ground-motion是什么意思 ground-motion在线翻译 ground-motion什么意思 ground-motion的意思 ground-motion的翻译 ground-motion的解释 ground-motion的发音

1. We derive and analyze sensitivity densities for two quantities derived from rotational ground-motion measurements: the rms (root-mean-square) amplitude A of the rotation seismogram and the apparent shear-wave speed, where Av denotes the rms amplitude of the velocity seismogram.
    笔者分析了从旋转地震动测量中得到两个参数的灵敏度密度。这两个参数是：旋转地震记录的均方根振幅，视剪切速度，表示速度地震记录的均方根振幅。

2. Rapid (3~5 minutes) generation of maps of instrumental ground-motion and intensity is accomplished through advances in real-time seismographic data acquisition combined with newly developed relationships between ground-motion parameters and expected shaking intensity values.
    通过对实时地震仪的数据采集，和新开发的地面运动参数和期望的震动烈度值之间的关系，美国已经实现了仪器地面运动和震动烈度图的快速（3～5min）产出。
