Some of them were over 5 kilometers below the water surface.

其中一些地震仪被放在水面以下5里处。

Scientists record these waves on a device called a seismograph.

科学家用地震仪这装置来记录地震波。

The device InSight uses to measure ground movements is called a seismometer.

“洞察号”用来测量地面运动的设备被称为地震仪。

The crash sends energy through the ocean floor where it can be measured by seismographs.

撞击产生的能量穿底，在底可以用地震仪测量。

But Bromirski said large waves create enough energy to be measured by seismographs, also.

但布罗米尔斯基说，巨浪也能产生足够的能量供地震仪测量。

The snag lies with the seismometer, capable of measuring group movement as small as the diameter of an atom.

问题出现在地震仪，它可以检测小至原子级别的地面运动。

Those measurements permitted Bromirski to judge the strength and size of waves over a period of 90 years.

地震仪在底测量的数据使布罗米尔斯基能够判断90年来浪的强度和大小。

That is a part of Mars where some kinds of seismic waves cannot travel directly to InSight's seismometer.

这是火星的一部分，在那里，某些类型的地震波无法直接到达“洞察号”的地震仪。

Dark fiber covers much of the country, and stretches across the ocean basins-which are hard to study using traditional seismometers.

暗光纤覆盖全美大部分地区，并延伸至洋盆地地区，而洋盆地很难用传统的地震仪来研究。

A woman was introducing a self-adjusting seismograph to some people.

一位妇女正向人们介绍一种自动调节的地震仪。

It's got an arm… It can listen with its seismometer.

它有一只手臂… … 它可以用它的地震仪听。

He was like, he was like one of those machines that register earthquakes 10,000 miles away.

他就像一台地震仪，能探测到万里之外的地震。

Geologists have long used seismometers to track and map these tiny shifts in the earth's crust.

地质学家早已使用地震仪来追踪、绘制地壳中的这些微小变化。

They got into a debate with the Soviet delegation over which nation's seismometers were superior.

他们与苏联代表团就哪国家的地震仪更先进进行辩论。

Scientists have been trying to replicate this seismoscope for centuries, even as recently as 2005, all unsuccessfully.

几世纪以来， 科学家们一直在尝试复制这种地震仪，甚至最近在 2005 年， 都没有成功。

Here's an example seismometer signal and its Fourier transform.

这是一地震仪信号及其傅里叶变换的示例。

29 small, underwater observatories, equipped with pressure sensors, seismometers and accelerometers, are installed directly on the fault-line off the coast of Osaka.

29小型水下观测站，装备有压力传感器、地震仪和加速度计，直接安装在大阪岸的断层线上。

In an earthquake, some vibrations bounce off the seafloor and turn into sound waves that get picked up by seismometers and underwater microphones.

在地震中，一些振动从底反射回来，转化为声波，被地震仪和水下麦克风接收。

That sounds a silly suggestion, but that was precisely the idea adopted in some of the early instruments (seismometers) for recording earthquake waves.

这听起来似乎是一种愚蠢的想法，但是早期记录地震波的仪器（地震仪）正是采用这种思路。

But the seismometer signal depends not only on the yield of the device but also on how deep it was buried.

但地震仪信号不仅取决于设备的产量，还取决于它埋藏的深度。
