1983—1985年进行的“清理攻关”,是我国地震预报研究过程中的一项重要部署。当时的任务要求是:对十多年来地震预报的观测技术、观测资料和预报方法从科学上进行全面的清理。它不是一般的工作总结,而是通过广泛深入地科学研究,作出科学鉴别的评价,所以叫做清理攻关。现在提出的科学攻关,则是在认清现有科学技术现状的基础上,分析地震预报研究发展的动态,提出新的科学目标,跨出新的步子,既要研究利用已有 相似文献

1引言1999年11月29日,在辽宁省岫岩-海城交界处发生了5．6级地震,震前做出了准确的预报,也采取了有效的预防措施,因而取得了显著的经济效益、社会效益和很好的政治影响,受到了中国地震局和辽宁省人民政府的表彰,也受到了广大地震工作者的关注．可以说,这次地震预报成功是我国东部经济发达、人口稠密地区继1975年海城7．3级地震预报成功后,二十多年中又一次成功的地震预报事件．这既让广大地震工作者为地震预报多年含辛茹苦地探索,终于又一次取得进展而欢欣鼓舞,同时也都在思考,为什么辽宁的地震工作者这么幸运,1975年海城地震预… 相似文献

This review covers several aspects of magnetopause research during the two-year period from mid-1991 to mid-1993. It focusses upon three topics which received renewed attention: the structure of the steady-state magnetopause, the origin of the transient events which are superimposed upon it, and the cause of transient signatures observed by high-latitude dayside ground magnetometers. Case and statistical studies defined the relatively unknown characteristics of the magnetosheath plasma layers lying outside the magnetopause, while theoretical studies provided alternative explanations for the presence of magnetosheath plasma within the LLBL. Evidence was presented for a steady transition from magnetosheath to magnetospheric plasma parameters. Detailed studies described the plasma, energetic particle, and magnetic field characteristics of transient events in the outer dayside magnetosphere, and multipoint studies provided important new information concerning the ionospheric response to sudden changes in solar wind parameters. This review emphasizes the competing explanations which have been advanced to explain these phenomena. 相似文献

The article presents the results of a hydrogeological survey aimed to substantiate the engineering recultivation of accumulation ponds of lignin mud by inwashing it with coal ash. The ash bed causes compression consolidation of lignin bed, leading to an increase in the pond seal margin. The mass exchange between the ash and the lignin mud is accompanied by changes in the hydrogeochemical conditions: the mineralization of the liquid phase of technogenic soils increases by a factor of up to 8, and the concentration of microcomplex increases to very high values. The analysis of the qualitative state of groundwater showed it to be tolerant to the effect of accumulation ponds. The moderate deviation from the local natural background is due to other pollution sources. The applied recultivation technology is effective and environmentally safe, though it needs modernization. The alternative technology, proposed by OOO VEB-Inzhiniiring, i.e., grouting the pond content, is extremely hazardous, and the implementation of the project involves considerable environmental risk because of the possible loss of pond containment. 相似文献

Almost no new theoretical work has been conducted in the area of mid-latitude F-region plasma instabilities since Perkin's (J. Geophys. Res. 78 (1973) 218) linear theory. New experimental data now suggest that the nonlinear development of mid-latitude F-region structures includes large polarization electric fields which dominate the final state. Airglow and radar data show that ΣP is greatly depleted in some regions, which is in agreement with a polarization hypothesis. We hope these new results will inspire new simulations with some anticipation of solving this perplexing but fascinating problem. 相似文献

Summary from earth-current observations made at Mogadiscio the lunar-diurnal variation has been derived for the northward component, and by means of a special method lunar variations during daylight hours and night hours have been determined separately. The results have been compared with corresponding results from other observatories.
Zusammenfassung Für die Nordkomponente des Erdstromes in Mogadiscio ist die mondentägige Variation abgeleitet worden, und ferner sind die lunaren Variationen dieser Komponente, für die Stunden des Tages und des Nachts getrennt, durch eine spezielle Methode hergeleitet worden. Die Resultate sind mit entsprechenden Resultaten anderer Observatorien verglichen worden.相似文献

The magnetopause separates the geomagnetic field from the interplanetary plasma and performs finite motions under the action
of the solar wind pressure variable in time. Accelerations originating in this case result in that the necessary condition
for the development of the Rayleigh-Taylor instability is formed at quite a definite motion phase. We can anticipate that
the instability will develop during compression of the magnetosphere. It should be taken into account that the magnetopause
is a potential tangential discontinuity. On the one hand, a plasma flow along the magnetopause results in a decrease in the
Rayleigh-Taylor instability threshold. On the other hand, the Kelvin-Helmholtz instability threshold, typical of the tangential
discontinuity, also decreases during the magnetosphere compression phase. Thus, if we speak about the magnetopause, it is
natural and necessary to jointly consider both types of instability. Main information on the combined Rayleigh-Taylor-Kelvin-Helmholtz
instability is presented, the dispersion equation determining the evolution of small perturbations is considered, and the
possible geophysical applications to the theory (e.g., penetration of the solar plasma into the magnetosphere, excitation
of global Pc5 oscillations) are indicated. 相似文献
