This part of the project is searching the nearest 1000 likely stars with high sensitivity for signals in the frequency range 1000 to 3000 MHz.

这部分项目搜寻离地球最近的1000颗可能存在的恒星，这些恒星对频率范围在1000到3000兆赫内的信号有着较高的灵敏度。

If we have a high frequency, what about the wavelength, long or short? All right. Good. So we should always be able to keep these relationships in mind.

如果频率高，那波长是长还是短？,好，不错，我们要记住这些关系,类似的。

Maybe you can put the frequency of the higher pitches as high so you can detect the sound quicker and That's it exactly.

大概是把频率调到更高的音高后,就能更敏捷地感觉到声音的变化,而那就是原因了

So that should mean that the energy that's transferred to the electron should be greater, but that's not what you saw at all, and what you saw is that if you kept the frequency constant there was absolutely no change in the kinetic energy of the electrons, no matter how high up you had the intensity of the light go.

所以这意味着转移到电子,上的能量也越大，但这并不是，我们观测到的现象,我们所看到的是,如果固定光的频率不变,不管光强如何变化,电子的动能没有任何变化。

So for the world as a whole, if a financial transactions tax put a bit of a dampener on financial innovation and trading (whether low frequency or high frequency), that would probably be no reason to weep - unless (to state the obvious) investment banking is your life.

BBC: How scary is a financial transactions tax?

The Securities and Exchange Commission has been studying a number of proposals that would put an extra burden on firms engaged in high frequency trading strategies or on firms assisting other firms with high frequency trading.

FORBES: Regulator Takes Aim at High Frequency Traders

Quill said some firms are turning to cross-asset trading because the high frequency trading (HFT) business is now dominated by ultra high frequency trading firms whose massive investments in sophisticated hardware like FPGAs has made it difficult for smaller players to compete.
