正确认识改革的代价是凝聚改革共识的必要条件

为了更好地凝聚改革共识，必须正确认识改革的代价问题。要改革就不可避免地会付出一定的代价，但改革过程中出现的各种问题并非都是改革的产物；改革代价的表现形式是多种多样的，不同形式的代价对改革与发展所起的作用也不同。改革主体能够能动地调控代价。为此，必须树立“底线思维”，牢牢把握改革代价的合理限度；提高改革决策的科学性；坚持主导性和全面性相统一、预测性和补偿性相结合的改革原则。     

新课程改革下小学数学课堂教学中应注意的问题

实施新课程改革的主要阵地是课堂，小学数学教学改革应以新型的教育观念和教学思想为指导，组织好课堂教学，这是提高教学质量的中心环节。然而，在具体实施课改的过程中，有时为了进行课程改革，往往只重视形式的改革，导致课改偏离了正常的轨道。因此，在课程改革实施过程中，我们应更多注意形式下的实质，把握课程改革的精髓，进一步推进课程改革。

论邓小平的改革观——纪念邓小平南巡谈话二十周年

分析提出了邓小平的改革观：改革是中国的第二次革命，改革就是解放和发展生产力；社会主义发展到今天，不改革只能是死路一条；改革是社会主义发展的直接动力和亿万人民自己的事业；我们的改革是社会主义的巩固、发展和完善，改革应坚持“两条”原则和“三个有利于”的判断标准；改革是有风险的，改革必须正确处理好发展和稳定的关系。邓小平的改革观丰富了马克思主义的改革理论。     

加快推进“两课”教学改革浅论

马克思主义理论课和思想品德课的教学经历了十几年的改革实践，取得了很大进展，积累了不少好的经验。但是，无论是教学效果，还是新形势对“两课”的教学要求，改革的任务都很艰巨。加快推进“两课”教学改革，一要正确认识面临的形势，增强改革的紧迫感，抓住改革的良好机遇；二要进一步明确“两课”教学改革目标，使改革继续沿着正确方向发展；三要大胆探索改革思路，以加快推进“两课”教学改革     

解读农村税费改革

目前，我国农村税费改革已初见成效，但仍存在许多难点，如乡村负债过重，运转困难，影响税费改革的顺利推进；改革意见分歧大，改革试点模式少；配套改革复杂性强等。因此，加快农村税费改革，必须双管齐下，将农村税费制度与税费外制度改革结合起来，以宏观改革为根本，深化整个配套改革。

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.

海南岛地体及其毗邻陆缘晚中生代—新生代古地磁研究和构造演化

本文叙述了对海南岛及其毗邻大陆边缘白垩纪到第四纪地层岩石进行古地磁研究的全部工作过程。通过分析岩石中剩余磁矢量的磁偏角及磁倾角的变化,提出海南岛白垩纪以来经历的构造演化模式如下:早期伴随顺时针旋转而向南迁移,后期伴随逆时针转动并向北运移。联系该地区及邻区的地质、地球物理资料,对海南岛上述的构造地体运动提出以下认识:北部湾内早期有一拉张作用,主要是该作用使湾内地壳显著伸长减薄,形成北部湾盆地。从而导致了海南岛的早期构造运动,而海南岛后期的构造运动则主要是受南海海底扩张的影响。海南地体运动规律的阐明对于了解北部湾油气盆地的形成演化有重要的理论和实际意义。

An on-line scaling method for improving scalability of a database cluster

The explosive growth of the Internet and database applications has driven database to be more scalable and available, and able to support on-line scaling without interrupting service. To support more client's queries without downtime and degrading the response time, more nodes have to be scaled up while the database is running. This paper presents the overview of scalable and available database that satisfies the above characteristics. And we propose a novel on-line scaling method. Our method improves the existing on-line scaling method for fast response time and higher throughputs. Our proposed method reduces unnecessary network use, i.e. , we decrease the number of data copy by reusing the backup data. Also, our on-line scaling operation can be processed parallel by selecting adequate nodes as new node. Our performance study shows that our method results in significant reduction in data copy time.     

An improved R-tree based on childnode''s probability

R-Tree is a good structure for spatial searching. But in this indexing structure,either the sequence of nodes in the same level or sequence of traveling these nodes when queries are made is random. Since the possibility that the object appears in different MBR which have the same parents node is different, if we make the subnode who has the most possibility be traveled first, the time cost will be decreased in most of the cases. In some case, the possibility of a point belong to a rectangle will shows direct proportion with the size of the rectangle. But this conclusion is based on an assumption that the objects are symmetrically distributing in the area and this assumption is not always coming into existence. Now we found a more direct parameter to scale the possibility and made a little change on the structure of R-tree, to increase the possibility of founding the satisfying answer in the front sub trees. We names this structure probability based arranged R-tree (PBAR-tree).     

Integrating GIS Web services based on mediating architecture

The geographic information service is enabled by the advancements in general Web service technology and the focused efforts of the OGC in defining XML-based Web GIS service. Based on these models, this paper addresses the issue of services chaining,the process of combining or pipelining results from several interoperable GIS Web Services to create a customized solution. This paper presents a mediated chaining architecture in which a specific service takes responsibility for performing the process that describes a service chain. We designed the Spatial Information Process Language (SIPL) for dynamic modeling and describing the service chain, also a prototype of the Spatial Information Process Execution Engine (SIPEE) is implemented for executing processes written in SIPL. Discussion of measures to improve the functionality and performance of such system will be included.     

Tracking data management using topology of moving object database system for moving object constrained trajectory in LBS application

Advances in wireless technologies and positioning technologies and spread of wireless devices, an interest in LBS (Location Based Service) is arising. To provide location based service, tracking data should have been stored in moving object database management system (called MODBMS) with proper policies and managed efficiently. So the methods which acquire the location information at regular time intervals then, store and manage have been studied. In this paper, we suggest tracking data management techniques using topology that is corresponding to the moving path of moving object. In our techniques, we update the MODBMS when moving object arrived at a street intersection or a curved road which is represented as the node in topology and predict the location at past and future with attribute of topology and linear function. In this technique, location data that are corresponding to the node in topology are stored, thus reduce the number of update and amount of data. Also in case predicting the location,because topology are used as well as existing location information, accuracy for prediction is increased than applying linear function or spline function.
