重点研究了单层球面网壳的非线性动力回应行为，对网壳结构在地震作用下的动力失稳状态以及倒塌现象作了理论上的研究，为"结构倒塌"作出了合理的定义，并进而探讨了网壳结构失稳机理。

The results also show that the module of state vector is more sensitive than other parameters stat...

研究结果还表明，相对于态矢量增量的模、态矢量方向的改变等参量，态矢量的模在震前的变化更为敏感，此外，对于相同震级的地震，最佳扫描区域尺度大小不一，并对这些现象进行了一定的解释。

In this case,it is necessary that the precursor fields are formed by every earthquake to superpose mutually.

1995年7月12日～1996年2月3日在云南及邻近地区曾发生过3次强震，形成了多次地震在短时间内接踵发生的现象。

The winter solstice of 2004 is approaching. From 6 beginning of the months are up to now,Viewed from all kinds of abnormal natural phenomena, e.g. earthquake, red tide, hot weather, rainstorm, flood, tornado and typhoon, Express the waving of "Negative Force" obviously appears. I'm deeply worried about that.

2004年冬至之日越来越近，6月初至今，从各种自然现象如地震、赤潮、高温、暴雨、洪涝、龙卷风、台风频发的异常情况，表明"阴性力"的波动已显露无遗，对此我深感忧虑。

It means that coseismic Coulomb stress changes have transient influences on the seismic potential of active faults.

大陆板内地震的准周期丛集复发行为不只是客观存在的一种现象或规律，而是由内在物理机制所决定的。

Based on the analysis of sequence stratigraphy and seismic stratigraphy of carbonate platforms, especially to the ones in Dongsha and Xisha, this dissertation has identified, for the first time, three major and several minor drowning events of the platforms since Tertiary. Drowning events in the four carbonate platforms, especially in Dongsha Platform, coincide with major global eustatic cycles raised by B.

在经过高技术处理的地震剖面上，淹没层序的特征是顶部同相轴呈光滑的双轨连续强反射，特殊处理后表现出高波阻抗、高密度和强瞬时振幅等特征，还表现为高的速度梯度值和高的剩余速度梯度值，甚至在局部区域出现本层层速度比下部地层层速度高的现象。

Currently, in the oil-field exploitation, existing the phenomenon of garbling the lack thickness of stratum with vertical fault-throw in well logging identification of strata while meeting fault in drilling well. In most case, consider the lack thickness of stratum which contrast the imperfection geologic strata thickness to the well and the well as the fault-throw. The method which using very popular in oil-field exist shortages, it very much easily lead people into the areas of misplay. especially when the seismic person and geology confirm the fault-throw, It often appear inconsistent instance.

目前，在油田开发中钻井钻遇断层时，地质人员时常存在将测井分层与相邻井对比时缺失地层厚度与铅直地层断距混淆的现象，很多情况下把井与井对比缺失地层厚度等同于断层断距等，这些现今在油田非常流行的用法存在一些不足之处，容易把人们引入一些认识上的误区，特别是在地震与地质人员进行断层断距的确定时，经常出现矛盾的情况。

The result indicates that this method can improve the resolution of seismic data effectively and interpret some geological phenomena which can't be recognized in conventional seismic section, and provide reliable information for magmatic rock distribution.

结果表明，该方法有效地提高了地震数据的分辨率，能解释常规剖面上不易识别的一些地质现象，为采区岩浆岩的分布提供详实的信息。

This text analyzes the concept of the environment geology, settle the geology data by survey and the history data of junction area of Hydroelectric Power Station. elaborate the basic geology characteristic of dam area especially junction area, analyze the problem of geology environment in junction area concluding protogenic geological environment and protogenic geological environment. analyze the Physical geology phenomenon such as collapse and mudflow...etc. predict the probability evoked by earthquake in junction area.

本文通过对环境地质概念的辨析，对泸定水电站枢纽区踏勘所得的地质资料和历史资料进行了整理分析，阐述了泸定水电站库坝区特别是枢纽区的基本地质特征，着重分析了枢纽区的环境地质问题，包括原生地质环境及次生地质环境，对枢纽区的物理地质现象如滑坡、泥石流等做了简单的论述分析，并简单预测了枢纽区可能诱发地震的概率。

The results in this dissertation explain some electromagnetic perturbations during seism and during rock failure.

这一研究结果能够较好地解释地震和岩石动力破裂过程中的电磁扰动现象。
