近代乡村工业形态的三元模式探析--以近代羊楼洞茶区制茶工业为例

羊楼洞是近代湘鄂赣交界十余州县著名的茶叶集散地和加工中心。“羊楼洞茶区”制茶工业呈现出茶农家庭手工业、资本主义工场手工业和近代机器工业三种生产形态相互依赖、同时并存的格局,并且三者还表现出渐进性、粘连性、实用性等乡村工业形态演进的规律。在传统手工业行业或乡村地区工业形态的演进过程中,渐进性似乎比突发性更明显,嫁接型比移植型更具有生存力。这些特点反映了近代中国乡村工业化的复杂性和艰巨性。     

万州产业聚集带动城市发展的经验研究

作为长江中上游的中等城市,重庆市万州区近年来一直加快城市化建设,以经济技术开发区（下简称经开区）为代表的产业聚集对万州的城市化发展起到了明显的带动作用。同时,万州的经济发展也反作用于万州产业的聚集。文章分析了万州经开区产业聚集和万州城市化的互动发展,希望为中国内陆地区的中小城市的城市化找到一条科学捷径。

万州在西部大开发中的战略定位研究

万州必须客观分析自身在区域中的比较优势,并根据这些优势来确定万州在西部扮演的角色．我们认为,万州的优势不在于其拥有的矿产资源,而在于区位优势、政策优势等．根据万州的比较优势,万州应定位于建立商贸中心和内陆国际自由贸易区．     

关于在万州设立保税区的构想

保税区是一种比经济特区更开放的对外开放形式 ,一般被发展中国家用来促进不发达地区的经济发展。万州是典型的不发达地区 ,建立万州保税区对推动万州及其周边地区经济发展具有重要作用 ,由于万州的特殊条件和国家在西部开发中将加快西部的对外开放程度 ,设立万州保税区的时机已经成熟     

马克思法哲学思想的演进历程

马克思的法哲学本质上是法的形而上学批判。马克思法哲学思想是在对近代自然法学派和德国哲理法学派继承与超越的基础上形成的,其间经历了从理性主义法哲学思想到历史唯物主义法哲学思想的演进历程。它的产生及其演变是一个辩证发展的过程,是马克思不断地颠覆和瓦解法的形而上学基础的过程。

近现代科学观的演进及其启示

16世纪末经启蒙运动而产生的近代科学以机械论和还原论为特征 ,其实质是外在联系观在科学上的表现。 2 0世纪以相对论和量子力学为开端的现代科学 ,历经混沌运动和生物学革命 ,更加强调事物的内在联系。基于科学史的考察为近现代科学观的演进提供了佐证。科学观的演进丰富了科学内涵 ,也推动了科学不断向前发展     

论杜甫作于万州的两首诗

杜甫的《放船》(收帆下急水)作于万州南浦县城。因为杜甫的好友严挺之曾任万州员外参军,他路过万州时必然要看一下老朋友曾经作过官的地方。杜甫的另一个好友李布当时正在万州别驾任上,他也必然要泊船拜访。再从《放船》诗的内容看,一、二句写从忠州至万州西山前的行船情景,三至六句写船过西山时看到的奇特景致,七、八句写泊船后的所见所感。杜甫因李布结识了万州鲜于刺史,《送鲜于万州迁巴州》诗很可能是作于万州。     

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.
