三维隔震(振)支座的工程应用与现场测试

首先介绍了一种新型三维隔震(振)支座,该支座由联接件、竖向隔振支座和水平隔震支座组成。竖向隔振支座和水平隔震支座具有较小刚度,采用该类型支座的隔震结构,其竖向基频和水平基频可远离地铁、铁路振动和地震的主频,从而实现竖向隔振和水平隔震作用。其次介绍了该三维隔震(振)支座在某一地铁平台上部结构中的应用情况,对该类型支座进行了竖向性能和水平性能试验。最后对三维隔震(振)结构与传统结构进行了地铁运行时结构振动的对比测试。测试结果表明:三维隔震(振)系统对振动的高频信号具有显著衰减效果。     

远东地区f0Es剧增与K指数突变的关系

一、前言 中纬度地区电离层E_s的成因与影响因素是一复杂的问题。远东地区E_s既多又强,其它电离层现象也有一些特色,本文在文献[9]的基础上,从分析原始频高图入手,对远东地区夜间f₀E_s剧增与地磁K指数的关系作了统计研究,发现两者之间关系甚为密切,即地磁K指数的突然变化伴随着夜间E_s层临界频率f₀E_s的剧烈增加。     

塔里木盆地北部中、新生代钻孔岩芯古地磁研究──喜山期岩石重磁化与油气移聚

对来自塔里木盆地北部５口钻井的部分中、新生代沉积岩岩芯样品进行了古地磁研究，通过对重磁化组分和特征剩磁组分与露头样品的比较，确定了井下样品的喜山期严重重磁化；并通过烃类分析和对磁性分选颗粒的扫描电镜观察，发现了与碳氢化合物有关的球形磁铁矿颗粒和具有黄铁矿格架颗粒的球形磁铁矿聚集体，从而认为重磁化与油气移聚相关，据此确认了喜山期的油气移聚．     

Indian Ocean tsunamis: environmental and socio-economic impacts in Langkawi, Malaysia

We report the results of a study of the physical characteristics and socio-economic impacts of the Indian Ocean Tsunami of 26 December 2004 on the tourist island of Langkawi, Malaysia. In comparison with many other locations struck by the tsunami, the immediate physical and socio-economic impacts in Langkawi were relatively minor. A detailed survey of the watermark and ground elevations was undertaken in the worst affected area between Sungei Kuala Teriang and Sungei Kuala Melaka. Here, the tsunami reached a maximum elevation of 4.29 m as it crossed the coast, with a maximum flow depth of 2.0 m and a very consistent run-up elevation relative to mean sea level of 300 ± 10 cm. The tsunami inundated inshore areas for 300 m and penetrated inland along creeks for 500–1000 m. Structural damage to buildings was confined to within 50–150 m of the shoreline where about 10% of the houses were completely destroyed and 60–70% suffered significant structural damage. Damage was particularly severe in areas where there was no engineered coastal protection, but while coastal revetments did provide enhanced protection for houses at the waterfront, the coastline in the study area appeared to be more heavily impacted than elsewhere in Langkawi because wave energy was focused on the area by offshore breakwaters built to protect the Langkawi port and airport. Emergency response after the tsunami was rapid and efficient but would have been improved if the local police station had not been rendered inoperative by the first wave, and if a mechanism had been in place to ensure that informal advance warnings transmitted between Phuket (Thailand), Langkawi and Penang (Malaysia) by tourist operators could have been more widely disseminated.     

Discovery of Radiolarian Fossils from the Aiketik Group at the Western End of the South Tianshan Mountains of Chinaand Its Implications

The Aiketik Group, distributed at the western end of the South Tianshan Mountains, China, is an important lithostratigraphic unit involved in the South Tianshan orogen. It is separated from the adjacent rocks by faults. Generally, the geologists ascribed it to the Upper Carboniferous according to Pseudostaffella sp., Profusulinella sp. and Fusulinella sp. found from the limestone and sandy limestone of Aiketik. Our radiolarian fossils were obtained from the chert samples collected from the Haladaok section located at the upper Tuoshihan River. The fossils mainly include Albaillella undulata Deflandre, Albaillella paradoxa Deflandre, Albaillella sp. aff. A. paradoxa Deflandre, Albaillella sp. cf. A. deflandrei Gourmelon, Albaillella sp., Albaillella excelsa Ishiga, Kito and Imoto (?), Belowea variabilis (Ormiston et Lane), Callella cf. C. parvispinosa Won, Entactinia cf. E. tortispina Ormiston et Lane, Entactinia aff. E. tortispina Ormiston et Lane, Entactinia variospina Won, Entactinia sp., Eostylodicty

DGPS在资源环境遥感中的应用方法研究

为了能够利用较低配置的GPS设备，方便有效地完成与资源环境遥感有关的地物定位测量任务，利用伪距DGPS设备进行了如下试验研究：基站参考坐标对定位精度的影响，基于大地测量三角控制点和WGS84到北京54坐标系转换模型进行基站参考坐标差分测量导算的方法和精度，在导算出的控制点处建立基站进行试验区样地定位测量的方法及所能达到的精度，试验结果表明，在具备测区至少一个三角控制点和坐标转换参数条件下，可以采用首先从已恬三角点导算出一个位于方便位置处的点的大地坐标，然后在该点所能达到的在当地坐标系中的相对定位精度远远小于一个像元大小，可以推广应用到资源环境遥感的各个应用领域，在不具备基站参考坐标和坐标系转换参数的条件下，可以基于差分测量结果之图形要素绝对位置图形转换到已经和当地坐标系配准的遥感影上去，采用这种办法，在差分处理时不用考虑基站的精确WGS84地心参考坐标，也不用考虑坐标系的转换参数，利用其站单点绝对定位结果作为参考坐标进行差分就可，可以节省不少人力和物力，试验研究及结论为如何利用较低配置的伪距DGPS设备，简捷，快速，精确地完成资源环境遥感领域地物定位测量任务提供了有益参考。
