The experts say you will see that with much increased frequency over time."

VOA: standard.2009.12.12

It has to do with frequency ratios that we'll go in to a little bit next time.

它和频率比有关,下次我们再详细介绍

In the works that Milton is going to be publishing now with greater and greater frequency, it's this Spenserian ideal of marriage that will be the new and, believe me, the endlessly complex Miltonic subject.

在弥尔顿准备出版的作品中,越来越常出现的，是斯宾塞式的婚姻理想，那将是崭新的，相信我，也是无尽而复杂的弥尔顿风格的题材。

So, that was frequency with kinetic energy.

这是频率和动能。

So, if we start instead with talking about the energy levels, we can relate these to frequency, because we already said that frequency is related to, or it's equal to the initial energy level here minus the final energy level there over Planck's constant to get us to frequency.

如果我们从讨论能级开始，我们可以联系到频率上,因为我们说过频率和能量相关,或者说等于初始能量,减去末态能量除以普朗克常数。

So this is our final equation, and this is actually called the Balmer series, which was named after Balmer, and this tells us the frequency of any of the lights where we start with an electron in some higher energy level and we drop down to an n final that's equal to 2.

把2代入到这里，所以得到1除以,这就是我们最终的方程，这叫做Balmer系，以Balmer名字命名的,它告诉我们从高能级掉到n等于2的,最终能级所发出光的频率。
