main shock 基本例句 主震,本震 Aftershocks are generally weaker than the main quake, but buildings that have already been damaged are prone to collapse in an aftershock.通常余震比主震弱,但是,在主震中受损的建筑往往因余震倒塌。 However, the earliest long-period seismographs recorded dispersive waves with large transverse displacement components in the main tremor.但是,最早期的地震记录,就记录下了主震中具有很大横向位移分量的频散波。 |
