西南某电站右岸倾坡内夹泥裂隙成因探讨

西南某拟建大型水电站的右岸岩体中存在倾向坡内的夹泥裂隙，通过对其的发育情况以及所处的地质环境进行系统的研究和认真剖析，认为该区内的倾坡内夹泥裂隙的成因并非正常卸荷引起，而是在构造的基础上，穹隆挽近期隆起的结果，为右岸坝肩稳定性评价提供了可靠的依据。     

区域经济空间集中化的产业成因分析——兼析海南省经济空间集中化问题

经济空间集中化起因于产业经济活动在一定空间内聚集并形成大规模的专业化生产，它以区域城市为增长中心，与区域产业结构转变有着密切的关系。经济空间集中化过程大致可以划分为三个与区域产业结构转变有关的经济增长阶段：初级阶段——均衡低速增长；中级阶段——集中快速增长；高级阶段——稳定增长。     

Transport and Housing Security in the Klang Valley, Malaysia

This paper explores links between transport and housing security issues for the urban poor using the example of the Klang Valley in Malaysia. The interface between these issues is identified as a gap in the literature, including policy debates, on both housing and transport. A number of linkages are shown to be important and likely to be relevant in many cities of the South, especially those with rapid motorisation and large numbers of "squatters". A simple framework for understanding these linkages is presented. Key examples include displacement to make way for transport infrastructure and the impact on transport problems for the poor of policies affecting the location of urban poor housing, including relocation sites and transit accommodation. The case study of the Klang Valley is used to illustrate and test the relevance of a focus on this issue and the utility of the conceptual framework. Some policy implications of the investigation and case study are suggested.     

Structure cristalline d'une ménéghinite naturelle pauvre en cuivre,Cu0,58Pb12,72(Sb7,04Bi0,24)S24Crystal structure of a Cu-poor natural meneghinite,Cu0.58Pb12.72(Sb7.04Bi0.24)S24

Cu-poor meneghinite from La Lauzière Massif (Savoy, France) has the composition (electron microprobe) (in wt%): Pb 59.50, Sb 20.33, Bi 1.19, Cu 0.87, Ag 0.05, Fe 0.03, S 17.62, Se 0.05, Total 99.64. Its crystal structure (X-ray on a single crystal) was solved with R1=0.0506, wR2=0.1026, with an orthorhombic symmetry, space group Pnma, and a=24.080(5) Å, b=4.1276(8) Å, c=11.369(2) Å, V=1130.0(4) Å³, Z=4. Relatively to the model of Euler and Hellner (1960), this structure shows a significantly lower site occupancy factor for the tetrahedral Cu site (0.146 against 0.25). Among the five other metallic sites, Bi appears in the one with predominant Sb. Developed structural formula: Cu_0.15Pb₂(Pb_0.53Sb_0.47)(Pb_0.46Sb_0.54)(Sb_0.75Pb_0.19Bi_0.06)S₆; the reduced one: Cu_0.58Pb_12.72(Sb_7.04Bi_0.24)S₂₄. The formation of such a Cu-poor variety seems to be related to specific paragenetic conditions (absence of coexisting galena), or to crystallochemical constraints (minor Bi). To cite this article: Y.

基于树结构的数字遥感图像存储方法与应用

数字遥感图像一般是采用栅格结构来存储。图像中地物的结构特征是隐含其中的。该文从图像识别角度，重点研究了基于树结构的数字遥感图像存储方法。这种方法与遥感中常用的四又树等存储方法不同，它注重图像中地物本身的结构特征。通过树结构使像元按地物目标形成一个个的组合体。该文以机场跑道识别为例，介绍了基于树结构的数字遥感图像存储方法的应用以及将图像变为树的算法。     

西方城市空间结构研究的理论进展

文章综述了西方国家城市空间结构研究的理论进展，概括了城市空间结构各时期研究的主要内容和理论观点，展望了城市空间结构未来研究的趋势和方向。工业化以前西方城市空间结构研究主要侧重于城市表面形态的揭示，把城市空间结构同发展过程分离开来论述其特性。工业化以后的城市空间结构研究进展十分迅速，在研究中十分重视引入新思想、新理论、新技术和新方法。在不同时期出现了不同的学术派别，并总结出诸多城市空间结构的理论模型。

从洛杉矶地区地震实验计划说起

简要介绍了美国洛杉矶地震实验计划(LARSE)的研究目的、科学思路以及一些重要的研究成果。受LARSE计划实践的启发，文章对我国即将开展的城市活断层探测研究思路提出了几点科学认识：①进行深浅活动构造相结合的探测，建立直到震源深度的活动断裂立体图像；②实施折射／反射相结合的综合性探测，发展高分辨折射技术，弥补数百米-数千米深度范围成像的不足；③重要的活动断层常常具有一定的规模，在空间上构成复杂的构造格局，因此，活断层探测不能局限在城市，而应在一定的空间范围中进行。     

Study of crustal structure with S—wave data from Maqen—Jingbian profile

2-D crustal velocity structure and vp/vs are obtained by processing and interpretation of S-wave data from Maqen-Jingbian deep seismic sounding(DSS)profile.The result shows that there exist obvious differences in 2-D S-wave velocity structure and vp/vs ratio structure along the profile.The S-wave velocities are low and vp/vs ration is high for the westem section of the profile and Haiyuan region,while they are normal for the middle and eastern sections.The changes in lithologic characters of two major anomalous zones are discussed according to lateral variation of S-wave velocity structure and vp/vs ratio structure.It is concluded that the development and occurrence of the Haiyuan strong earthquake is not only related to tectonic activities,but also to lithologic characters of the region.
