震源机制 meaning in English
earthquake source mechanism
flcal mechanism
focal mechanism
mechanism at the source
mechanism of earthquake focus
source mechanism
Examples
- The focal mechanism is mainly left - lateral strike - slip , with a very small normal fault slip component
这次地震的震源机制基本上是左旋走滑，带有微小的正断层滑动分量。 - It is recognized that the concerted characteristics of the earthquake focal mechanism of earthquake sequence for various types are different
认识到，不同类型的地震序列其震源机制的一致性特徵不同。 - Studies on the earthquake sequences and the source mechanisms of the strong earthquakes show that yunnan has more obvious subarea characteristics of earthquake type
摘要对云南地震序列和强震震源机制的分析与研究表明，云南地区具有较明显的地震类型分区特征。 - We have studied synthetically the tectonic stress field in the three gorges and its adjacent area by use of data of crustal deformation , focal mechanism and borehole stress observation
摘要利用地形变测量、震源机制和钻孔应力测量等资料，综合研究了三峡及邻区的构造应力场。 - The pre - seismic and post - seismic stress direction can be statistically determined by a large collection of foreshock and aftershock focal mechanism data while the stress drop can be determined through the source fracture inversion from seismic wave data or crust deformation data
地震前后的应力方向可根据大量前震和余震震源机制统计给出；地震应力降可通过地震波或地壳形变资料的震源破裂反演研究得到。
