十三陵地震台观测技术系统优化改造

在北京十三陵地震台建设了一个高度集成的地震观测监控系统,将原来分散的观测项目(如测震、GPS、气氡、气汞、电磁波、地电场等测项),改造为集中到一台服务器管理,在一个监控平台上统一实现了对台站数据的收集、入库、管理、处理、监控等业务;对这些观测项目可以在控制台上直接取数并将数据入库;初步实现了观测数据的收集、数据处理、数据管理、数据监控的软件管理系统,减少了系统维护工作量,方便台站工作人员操控。监控系统的地震前兆数据监管软件系统DataMonitor可准实时监视数据,检查数据的异常和到达情况,并向台站数据管理人员告警;可对数据库数据进行统计,包括数据到达情况统计、缺数统计、数据连续率统计等。该系统还提供多种前兆数据处理方法,实现对前兆数据的各种常规分析处理。     

论灾害管理与经济发展的辩证关系

本文以ＡＢＣ分类法说明了减轻地震灾害的重要意义，指出了地震灾害绝对损失数额一般会随社会经济发展而逐渐增大这一客观事实。文中提出了表达地震灾害危险性、防抗灾工程投资和社会经济发展关系的一般数学模型，对灾害管理与经济发展的辩证关系进行了讨论。     

1995年世界重要地震灾情及地震活动特征

1995年全世界发生197次6级以上地震，其中有30次7级以上的地震（最大震级8．1级）。具有灾害性的地震为33次，伤亡20人以上的，国内及边界地区为4次，国外有15次，其中有2次灾难性的大地震。该年地震与1994年相比呈明显增强趋势，为本世纪以来第三个强震最多之年。1995年世界地震灾害的主要特点为地震袭击现代化大城市，造成惨重的人员伤亡，惊人的财产损失数额。

Recycling-oriented characterization of plastic frames and printed circuit boards from mobile phones by electronic and chemical imaging

This study characterizes the composition of plastic frames and printed circuit boards from end-of-life mobile phones. This knowledge may help define an optimal processing strategy for using these items as potential raw materials. Correct handling of such a waste is essential for its further “sustainable” recovery, especially to maximize the extraction of base, rare and precious metals, minimizing the environmental impact of the entire process chain. A combination of electronic and chemical imaging techniques was thus examined, applied and critically evaluated in order to optimize the processing, through the identification and the topological assessment of the materials of interest and their quantitative distribution. To reach this goal, end-of-life mobile phone derived wastes have been systematically characterized adopting both “traditional” (e.g. scanning electronic microscopy combined with microanalysis and Raman spectroscopy) and innovative (e.g. hyperspectral imaging in short wave infrared field) techniques, with reference to frames and printed circuit boards. Results showed as the combination of both the approaches (i.e. traditional and classical) could dramatically improve recycling strategies set up, as well as final products recovery.     

Research on the evolvement of morphology of coking coal during the coking process

The evolvement of morphology and structure of the coal with different metamorphic degrees during coking process in the vertical furnace was investigated by infrared Image detector. Moreover, the temperature distribution in the radial direction and the crack formation were also studied in heating process. The results show that the amount of crack and the shrinkage level of char decrease with the coal rank rising. In addition, the initial temperature of crack formation for char increases with the coal rank rising.     

Spatial distribution of soil radon as a tool to recognize active faulting on an active volcano: the example of Mt. Etna (Italy)

This study concerns measurements of radon and thoron emissions from soil carried out in 2004 on the eastern flank of Mt. Etna, in a zone characterized by the presence of numerous seismogenic and aseismic faults. The statistical treatment of the geochemical data allowed recognizing anomaly thresholds for both parameters and producing distribution maps that highlighted a significant spatial correlation between soil gas anomalies and tectonic lineaments. The seismic activity occurring in and around the study area during 2004 was analyzed, producing maps of hypocentral depth and released seismic energy. Both radon and thoron anomalies were located in areas affected by relatively deep (5-10 km depth) seismic activity, while less evident correlation was found between soil gas anomalies and the released seismic energy. This study confirms that mapping the distribution of radon and thoron in soil gas can reveal hidden faults buried by recent soil cover or faults that are not clearly visible at the surface. The correlation between soil gas data and earthquakes depth and intensity can give some hints on the source of gas and/or on fault dynamics.
