公婆泉盆地局部排泄源氧化还原属性与铀矿化关系探讨

在系统分析公婆泉盆地地质背景、水文地质条件的基础上，对该区局部排泄源氧化还原属性与铀矿化的关系进行了探讨。研究结果表明，局部排泄源的存在对铀矿化具有重要作用，当局部排泄源属于还原性质时，铀矿体常常分布于该排泄源上游；若属氧化性质，排泄源铀矿体通常位于其下游或附近。公婆泉盆地存在相对氧化和相对还原的二种局部排泄源，北骆驼泉区的沙泉沟与平沙地、麻黄沟、北骆驼泉沟排泄源之间应为有利的铀矿化地段。     

我国各地膨润土的热性质

对各地膨润土的热性质进行了考察，讨论了膨润土差热曲线和热失重的形态特征，以及膨润土热性质与其他物理化学性质的关系。研究表明，供试膨润土均可观察到三组吸热效应，部分样品可观察到一组放热效应。其中第一组吸热谷因层间所含有阳离子的种类和数量不同而呈现单谷或复谷两种不同的形态；根据第三吸热谷与放热峰这两个效应的峰间隔差和形态变化对供试膨润土进行属型划分简单易行。     

原始数据图数据自动标注方法

原始数据图是化探工作中重要的基础性图件，其数字化制图是一项费时费力的工作。利用Microsoft Visual Fox Pro、MAPGIS软件实现分析数据的自动标注，可大大地简化原始数据图制图，提高工作效率。     

Flood Damage Reduction Program (FDRP) in Québec: Case Study of the Chaudiére River

This study presents the evolution of agreements between the governments of Canadaand Québec on flood damage reduction. In Québec, the implementation of a regulation about building in floodplains came about in 1983–1984. Today, this regulation takes the form of a policy called ``Policy of shores, littoral and floodplain protection'. Municipalities must adopt rules that concur with the principles of this policy.The Chaudiére River basin was selected for analysis of urban developmentduring the period following the application of building rules in flood-risk areas.Despite the ban on building in the strong current zone (0–20 year return periodflood zone), many buildings, essentially residential, have been erected in thiszone. These new constructions generally account for a low percentage of thetotal property value in the 0–100 year flooding area, but are legal since theyare connected to a water and sewage network that existed prior to the officialfloodplain regulation.Flood damage along the Chaudiére River will tend to increase for two reasons.Firstly, while respecting the policy mentioned above, sites are still available infloodplains for future development. Secondly, no structural flood protection workshave been erected in view of the fact they are only marginally profitable from anbenefit-cost point of view.

The transition from people''s property to private property: Consequences of the restitution principle for urban development and urban renewal in East Berlin''s inner-city residential areas

The constitutional decision to return to their original owners all real-estate property in East Germany that had either been expropriated or placed under state administration (the restitution principle) has had significant consequences for urban development and urban renewal. Experiences from East Berlin's innercity residential areas illustrate the effects on the state of repair of housing, the character of residential neighbourhoods, the tenants living in the areas affected, and the future structure of real-estate ownership. The case studies reveal a picture of a contradictory development of residential neighbourhoods, including shifting power relations and new polarizations, especially between tenants and landlords.
