地震仪

The hum can only be detected by seismometers, and exists even when no earthquakes are occurring. Scientists are not yet sure what causes this, but several theories have been offered.

这种哼声只能由地震仪监测到，且在甚至没有地震发生的时候也存在，科学家还不确定是什么导致了这种现象，但已提供了几种理论。

Instruments called seismometers relay these reflected vibrations to a recording instrument.

一种叫地震仪的仪器把这种反射来的振动波转送到记录器上。

A seismograph is equipped with sensors called seismometers that can detect ground motions caused by seismic waves from both near and distant earthquakes.

地震仪配备了能探测到来自近震和远震的地震波所引起的地面运动的传感器，这个传感器被称为地震检波器。

We also discuss observations of infragravity waves on broadband ocean bottom seismometers located off-shore California, and their relationship to wind waves and seismic noise, showing that the ocean/solid earth coupling occurs near the coast.

我们也讨论了在加州近海布设的宽频带海底地震仪观测到的重力波以及它们与风波和地震噪音的关系，发现海洋/陆地的耦合发生在近海。

The main factor that affects the resolution of seismic prospecting is Earth's absorption and attenuation effect on high frequency signals. Study and calculation of Earth's absorption and attenuation effect show that medium deep and deep reflectors over 135 Hz can not be recorded even by 24-bit seismometers.

地震勘探分辨率不高的主要原因是地层对地震波高频成分的吸收衰减，通过对地层吸收衰减深入的理论计算可知，既便使用 2 4位遥测地震仪，在中深层勘探中也无法记录主频超过 13 5Hz的地震波。

The methodology has the advantages of advancement, scientificalness, practicability, high effectiveness, flexibility, tailorable ability, maintainability, extensibility and scalability.

提出浅层地震仪基于平台设计方法，此方法具有先进性、科学性、实用性、高效性、灵活性、可裁剪性、可维护性、可扩展性和可升级性。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
