极，这意味着在心图上会显示出一个负向的波形。

And for an electric dipole – which is one positive point charge and one negative point charge – the electric potentials from individual charges can be added together.

对两个荷组成的偶极分子 正负分，每个荷的势可以相加。

The ECG tracing shows a depolarization wave moving towards an electrode as a positive deflection, and one moving away as a negative deflection, each of which is proportional to the size of the dipole.

在心图上，向正极移动的除极波显示为正向的波形（向上的偏转），远离正极的则显示为负向的波形（向下的偏转），波形的大小与双极子（压差值）的大小成正比。

Ionic solids are basically just polarity taken to the extreme, so far that instead of having a partial positive and partial negative dipole moment, the electrons have completely transferred, creating two charged ions.

离子固体基本上只是极端的极性，到目前为止， 子已经完全转移， 而不是具有部分正偶极矩和部分负偶极矩， 从而产生两个带离子。

In order for a molecule to be polar, there has to be a dipole moment, a separation of the charge around the molecule into a more positive area and a more negative area.

为使分子具有极性，必须存在偶极矩，将分子周围的荷分离为更正的区域和更负的区域。

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.

你应该记得我们关极性和非极性分子的课程， 偶极子是荷的分离，就像极性分子（如水）中的部分正和部分负区域一样。

You also learned how to notate a dipole moment or charge separation of a molecule, the actual physical mechanism behind " like dissolves like" , and why water is just so dang good at fostering life on this planet.

您还学习如何记下分子的偶极矩或荷分离、“同类相溶”背后的实际物理机制，以及为什么水在培育这个星球上的生命方面如此出色。
