What does the nano hertz in NANOGrav refer to explicitly?

NANOGrav 中的“纳赫兹”具体指的是什么？

A biological neuron fires, maybe, at 200 hertz, 200 times a second.

一个生物神元所发出的脉冲频 大约位于 200 赫兹，每秒 200 次。

So nano hertz is the gravitational waves frequency that we're looking at.

“纳赫兹”就是我们正在寻找的引力波频。

Well, baleen whales emit sounds around 14 hertz, the deepest among mammals.

须鲸能发出 14 赫兹左右的声音，是哺乳动物中最低沉的。

副栉龙的共振频一般低达40赫兹，这种声音几乎和雾角一样低了。

The females are at a much lower pitch. They were around 400 hertz.

HS：女性的音高要低得多。 它们的频约为 400 赫兹。

[Melany] It's this frequency from about 75 hertz up to about 100 hertz.

- [Melany] 这是从大约 75 赫兹大约 100 赫兹的频。

So he's flying at around 600 hertz.

GG：所以他以大约 600 赫兹的速度飞行。
