Those last three are called latent pacemakers, and they have slower depolarization rates - which is the rate at which they fire off electrical signals - and they get slower as you move further down.

后三者被称为潜在起搏点，他们去极化速率更慢（在这个速率下它们发射电信号）向下级更远传导时，它们会变得更慢。

Excitatory neurotransmitters depolarize the postsynaptic neuron by making the inside of it more positive and bringing it closer to its action potential threshold, making it more likely to fire that message on to the next neuron.

兴奋性神经递质过使突触后神经元内部更加积极并使其更接近其动作电位阈值来去极化突触后神经元，使其更有可能将该信息发送到下一个神经元。

Yeah. We're in a society right now where the immediate question… Moderation of certain things in your habits definitely is part of what depolarization is all about.

嗯。我们现在所社会中，直接问题… 在你习惯中适量某些东西肯定去极化一部分。

Normally, the resting state of sodium channels is stabilized by calcium ions, which prevents them from spontaneously opening and potentially causing depolarization.

正常情况下，钙离用来稳定钠离静息状态，这可以防止钠离自发打开，从而导致去极化。

And, to the degree that the heart's in-between, the heart will be depolarized and normal rhythm will, will be restored.

当心脏于这两者之间时，心脏会去极化，恢复正常心律。

Most cells in your body only depolarize after being triggered by an external stimulus, or by a neighboring cell, in a long chain reaction of action potentials that's set off by the nervous system.

你体内大多数细胞只有在被外部刺激或邻近细胞触发后才会去极化，这由神经系统引发动作电位长链反应。

Remember that at rest, cells are negatively charged relative to the slightly positive outside environment and when they depolarize, the cells become positively charged, leaving a slightly negative charge in the outside environment.

要记住在静息状态下，细胞带负电，其外部环境则相对稍带正电；当它们去极化时，细胞带有正电，它外部环境带有负电。

But eventually, the resting membrane potential gets so high that it's above the threshold potential, meaning that once the muscle depolarizes and contracts, it can't repolarize to allow another contraction.

但最终，静息电位变得太高，以至于超过阈值点位，这意味着一旦肌肉去极化收缩，就不能复极化以进行下一次收缩了。

Moderation in your opinions, moderation in your principles, moderation in your convictions is not what depolarization is about.

你观点要适度，你原则要适度，你信念要适度，这不去极化意义所在。

On an electrocardiogram or ECG which measures the electrical activity of the heart via electrodes that are placed on the skin, the atrial depolarization, and therefore its contraction, is seen as a p-wave.

在过置于皮肤电极测量心脏电活动心电图上，心房去极化，即心房收缩，显示为P波。

With low levels of extracellular calcium, voltage-gated sodium channels are less stable and more likely to open up, which allows the cell to depolarize more easily, and makes the neuron more excitable.

当细胞外钙水平较低时，电压门控钠离不稳定，更容易开放，这使细胞更容易去极化，并使神经元更易兴奋。

That process started by depolarizing the cell — that is, pushing the cell's membrane potential from negative toward positive, past a threshold that triggered voltage-gated ion channels to open.

这个过程从细胞去极化开始——也就说，将细胞膜电位从负极推高到正极，超过了触发电压门控离打开阈值。

Finally, the signal disperses out into Purkinje fibers, which trigger depolarization in all surrounding cells, causing the ventricles to contract from the bottom up like toothpaste tubes, at which point the whole cycle starts all over again.

最后，信号分散到浦肯野纤维中，触发周围所有细胞去极化，导致心室像牙膏管一样自下而上收缩，此时整个循环重新开始。

When a cell depolarization happens during ventricular repolarization, it's called an early-afterdepolarization, and if it happens after repolarization is finished, it's called a delayed-afterdepolarization.

当一个细胞去极化发生于心室复极化期间，它就叫做早后除极；如果它发生于复极化结束之后，它就叫做迟后除极。

Next, the ectopic beat could happen during the PR segment, and because the ectopic depolarization happens relatively slowly, oftentimes, it will combine with the normal depolarization wave coming down the ventricular conduction system, resulting in a ventricular fusion beat.

其次，异位心搏可能发生在PR间期，因为异位去极化相对缓慢，它常会和在心室传导系统中下行正常除极波融合，导致室性融合心搏。

But that is not the case for a special group of cells found only in your heart — ones that can trigger their own depolarization.

但这并不适用于仅在你心脏中发现一组特殊细胞——它们可以触发自己去极化。

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了，由于细胞外电荷没有变化，所以没有双极，（心电图）上也就不存在任何波形（呈一条直线）。

Now if we freeze this " wave of depolarization" as it's moving through the cells, half of the cells are positive or depolarized and half are negative or resting, and so there's a difference of charge across this set of cells.

当除极波正在流经这组细胞时，如果我们把它“冻结”起来，这时一半细胞带有正电（去极化）而另一半则带负电（于静息状态），因此在这组细胞里存在两种不同电荷。

For those whose compasses were not depolarized there seemed many odd things in these houses.

对于那些罗盘没有去极化人来说，这些房里似乎有很多奇怪东西。

But then the metabolism of that glucose that produces the ATP and further depolarizes the cell, we believe that it will cause the release of the hormone, of the neuropeptide.

然而， 葡萄糖代谢产生ATP并进一步使细胞去极化，我们认为这会导致激素，即神经肽释放。
