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

同样，双极子（压差值）越大，负向波形也就越大。

And they're putting together these radio dipoles.

他们正在组装些无线偶极子。

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.

水及其有用小偶极矩可以溶解比地球上任何其他化学物质更多化合物。

This pair of particle is known as an electric dipole.

粒子被称为偶极子 ”。

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

由于由此荷分布不称，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， 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.

如果我们时将其“解冻”，那么所有细胞都被去极化了，由于细胞外荷没有变化，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，线开始于 粒子带正并趋向于负粒子。

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

如果偶极子荷加倍，它离开 正点荷线数两倍。

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

氧带有轻微负荷， 硅带有轻微正荷，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，如果有一个双极子向量指向正极，那么心图上显示出来就是一个正向波形，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，现在双极子向量会指向相反方向，着负极，意味着在心图上会显示出一个负向波形。

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.

于由两个荷组成偶极分子 正负分，每个荷势可以相加。

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，向正极移动除极波显示为正向波形（向上偏转），远离正极则显示为负向波形（向下偏转），波形大小与双极子（压差值）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.

为了使分子具有极性，必须存在偶极矩，将分子周围荷分离为更正区域和更负区域。

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.

你应该记得我们关于极性和非极性分子课程， 偶极子是荷分离，就像极性分子（如水）中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.

您还学习了如何记下分子偶极矩或荷分离、“同类相溶”背后实际物机制，以及为什么水在培育个星球上命方面如此出色。
