To strip it from sea - bed rock and transport it to seabank , it is necessary for us to understend the friability of cobalt crust 欲将结壳从海底基岩上剥离并采出海面，必要弄清钴结壳的破碎特性。
But faults and joints are often found in bedrock , which are the major channels the nuclides moved to the outer environment 但是由于在基岩中往往存在断层、节理，它们是核素向环境迁移的主要通道。
The goal of this paper is to develop the long period attenuation relationships for horizontal acceleration response spectrum of rock site in china 本文建立了我国水平向基岩长周期加速度反应谱衰减关系。
South slope is with rocks and very few of snow deposit . the north ridge is long and gentle covered with snow and oce . all these three peaks are 先热日峰山提破碎，基岩裸露，北面坡度较大，山脊线长，冰雪覆盖。
Rock slope ; modes of rock mass structure ; mechanism of deformation and failure ; destabilization of slope ; the reservoir area of the three gorges project 基岩斜坡岩体结构模式变形破坏机制斜坡失稳三峡库区
The ground seismic acceleration is conversed as the input seismic acceleration from bedrocks , which is useful in the next step 利用反演分析所得的地震加速度曲线作为基岩的地震输入曲线代入下一步动力分析步骤之中。
Stability against sliding of large constructions on bedrock usually is controlled by shear strength of concrete - bedrock cement face 建于岩基之上的大型构筑物，其抗滑稳定性受到混凝土基础与基岩胶结面抗剪强度的控制。
The combined effects of soft rock sites and anelastic attenuation factor have been separated and determined respectively by using this method 采用该方法，分离软基岩场地联合效应和非弹性衰减的影响，并把二者分别确定出来。
Additionally , features of fourier amplitude spectrum and variation of duration of ground motions with depth in treasure island were discussed 最后，讨论了土层基岩场地上台阵地震动的傅立叶幅值谱和地震动持时沿深度变化的特点。
