This paper deals with the newest data to do some researches on the earthquake prediction by MT repeated measurements. The data are from the first MT monitoring profile about 400km long in north margin of Qinghai-Tibet Plateau. Five earthquakes of M 5 to M 7 occurred during monitoring along the profile. After studying several MT parameters of the time and space domains on the basis of the error analysis, we found the perfected parameter of the MT monitoring and the perfected frequency range of the MT monitoring....

This paper deals with the newest data to do some researches on the earthquake prediction by MT repeated measurements. The data are from the first MT monitoring profile about 400km long in north margin of Qinghai-Tibet Plateau. Five earthquakes of M 5 to M 7 occurred during monitoring along the profile. After studying several MT parameters of the time and space domains on the basis of the error analysis, we found the perfected parameter of the MT monitoring and the perfected frequency range of the MT monitoring. During the activity of great earthquakes accompanied by strong earthquakes and at the depth equal to that of most continental earthquakes (between 10km and 20km from surface), the apparent resistivity of the measurement coordinate axis, apparent resistivity of the main axis, apparent resistivity of the real part and apparent resistivity of the imaginary part all show that the electroconductibility of the media changes in form of drop-rise-recovery,and the skewness and azimuth of the main axis show that the cross heterogeneity of electricity is abated apparently. At the same time, the synchronous and same-phase variations of the MT parameters in wide range might correspond to the regional precursors of great tectonic earthquakes. The lead and lag variations of the MT parameters between local regions, the relative variation amplitude declines as the distance from the focus increases, might correspond to the regional precursors of the strong earthquake which is caused by the movement of the structures. This forms a chain-like relationship in which large background of seismicity is superposed on it small background. The cause about the case has been studied in detail.Monitoring of perfected MT profile can provide rich and reliable criteria for development processes of continental earthquakes and mid- and short-term earthquake prediction.

本文研究了青藏高原北缘第一个长约400km的MT监测剖面上所获得的5次5-7级地震前后的资料。着重分析了在相当于大陆多震层深度范围内壳内介质的多种MT参数(视电阻率、相位、主轴方位角、扭曲度等).这些MT参数在大范围内的同步-同相变化和局部区域之间的超前、滞后变化、相对变化幅度随震中距增大而衰减的特征,可能分别对应着构造孕育型大震的地区性场兆和构造运动型强震的区域性场兆,形成了地震活动大背景叠加小背景的一种链式关系。运用"MT监测优显参数"进行择优监测,将可能为大陆地震的震源物理发展过程和中短期预报提供丰富可靠的判据。

A simplified method is suggested for determining the modes of the soillayer with varible properties- Therefore an effective computing approach isdeveloped for analyzing the seismic responses of different types of soil layers. Thismethod is based on the one-dimensional shear wave equation and the modalperturbation technique. The modal characteristics of the complicated soil layer arecalculated approximately in a subspace spanned by several lower modes of anequivalent homogeneous soil layer with the same depth,...

A simplified method is suggested for determining the modes of the soillayer with varible properties- Therefore an effective computing approach isdeveloped for analyzing the seismic responses of different types of soil layers. Thismethod is based on the one-dimensional shear wave equation and the modalperturbation technique. The modal characteristics of the complicated soil layer arecalculated approximately in a subspace spanned by several lower modes of anequivalent homogeneous soil layer with the same depth, average shear modulusand mass density. As a result, solving the wavo equation with variable coefficientsis replaced by solving the linear algehraic equations. The simplified method can beapplied easily to the layored homogeneous soil, and also to the soil layer in whichthe property of soil media changes with depth in any form, such as analytical ordiscrete form. The numercial results show that precision of the method is betterthan the othor methods suggosted before.

What on earth is the media—newspapers or the press, televisions or TV stations? The traditional concept of media hasnt defined it clearly, and the current changes which show as the development of information technology generating amalgamation and fission of the media, the endless emergence of new media, and thus mergers in media industry confused it much more. To grasp the very essence and laws of media changes is of great practical significance and also an important subject for the communication theory. This article just deals with the following questions: what is the media, what is the essence of media changes, where does the basic power of media changes come from, how will the media changes affect the existing three big media, and can the traditional commuication theory be applied to the reality of media changes any more.

报纸是媒介还是报社是媒介 ?电视是媒介还是电视台是媒介 ?到底什么是媒介 ?传统的媒介概念 ,对这些问题没有清楚的界定 ,而当前媒介的不断变革又使媒介的概念更加难以把握。透过纷繁的现象去认识媒介变革的本质与规律 ,在今天特别具有重大的现实意义。这也是信息传播时代向传播学界提出的世界课题。媒介是什么 ?媒介变革的本质是什么 ?媒介变革的根本动力来自哪里 ?媒介变革将对现有的三大媒介产生怎样的冲击 ?传统的传播学是否还能适应媒介变革的现实 ?本文就是对这些问题的探索和思考。
