In this paper,we use the data of JiaShi earthquake sequence which was recorded by KAS station and WUS station of the regional digital station network in XinJiang near source region. We have calculated moment tensor solutions of more than 100 Ms≥3.5 earthquakes from 2001 to 2004 by the body waveform inverse. At the same time,we compared our result with Harvard CMT result.

The cause of earthquakes was stated correctly in 1760 by British engineer John Michell, one of the first fathers of seismology, in a memoir where he wrote that earthquakes and the waves of energy that they make are caused by "shifting masses of rock miles below the surface".

事业的地震说明是正确的1760年由英国工程师约翰。 michell ，第一个父亲的地震，在一本回忆录，他写道，地震和海浪的能量，使他们所造成的"转移群众的岩石英里以下表面上"。

From the distribution of microseism, we have not found faults with the activities related to the earthquake clustering phenomenon. In about 3 years during the investigation, the earthquake we measured did not affect the groundwater movements.

从微地震部分亦未发现与断层活动相关之地震丛集现象，而在调查期间所量测到之地震并未影响场区地下水位之升降。

Second, by analyzing the strain of northsouth blocks of the fault, we find an asymmetric displacement distribution between the two sides of the rupture, and the two blocks are subject to compressional and tensional stress respectively. It is a pattern that cannot be explained with the linear elastic theory. However, laboratory experiments and in situ measurements in boreholes have shown that many crustal rocks exhibit a nonlinear elastic behavior in compression and tension with a dependence of the Young's modulus on the minimum principal stress. So we suggest that the nonlinear displacement distribution should be considered when dislocation and hypocentral parameters are analyzed.

进而通过对地震南北盘同震应变的分析，发现了昆仑山地震的南北两盘分别受挤压和拉张两种应力作用，研究表明多种岩石在拉张和压力作用下其最小主应力下的杨氏模量表现出非线性弹性特征，从而提出对昆仑山地震地表位移及震源特征参数分析时应考虑非线弹性介质导致的非线性弹性位移分布特征。

利用2004～2005年Hi-CLIMB计划架设在藏南日喀则附近由28台宽频带数字地震仪组成的二维台阵的地震记录，应用双差层析定位方法对454个区域地震进行了精确重定位，共确定了340个地震的精确位置。

According to the three-components teleseismic records from portable digital seismic station deployed in Himalaya mountain chain region, the S-wave velocity structure beneath 46 teleseismic stations are investigated by using transform function method and SA technique. As reliable geophysics evidence, these results help us to understand the geodynamic process of Himalaya mountain region of Tibet.

The Taichung Domain was moving northwestwards before the 1999 Chi-Chi earthquake: in the footwall of Chelungpu Fault the slip rate was ~10 mm/yr, while in the hanging wall the rate increased eastwards up to 10-30 mm/yr. Two years prior to the earthquake, in the footwall of Changhua Fault the deformation direction changed from WNW to almost due N, and velocity gradient changed from increasing northwards to increasing eastwards, suggesting possible precursor of a large earthquake.

中部地区在集集地震前大致向西北方向位移，车笼埔断层下盘位移速率约在10 mm/yr左右，断层上盘往东侧逐渐增大，在10~30 mm/yr之间；集集地震发生前2年，彰化断层下盘的位移方向由西北西转为偏北的位移型态，位移速度则由南向北增大，转为由西向东增大的趋势；即位移方向与位移速度有明显的改变，可能为地震前兆的相关资讯。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
