在远场正演计算的基础上，运用30°～90°的四个不同深源远震记录波形，通过试错法选取台站下方的结构，借助波场反向重建算法，反演确定宜昌台站下方的速度结构。

The vertical offsets are larger in the Shenxi Gou and the Bajiao Miao sections,reaching locally 5～6m in maxima,and generally lower in the Miaoba section,1～2m or less. Near the Gaoyuan village,the surface rupture consists of two subparallel branches. The northern branch shows mostly rightlateral slip with minor SE sideup thrusting,and the southern one mostly SE sideup thrusting.

其中，深溪沟段和八角庙段同震垂直位错较大，达。5～6m；庙坝段同震垂直位移量普遍较低，1～2m或更低；在高原新村附近，地表破裂带分为近平行的南北两支，北支以右旋走滑为主，南支以南东盘逆冲抬升为主，这与与映秀-北川同震破裂总体北西盘抬升的性质相反。

计算结果表明：(1)所采用的方法与已有的模型实验结果有很好的对应关系，可用于分析建筑物存在下的场地砂土液化问题；(2)饱和砂土透镜体液化对短周期建筑物主要起到隔震作用，且随着透镜体厚度、埋深和宽度的增加以及场地输入地震动加速度的增大，减震效果有所增加；(3)在冲击型地震动作用下，埋深浅、宽度和厚度小的液化透镜体有时却对短周期结构加速度反应起到增大作用。

In this paper,we have discussed the seismotectonic environment that located at the depth and shallow crust and seismology and geology model caused 1927 Gulang earthquake.

Ms Wu is a★ virtuoso[4] interpreter of traditional music, creating hauntingly exotic waves of sound with★ pizzicatos and tremolos[5]( the plucking of one string with all five fingers consecutively).

吴女士使用弹拨和震音（5根手指连续拨动一根弦）奏出了众多令人萦怀的异国曲调，其诠释传统音乐的造诣之深可见一斑。

Institute of Petroleum Exploration and Development,PetroChina,Lanzhou 730020,ChinaEarthquakes occured overmuch and seismites developed in southwestern Qaidam basin. The seismites made serious seismic-related soft-sediment deformation structures,including pillow structure,ball structure,pillow bed,liquefied sand-stone vein,liquefied mudstone vein,micro-fault,micro-fracture,micro corrugated lamination and sandstone fungus.

研究表明，柴达木盆地西南地区地震活动强烈，深、浅层均发现一系列与古地震有关的震积岩，形成一系列软沉积物变形构造，主要包括震积砂枕、砂球构造、枕状层、液化砂泥岩脉、层内错断、地裂缝、微褶皱纹理、沙侵蘑菇等。

Near post 47km there is a high dip angle fault stretching from the lower part of the upper crust to the top of the crust_mantle transitional zone. This strike_slip fault has a direct bearing on the occurrence of the Jiashi strong earthquake swarm and is an inferred causative fault for the swarm (1997) according to this study.

剖面47km桩号附近，上地壳下部至壳幔过渡带以上地壳范围内存在一条高倾角的深断裂，具有走滑性质，本研究认为该深断裂与1997年伽师强震群的发生密切相关，推断它为伽师强震群的发震构造。

Shallow moonquakes are located at depth of about 50-220 km, they are strong but rare, and with high-frequency. Deep moonquakes are located at the depth of about 700-1150 km, and occur as clusters related with the tidal stress between the Earth and the Moon.

月震按震源深度分布分为浅源月震与深源月震，前者的震源深度大约为50~220km，释放的能量较大但发生次数较少，记录信号以高频成分为主；后者的震源深度大约为700~1150 km，并具丛集性，与潮汐应力有关。
