1·An electronic receiver designed to pick up seismic vibrations.
因地震的震动力而摇动。
2·They are designed to pick up the echo of the seismic vibrations created by contraptions called "thumper trucks" pounding the ground.
一个名叫“桑普卡车”的小装置会敲击地面，引起的细微地面震动又再传输到无线传感器上。
3·When this stress is released quickly, it sends massive vibrations, called seismic waves, often hundreds of miles through the rock and up to the surface.
当地震发生的时候，地震波会通过岩石从数百里外传达到地表引起振动。
4·But on soft soils, vibrations from long-period seismic waves are amplified, possibly exacerbating the swaying of skyscrapers.
但是，在松软的土层上，长周期地震波的震动会被放大，可能使摩天大楼的摇摆更加剧烈。
5·The vibrograph can be used for observing seismic effects of explosions and measuring vibrations in engineering and construction work.
该仪器可用于爆炸地震效应观测和工程结构振动测量。
6·Harmonic distortion arises from the nonlinear vibrations of mechanical device of seismic source and the coupling between the vibrator and the ground.
由于震源的机械装置和振动装置的非线性振动以及振板与大地的耦合等问题，在震源向地下输入能量的同时，也产生了谐波畸变。
7·During a 18-storeyed building was demolished by blasting method, the vibrations from blasting and building collapse were measured by use of a GDQJ-1A scale of seismic intensity.
在十八层楼房爆破拆除中，利用GDQJ - 1a地震强度计测定了爆破震动和塌落震动。
8·Previous studies show that both dynamite borehole shots and vertical vibrations from controllable seismic sources at the surface will produce relatively strong pure P-waves and weaker pure S-waves.
已有的研究表明，炸药震源在井下激发、可控震源在地面垂向振动，均会产生较强的纯纵波和一定强度的纯横波；泊松比差别较大的分界面有利于形成较强的透射转换横波。
9·It USES the vibrations produced by a drill bit while drilling as a downhole seismic energy source.
随钻地震技术是利用钻井期间旋转钻头的振动作为井下震源。
