And the energy of the photon is also equal to Planck’s constant times the frequency.

光子的能量也等于普朗克常数乘以频率。

So every single synapse is going to have some given time constant.

所以每个突触都将具有某个给定的时常数。

In my industry though, I meet so many different people all the time, constant, constant, constant.

我的行业里，我总是不断地、持续地遇到形形色色的人。

So you have a constant time under tension because there's no rest points either.

所以你有持续的张力时，因为没有休息。

This time constant has all kinds of mathematical meaning that we can't get into right now.

这个时常数 具有我们法理解的各种数学含义。

Energy of a photon is Planck's constant times the frequency.

光子的能量是普朗克常数乘以频率。

And the energy of the photon is also equal to Planck's constant times the frequency.

光子的能量也等于普朗克常数乘以频率。

And the time constant lets you know how long you need to press down on the accelerator to get there.

时常数让您知道您需要多长时按下加器才能到达那里。

Over time, constant acid leakage from heartburn may form scar tissue, which narrows the esophageal tube, making it harder to swallow food.

随着时的推移， 胃灼热导致的持续酸液泄漏可能形瘢痕组织，这些瘢痕组织会使得食管管腔变窄， 从而使吞咽食物变得困难。

A large time constant means the opposite: that a lot of time is necessary to speed up and slow down.

加和减需要大量时。

A small time constant means less time is needed to reach maximum speed, and also less time to slow down to a stop.

较小的时常数意味着达到最大度所需的时更短，减停止所需的时也更少。

And so we can measure that energy using Planck's equation where h times nu is going to be Planck's constant times the frequency of the light.

因此, 我们可以使用普朗克方程来测量能量, 其中h乘以nu将是普朗克常数乘以光的频率。

And Einstein showed that the amount of energy in a photon is equal to H. And H is equal to Plank's constant times the frequency of the light.

爱因斯坦证明，光子的能量等于 H，而 H 等于普朗克常数乘以光的频率。

And we would use the particle model if the energy that we are studying is comparable to the energy of a photon, remember which is described as Plank's constant times the frequency of the photon itself.

如果我们研究的能量与光子的能量相当， 我们就会采用粒子模型。记住， 光子的能量被描述为普朗克常数乘以其自身的频率。
