近年来 ,全球经济的发展呈现出一种全新的态势 ,传统的农业经济、工业经济正被一种崭新的经济形态———知识经济所取代。当今世界已进入经济全球化、一体化的时代 ,各国只有融入世界经济、参与国际竞争、发挥自己的相对优势 ,才能在竞争中得以充实和发展。加入ＷＴＯ ,不仅给我国经济发展和国民生活带来前所未有的新变化 ,也势必对我国的图书馆事业发展提出新要求。如何顺应形势 ,抓住机遇 ,改革和拓展图书馆工作 ,主动适应市场经济发展要求 ,已成为一项极具战略意义的现实课题。1　“入世”给图书馆带来的挑战1 1　国内市场经济的冲击。长…     

"入世"后金融犯罪的发展趋势及对策思考

中国“入世”是适应经济全球化、国际化、一体化趋势的不可逆转的重要步骤。中国“入世”将推动科技进步,生产发展,流通扩大和跨国集团的兴起,从而缩短时空距离,淡化国界区别,使人、财、物进入大流动时代,但同时也对人们的思想观念以及我国初步建立的社会主义市场经济体系产生巨大的冲击和挑战。目前最敏感、最需要引起我们高度警惕的是经济安全问题。我国作为发展中国家,新旧体制转轨尚未完成,各种法律制度尚未完善,客观上为各类经济犯罪分子提供了可乘之机。金融是经济的核心和杠杆,属于高风险行业,在社会经济运行中起着“放大器”的作用,几乎所有国家的经济安全问题首先都是从金融危机中爆发出来的。“入世”后我国的金融安全问题已成为业

"入世"对万州主要行业的影响及对策

中国加入世界贸易组织(WT0)必将给国内各地区的发展带来不同的机遇和挑战.作为三峡库区腹心地带的万州区在"入世"的推动下将面临加快外向型经济发展的机遇.万州区的外经贸、工业、农业和第三产业的各行各业应该根据"入世"带来的影响和自身实际抓紧研究对策,采取主动积极的措施与国际市场接轨,迎接挑战,争取新的发展.     

关注"三农"问题 实现农村经济可持续发展

我国是一个发展中的农业大国,国家的富强,都依赖于农村、农业、农民问题的突破.农业、农村和农民问题的核心是农民问题,解决"三农"问题关键就是要不断增加农民收入,缩小城乡、地区之间的收入差距.农村产业和就业结构调整是增加农民收入,解决"三农"问题,实现农业和农村经济现代化的根本出路.农村经济的可持续发展有利于促进农村富余劳动力的转移、缩小城乡差距、促进农村社会事业繁荣进步.农业和农村的可持续发展,直接影响着全国人民生活质量的改善和提高,也关系到国民经济发展全局和中国社会主义现代化建设的进程.因此,农村经济在国家经济发展战略中具有很重要的地位,是中国可持续发展的根本保证.该文就农村经济目前存在的问题进行剖析,对促进农村经济可持续发展提出了自己的意见.

聚焦平台—桃花盛开的地方

以标准化生产统帅农业全局加入世贸组织,对我国农业发展带来了强烈的冲击,其核心内容就是“市场的接轨和标准的入世”:国内市场与国际市场融合为一体,根据市场准入原则,我们生产农产品必须坚持国际通用的质量标准体系,也就是说,我们生产的农产品必须达到国际市场的质量要求, 这是惟一的“产品通行证”。从长远看,入世有利于农业资源的合理配置,从整体上提高中国农业的国际竞争力。农业实行标准化生产,是农产品突破出口技术壁垒与国际市场接轨的惟一选择。     

新的绿色革命与环境质量安全

以推广作物矮化品种为核心的“第一次绿色革命”被称为高投入的石油农业,它在给人类带来巨大利益的同时,也伴随着一些负面效应。世界人口的进一步增加和耕地、水资源不断减少所导致的未来巨大的食物供需矛盾,正引发以基因工程为核心的“第二次绿色革命”。由于发展与生态环境恶化的矛盾,我国必须采取有效措施,以同时保证“粮食供给”和“农业环境”双安全。     

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

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.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

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 Index mechanism for multi-scale view in spatial databases

There are numerous geometric objects stored in the spatial databases. An importance function in a spatial database is that users can browse the geometric objects as a map efficiently. Thus the spatial database should display the geometric objects users concern about swiftly onto the display window. This process includes two operations:retrieve data from database and then draw them onto screen. Accordingly, to improve the efficiency, we should try to reduce time of both retrieving object and displaying them. The former can be achieved with the aid of spatial index such as R-tree, the latter require to simplify the objects. Simplification means that objects are shown with sufficient but not with unnecessary detail which depend on the scale of browse. So the major problem is how to retrieve data at different detail level efficiently. This paper introduces the implementation of a multi-scale index in the spatial database SISP (Spatial Information Shared Platform) which is generalized from R-tree. The difference between the generalization and the R-tree lies on two facets: One is that every node and geometric object in the generalization is assigned with a importance value which denote the importance of them, and every vertex in the objects are assigned with a importance value,too. The importance value can be use to decide which data should be retrieve from disk in a query. The other difference is that geometric objects in the generalization are divided into one or more sub-blocks, and vertexes are total ordered by their importance value. With the help of the generalized R-tree, one can easily retrieve data at different detail levels.Some experiments are performed on real-life data to evaluate the performance of solutions that separately use normal spatial index and multi-scale spatial index. The results show that the solution using multi-scale index in SISP is satisfying.
