The status quo of high-resolution data acquisition system is discussed and by studying the character of high-resolution seismic exploration and seismic signal, the theoretical models and character of each unit are gained. This paper point out that under 1000 meter's depth where petroleum is embedded the IDR of central controlled seismic instrument and telemetricseismic instrument are lower than 70dB which can't meet the needs of high-resolution seismic exploration.

文章论述了当代高分辨率地震数据采集系统的现状，对高分辨率地震勘探及地震信号特点进行了研究，得出了高分辨率地震勘探数据采集系统的理论模型和各功能单元的理论特性，指出在石油与天然气埋藏的千米以下的地层，集中式数字地震仪和24位遥测地震仪的瞬时动态范围均不超过70dB，远远满足不了高分辨率地震勘探的需要。

There, they find that the anomalous groups are variety,similarity and periodicity of development before and after Baotou Ms 6. 4 earthquake, this is similar to Haicheng and Tangshan earthquakes, however, the obviously difference is that the abnormal is no causality and associated relation but paragenic relation with Baotou earthquake. They think the circum --B...

该区异常群体具有种类的多样性、配套性，在包头6.4级地震前后有发展阶段性，虽与海城、唐山地震前确有相似之处，但也有明显不同，认为环渤海地区参与了1996年以包头地震为代表的华北整体性构造活动，该区异常与包头地震无因果或伴生关系，而是共生关系，该区目前仍存在发生5～6级或6级以上地震的危险性。

The seismological informationwork plays an important role in earthquake prediction exploration and research, and in earthquakeengineering application.

地震科技信息的积累和应用是我国地震科学事业发展的基础，我国的地震信息工作在地震预报的探索和研究中以及地震工程应用中，均发挥了重要的作用。

Moreover, the seismotectonic belts were applied in seismic risk region analysis to discuss the relationship among SB, SRR and precursory anomaly.

在此基础上，具体地把地震构造带的概念应用于地震危险区分析之中，探讨了地震危险区及地震前兆异常与地震构造带的关系。

Accurate relocation of the Wenchuan earthquake sequence is obtained by using the double difference relocation algorithm from the integrated travel time data recorded at the Western Sichuan movable seismic array and the earthquake emergency response stations. In this presentation, the seismotectonic deformation and rupture process is also investigated.

综合利用川西流动地震台阵观测数据和震后应急地震观测台站的震相数据，采用双差地震定位方法对汶川地震的余震序列进行了精确重新定位，并对汶川地震的地震构造进行了深入研究。

Using data recorded by telemetric seismic network of Beijing area we discussed the differences of natural earthquake,man-mad earthquake and mine earthquake and analyzed multiple earthquakes and the characters of earthquakes occurred in different areas.

以北京地区台网数据为例，讨论了天然地震、人工地震和矿山地震的区别，并对多重地震和不同地区的地震特征进行了分析。

The long axis of the low intensity isoseism of this earthquake is NW-trending, indicating the effect of the NW-trending west Wuyuan Fault.

包头西6.4级地震高烈度区等震线长轴呈NE向，与乌拉山北缘断裂接近，该断裂是包头西6.4级地震的发震构造。2次地震高烈度区长轴与低烈度区长轴走向相差近90 ，这是因为除发震构造外，烈度区还受一组与之交会的共轭断裂活动的影响。1989年大同-阳高6.1级地震，发生在从六棱山腹地向大同-阳高盆地延伸的NNE向大王村-西要泉断裂上，该断裂是大同-阳高地震的发震构造。

Combining an evaluation of seismic risk in Panjin area is given by determining seismic activity parameter for the design of the considered area , settingup its fortifying-level divided areas and establishing divisions for predicting the destructive degrees of an earthquake when sandy soil is liquidized .

本文利用研究区地质构造特征，古地震和地壳形变等资料建立断层模型，求解地震活动参数，判定未来地震发生的地点、强度和频度，并结合面源模型的地震危险性分析，建立研究区设计地震动参数及其设防水准分区，砂土液化震害程度预测区划，对盘锦地区的地震危险性问题做出了评价。

We modeled the triplicated P waveform to determine the focal depth relative to the 670 km discontinuity and found that the earthquake actually occurred above the discontinuity. Thus even the deepest earthquakes in current catalogs still occur in the upper mantle.

因为地球中的横向不均匀性，地震的绝对深度有较大的误差，所以我们根据观测地震图中明显的三重值特征，对上述那次深地震进行波形模拟，把相对深度和绝对深度结合起来，最终确定地震实际发生在670公里间断面以上，因此我们认为目前目录中那些最深的地震仍然发生在上地幔中。

Our result shows that the best double couple solution of this Mw5.2 event is 315°,64°and 19°for strike,dip and slip angles respectively,the second nodal plane solution is 214°,74°, and 152°.The focal depth is 25±2km,suggesting that this quake occurred in the lower crust which is much deeper than most continental earthquakes.This lower crust earthquake requires that the rock should be colder than expected.We proposed generation mechanism of this deep earthquake and its implications in rock strength and thermal state.

我们以此速度结构作为模型，利用中国国家地震台网5个台站的宽频带地震数据，采用CAP方法反演2003年8月16日赤峰地震震源机制解并初步确定震源深度：再利用IRIS 9个台站远震体波数据，通过对比高频(0.7～2.0Hz)理论地震图和观测记录的方法进一步精确确定震源深度并验证反演得到的机制解，得出此次地震矩震级为5.2，震源机制解为：节面I：315°/64°/19°，节面Ⅱ：216°/74°/152°，震源深度为25±2km，已深达下地壳。
