前震是地震前兆观测中的一个重要物理量,前震的研究对地震预测的发展尤为重要,前震序列的典型特征包括加速发生的小震与古登堡-里克特定律（Gutenberg-Richter Law）中的b值变小.本文在Dieterich提出的地震发生率模型的基础上,探讨前震发生的力学成因机制及前震-主震-余震时域演化特征.模型分析结果表明,前震震源区断层及其断层周边剪应力加载速率的变化可能是前震发生及地震发生率变化的一个关键原因.由于前震震源区次级断层之间剪应力加载速率受来自主震成核过程中断层自加速滑移的影响升高,从而可导致这些次级断裂的加速失稳,即加速前震的发生.当震源区内由前震所产生的静态应力扰动不可忽略时,应力扰动和主震成核的共同作用也可对后续前震发生率产生影响.当正向应力扰动出现时,后续的前震序列的地震发生率会出现陡增,随后其地震发生率逐渐下降.而当负向应力扰动出现时,地震发生率会出现陡降,然后再次逐渐上升.基于Kostrov模型,本文得到了剪应力加载速率与古登堡-里克特定律中b值的关系式,结果表明前震序列中b值的减小与前震区内的剪应力加载速率的上升有关.  相似文献

Concentration of Peroxides and Formaldehyde in Air and Rain and Gas-Rain Partitioning     

O. Largiuni  M. C. Giacomelli  G. Piccardi 《Journal of Atmospheric Chemistry》2002,41(1):1-20

Rain and air of Florence have been collected in a continuous way andanalysed by flow analysis spectrofluorimetric methods for formaldehydeand hydrogen peroxide. Diurnal and seasonal variations were observed;the mean/maximum concentrations of all data (as gm^–3) are 3.3/23.4 for HCHO and 0.4/4.93 forH₂O₂. The effect of external sources and ofphotochemical reactions produces periods of positive and negativecorrelations for these compounds. The mean/maximum rain concentration ofall data are 98/443 g l^–1 for HCHO and 84/685 g l^–1 for H₂O₂. Concentrationratios rain/air and discrepancies to Henry's Law equilibrium arediscussed.  相似文献

用宽频带辐射能量检验地震能量标度性   总被引：1，自引：0，他引：1       下载免费PDF全文

吴忠良  高原 《地球物理学报》1995,38(2):206-212

本文研究了宽频带辐射能量的能量－频度关系，并试图以此对地震能量标度性假说进行重新检验．结果表明，宽频带辐射能量与其他震级标度之间似乎并不存在一个理想的能量－震级关系，然而至少对所研究的日本和阿拉斯加地区而言，直接针对宽频带辐射能量的频度统计可以得到更好的标度性．  相似文献

Anisotropy of magnetic susceptibility of rocks in the Rayleigh Law region: Modelling errors arising from linear fit to non-linear data     

F. Hrouda 《Studia Geophysica et Geodaetica》2007,51(3):423-438

The anisotropy of magnetic susceptibility (AMS) within the Rayleigh Law range was investigated theoretically, using mathematical modelling. It was revealed that the orientations of the principal susceptibilities and the shape parameter vary with field so weakly that these variations can be regarded as negligible from the practical point of view. The degree of AMS increases with field according to the degree of anisotropy of the initial susceptibility used and according to the intensity of susceptibility change with field of the mineral considered. The degree of AMS calculated using linear theory is very near to the degree of AMS following from the analysis of AMS within the Rayleigh Law range. If it is desirable to correct the field-dependent degree of AMS, a simple technique is suggested based on measurement of the AMS in two fields. fhrouda@agico.cz  相似文献   

Bio-logging of marine migratory species in the law of the sea     

《Marine Policy》2015

The use of advanced and emerging remote data-collection technologies, and in particular bio-logging of marine migratory species, raises fundamental questions about the scope of authority of coastal states to regulate marine scientific research in the waters under their jurisdiction. Bio-logging involves the attachment of devices to marine animals that collect and transmit data about their movements and aspects of the local marine environment, and is now routinely used by marine scientists to support conservation programs and augment oceanographic data collection. Tagged marine life, including seabirds, marine mammals, sea turtles and pelagic fishes, may interact unpredictably with the territorial seas and exclusive economic zones (EEZs) of numerous coastal states. This article explores the legal implications of bio-logging within the legal regime of marine scientific research in the law of the sea. Although bio-logging is a form of marine scientific research, when it is initiated outside a coastal state׳s jurisdiction it does not later fall within it, even if the tagged animals subsequently enters a coastal state׳s territorial sea or EEZ.  相似文献   

Bio-logging as marine scientific research under the law of the sea: A commentary responding to James Kraska,Guillermo Ortuño Crespo,David W. Johnston,bio-logging of marine migratory species in the law of the sea,Marine Policy 51 (2015) 394–400     

《Marine Policy》2015

Rapid advances in attaching miniaturized electronic devices to marine animals for the purpose of learning more about their behavior and interaction with the marine environment, known as bio-logging, raise important and unsettled questions under the international law of the sea. Part XIII of the United Nations Convention on the Law of the Sea (UNCLOS) provides coastal states with the right to regulate and authorize marine scientific research in offshore areas under their sovereignty and jurisdiction. In their recent article published in this journal, James Kraska, Guillermo Ortuño, and David W. Johnston, assert that although bio-logging is a form of marine scientific research, Part XIII of UNCLOS does not apply to tagged animals that collect scientific information within a coastal state’s 200 mile exclusive economic zone, territorial sea, or internal waters. This commentary rejects Kraska et al.'s interpretation and provides evidence to support the claim that coastal state consent under Part XIII of UNCLOS may, under some circumstances, apply to bio-logging. In light of the immense scientific contributions that bio-logging research provide to global marine conservation efforts and the possible burdens that may be imposed on researchers if coastal states begin to assert their rights under UNCLOS, it is important that the international community engage in a robust and candid discussion of the issue and develop a consensus-based approach on how best to move forward.  相似文献
