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克常数乘以频率。

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

所以你有持续的间，因为没有休息点。

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 等于普克常数乘以光的频率。

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

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

随着间的推移， 胃灼热导致的持续酸液泄漏可能形成瘢，这些瘢会使得食管管腔变窄， 从而使吞咽食物变得困难。

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

间常数让您知道您需要多长间按下加速器才能到达那里。

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

在我的行业里，我总是不断地、持续地遇到形形色色的人。

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间常数。

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克常数乘以其自身的频率。

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

较小的间常数意味着达到最大速度所需的间更短，减速停止所需的间也更少。

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

光子的能量是普克常数乘以频率。

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

这个间常数 具有我们现在无法理解的各种数学含义。

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克常数乘以频率。

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

加速和减速需要大量间。
