- In pure seismology, the ground motion is generally expressed by its amplitude. 在纯粹地震学中，地面运动一般以振幅表示。
- This scale,commonly known as the Richter scale measures the ground motion caused by an earthquake. 这个震级，一般称为里氏震级，可测量地震引起的地面运动。
- The proplem is to recalculate these amplitudes into the corresponding amplitude of the ground motion. 问题是要将记录图振幅换算为相应的地面运动振幅。

- This scale, commonly known as the Richter scale measures the ground motion caused by an earthquake. 这个震级，一般称为里氏震级，可测量地震引起的地面运动。
- The ground motion at each seismometer is amplified and recorded electronically at a central recording site. 通过比较这些到达时间的数据，我们就可以找出未知地震的来源。
- This error results in using the ground motion uncertainty (spatial characteristic) to extrapolate occurrence of ground motion (temporal characteristic) or the ergodic assumption. 然而它在计算中却存在着一个错误：把强地面运动衰减关系（一个函数）的条件超越概率等同于强地面运动误差（一个变量）的超越概率。
- This paper presents an experimental method in situ,in which the artificial ground motion is simul taneously excited by the vibrators located at three points on the ground. 本文介绍一种新的现场试验方式:三点激振,研究了在不同类型起振机、不同形状振动基础条件下的人工地震增油技术,观察了增油效果。
- The ground was covered with ferns. 地面上长满了羊齿植物。
- He is assigned a room on the grind floor. 他分配到底层一间房子。
- The Richter Scale is a measure of ground motion. 里氏震级是测量地动的单位。
- He lifted a pail of water from the ground. 他把一桶水从地上提了起来。
- They put some wreathes on the ground. 他们把一些花环放在地上。
- The ground was ploughed and planted with corn. 地翻耕后种上了玉米。
- We need a mechanical digger to level the ground. 我们需要一台挖掘机来平整土地。
- In this paper, the ground motion of an isosceles triangular dike impacted by SH waves is discussed.The methods of complex function and moving coordinate system as well as a simple model are used here. 本文利用复变函数和坐标移动方法研究了SH波入射对柔性基础上等腰三角形坝体结构的影响。
- A good hot summer could dry the ground out. 一个炎热的夏天可以将大地干透。
- The fence posts were fixed firmly in the ground. 栅栏的立柱牢牢地固定在地上。
- On the basis of analysis on seismicity and seismotectonic background of the oilfield, the potential source zones are delineated, and the ground motion attenuation relation is determined. 本文分析了油田所在地区的地震活动和地震构造环境,并在此基础上划分出了潜在震源区,确定了地震动衰减关系,进行了地震危险性分析。
- The ground is shut in by a wire fence. 那块地被铁丝篱笆围住。
