新疆部分城镇远震和近震影响的确定方法

以建筑抗震设计规范ＧＢＪ１１－９（条文说明）中涉及到的新疆地区考虑远震影响的城镇为研究对象，采用现行的地震危险性分析概率方法，考虑远震和近震影响的实质，提出了一处合理的确定远震和近震影响的方法，进而确定这些城镇的基本烈度是远震影响还是近震影响。     

关于甘肃地区小震调制比异常区域面积选取问题的讨论

利用甘肃省地震台网１９８８年以来的地震目录，对计算对小震调制比的区域面积选取作了研究，发现存在一个适用的最小面积，其大小约为６个平方度。     

西藏自治区城镇发展战略初探

西藏自然条件较差，经济基础薄弱，城镇发展落后，但在新的时期，它有着很好的发展机遇和来自多方面的动力；文章详细分析了这些因素对西藏城镇发展的积极影响及今后发展中应坚持的指导思想，提出今后城镇发展中应壮大核心城市拉萨及副中心城市日喀则的综合实力，积极培育区域中心城市，小城镇的发展应以县城和边贸口岸为主，并重视农牧区的合理集聚。     

Early Palaeozoic Evolution of the Zhen'' an- Xichuan Block and the Small Qinling Multi-Island Ocean Basin

Based on studies of palaeogeography, palaeobiogeography, palaeomagnetism, geochemistry and volcanism, this paper proposes that the Zhen'an-Xichuan area was a small Early Palaeozoic block rifted away from South Qinling and suturing onto North Qinling earlier than the other parts of South Qinling. In the Early Palaeozoic Qinling was a small archipelagic ocean basin with 5 rows of islands including the Zhen'an-Xichuan block. The drifting of the Yangtze and North China plates and the islands between them in the same direction at different speeds caused their suturing process to be different from the classic plate collision, which is the major feature of the suturing of the multi-island Tethys ocean basin. This also explains the problem that the Caledonian collision did not result in orogeny in eastern Qinling.

Properties of New Coordinates for the General Three-Body Problem

This is an analysis of the features of the new coordinate system given by the principal axes of inertia, as determined by Euler angles, and twodistances related to the inertia principal moments and an auxiliar angleas coordinates, for studying the general three-body problem, interactingthrough gravitational forces.The reduction of order is performed in these new coordinates by using the angular velocity vector or the Euler angles.The Eulerian case of collinear motion is revisited from our own perspective.The value of the auxiliar angle is computed for the Sun–Earth–Moon system.     

非洲欠发达地区首都新城开发策略研究

近年来,以各国首都为代表的非洲城市呈现高速扩张态势,由此催生了新城开发的浪潮。本文梳理了非洲新城开发的理论和实践,总结了其背景和驱动力、关键性角色及面临的挑战。以刚果共和国首都布拉柴维尔市东部新城开发实践为例,通过实地调研获取资料,总结其驱动因素,概述了所在国政府、企业、金融机构等的作用,以及其存在的政治经济形式不稳定、土地交易市场不成熟、地质灾害风险等现实挑战。以新城概念规划方案为蓝本,提出设计弹性城市规划方案、建立完善土地管理制度、政企协同开发、多渠道筹备资金、工程设计保障地质安全、建设通达的道路交通系统、各类需求或文化背景人群分片开发住宅区、建造经济便捷的住宅产品、配建符合各方需求的公共服务设施、设立与当地经济发展相适应的产业园区开发策略。     

Cross-Checking: A Method to Test the Comprehensiveness of Pigot’s Nineteenth-Century Plans of Manchester & Salford

The long sequence of Pigot’s plans of Manchester and Salford is used to test the concept that the dates of churches and chapels can be used as a valuable indicator of the completeness of the coverage of large-scale nineteenth-century town plans. The approach appears to hold some promise and suggests that Pigot’s plans were surprisingly comprehensive. This may reflect not merely his drawing on existing surveys but, more interestingly, may be the incidental product of collecting data for his town directories. The methodology could usefully be extended to explore the value of directory plans of other towns.     

相位萃取技术在InSAR小数据集上的应用

相位萃取技术可最小化多基线InSAR处理中干涉像对的去相关噪声,已成为雷达干涉测量研究领域中热点技术之一。本文首先设计并实现了一套专门针对小数据集的基于相位萃取技术的多基线InSAR处理流程。整个流程分为两大模块。第一个模块为称为预处理模块,通过图像配准、地形相位移除等操作生成相位萃取技术所需的零基线SAR图像堆栈。第二个模块首先基于多视像元生成相干矩阵,并且在此基础上完成相位萃取操作。然后,利用小基线集技术的思想在萃取相位上分离出各相位稳定点上的形变情况。为了保证结果可靠性,在这一模块中还加入了大气相位预估与移除的步骤。最后,该流程被应用到了5景拍摄于太原地区的PALSAR图像上。实验结果表明,相位萃取技术在小数据集情况下仍然能够有效提升数据的相干性,这有利于多基线InSAR输出结果密度的提升。
