然而，这里所说的仪器记录下来的只是地震波运动中的水平部份，地震波的运动实际比这要复杂得多。
The apparatus thus described, however, records only the horizontal component of the wave movement, which is, in fact, much more complicated.
本文根据变分原理，利用有限单元法分析在水平地震运动作用下圆柱形弹性储液罐的动力反应。
Based on the variational principle, the dynamic responses of flexible cylindrical liquid storage tanks, excited seismically have been analyzed by the finite element method.
然而，仪器的如此描画只能记录地震波运动中的水平方面的运动部分，而地震波运动实际情况复杂得多。
The apparatus thus described, however, records only the horizontal component of the wave movement, which is, in fact, much more complicated.
文中还从现今地壳运动角度，讨论了活动地块运动速率与强地震活动水平之间的可能联系。
Based on present crustal movement, the potential correlation between active crustal-block movement velocity and strong earthquake activity has been discussed.
地壳由半无限大的基岩上一层厚度为H的表土层组成，入射地震波为垂直的SH波，产生水平地面运动。
The crust is constituted by the rock and a surface layer of soil with depth H over it. The incident seismic wave is a vertical SH shear wave to cause horizontal ground motion.
