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

子能量也等于普朗常数乘以频率。

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

这个时常数 具有我们现在无法理解各种数学含义。

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

子能量也等于普朗常数乘以频率。

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速器才能到达那里。

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时。

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

随着时移，胃灼热引起持续酸渗漏可能会形成疤痕组织，从而使食道管变窄，使吞咽食物变得更加困难。

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

较小时常数意味着达到最大速度所需时更短，减速停止所需时也更少。

If you just jug along with those computations, ignoring the weirdness, you get some constant times I had, plus some constant times Jay Hat, plus some constant times k Hat.

如果你继续计算 忽略这些奇怪地方 你会得到一个常数乘以我 加上一个常数乘以杰伊帽 加上一个常数乘以k帽。
