Very few seismograms showing motion near to the source are available . 可以利用的记录震源附近运动的地震图很少。
It is quite rare that more than two reflections from the earth's surface are clearly readable in seismograms . 地面上两次以上的反射很少可从地震图中清楚地分辨出。
Development of the inquiring software for digital seismic database and its application in shandong network stations 数字地震图文库查询软件开发及其在山东台网的应用
The record of the wave called a seismogram imprinted on paper , film , or recording tape or is stored and displayed by computers 称作地震图的震动波的记录被刻录在记录纸、胶片或磁带上,或者由计算机来储存和显示。
In this study , a composite source model has been used to calculate the realistic strong ground motions in beijing area , caused by 1679 ms8 . 0 earthquake in sanhe - pinggu 摘要利用复合震源模型和人工合成地震图的算法,以1679年三河平谷m (下标s ) 8 . 0地震为例,计算了北京地区的宽频带强地面运动。
In order to calculate synthetic seismograms in a layered half - space with the sources and the receivers at close or same depths , an efficient numerical integration method - the peak - trough averaging method ( ptam ) is proposed , based on the repeated averaging method 摘要为了计算在震源和接收点深度相同或相近情况下分层半空间介质中的合成地震图,在重复平均法的基础上加以改进,提出一种有效的数值积分方法峰谷平均法。
