西部民族地区经济发展的现状与思考

西部民族地区整体经济发展水平不仅滞后于全国平均水平,而且大大低于东部地区。恶劣的生态环境,保守的思想观念,落后的农业经济,素质较低的人口构成了西部民族地区经济发展的障碍。为促进西部民族地区经济发展,合理的对策思路有:生态环境建设与保护;转变思想观念,鼓励创新思维;发展现代农牧业,实行多样化经营;发挥地缘、人缘优势,发展边境贸易;发挥旅游资源优势,大力开发旅游产业;重视人力资本投资,鼓励科技制度创新。     

西部民族地区科技发展创新的战略模式与选择

科技发展创新能力是现代经济发展的强大的驱动器。目前,我国科技创新能力与世界发达国家之间有很大的差距,西部民族地区科技能力更是薄弱,加快西部民族地区经济产业结构调整,促进经济又好又快地发展,必须把科技创新纳入经济发展的整个过程。首要的问题就是如何选择适合于我国民族地区的科技创新战略模式。根据我国西部民族地区发展的实际,民族地区当前的科技创新模式主要是依靠技术引进与推广和一定程度的技术综合能力,因此是＂引进＋模仿＋综合＂的模式。

湖南东、西部地区经济差距的人口因素探讨

湖南东、西部地区在产业结构、国民经济发展水平、基础设施建设和科教文化发展状况等四个方面存在着经济发展差距；而人口因素的差距及其对经济发展影响是湖南东、西部地区经济差距的重要原因；全面提高人口综合素质是发展湖南西部地区经济的可行性对策。     

西部大开发的制约因素及应对策略

实施西部大开发受一系列因素制约：人口因素、科技开发能力、经济规模、经济结构、交通运输、开发资金、生态环境等。必须相应地制定应对策略，例如：实施人才资源发展战略，加速科技体制改革，调整和优化产业结构，加强交通、水利等基础设施建设，吸引外部资金，走可持续发展之路。     

后发优势与渝东北地区经济发展分析

后发优势的实质是后发国家或后发地区在实现工业化和现代化过程中,具有在技术、制度、发展经验等方面向发达国家或发达地区学习的广阔空间和强烈的学习动力.渝东北地区地处三峡库区腹地,目前仍然是西部相对落后的地区,其经济发展水平与发达地区相比还存在着巨大差距,但也表明渝东北地区拥有巨大的后发优势.在分析现实经济基础(人均GDP低、城镇职工工资水平低、农民收入水平低、产业结构不合理、交通基础设施薄弱)之上,提出了使渝东北地区潜在的后发优势转变为现实的经济优势,实现经济跨越式发展的战略建议:各区县政府应提升调控能力,统筹区域经济发展;敦促企业学习,提高自主创新能力;构建区域合理产业分工体系;加强基础设施建设, 改善落后地区经济发展条件.     

关于我国西部地区建设资金来源的分析

我国西部地区由于自然、历史、社会等原因,经济发展相对落后,全国尚未解决温饱的贫困人口大多分布于该地区。西部地区的基础设施水平与东部地区相比差距很大,成为制约经济发展的"瓶颈"。为了促进西部地区的发展、缩小东西部的差别,1999年召开的中央经济工作会议提出了西部大开发战略。西部大开发战略以投资启动,着眼于推进西部地区的基础设施投资。因此,本文对西部地区建设资金的来源、西部地区财政实力对建设的保障情况进行了概要的分析,希望能为西部开发起一点作用。     

关于实施西部大开发战略的思考

西部地区是一个特殊的人地关系地域系统,正确认识西部地区人地关系中存在的突出矛盾是十分必要的,加快基础设施建设和生态环境建设,大力发展科技教育,积极调整产业结构,是因地制宜实施西部大开发战略的重要举措。

区域经济与生态环境发展协调度研究——以遵义市为样本

中国西部民族地区地貌独特,生态系统脆弱,经济发展与生态环境间的矛盾尤为突出。以遵义市为例,通过构建经济水平评价体系和协调发展度模型对该市2001~2010年的区域经济与生态环境发展的协调程度和协调水平进行评估,发现虽然十年来该市经济指数不断上升,生态环境质量较好,但其经济水平整体却并不高。虽然西部民族地区区域经济与生态环境协调度不断改善,但要实现两者的优质同步发展目标,仍需进行产业结构调整、创新经济和环境协调发展模式。     

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.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

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.     

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.

橡胶颗粒沥青混合料低温抗裂性试验研究

以AC-13级配为基础,将橡胶颗粒代替部分集料掺入混合料中,以低温弯曲试验为评价方法对不同橡胶颗粒掺量下沥青混合料的低温抗裂性进行研究,并引入应变能密度值对混合料的低温抗裂性进行综合评价.试验结果表明:橡胶颗粒沥青混合料试件的破坏微应变均超过2 300,满足冬寒区的技术指标;无论是否掺加橡胶颗粒,随着温度的下降,沥青混合料破坏时的最大弯拉强度增大,弯拉应变降低,劲度模量增大;弯曲应变能密度在胶粒掺量为1%左右时具有较大的弯曲应变能密度值,此时橡胶颗粒沥青混合料具有较好的低温抗裂性.     

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。     

Quantitative trait loci （QTLs） for quality traits related to protein and starch in wheat

Quality traits in wheat （Triticum aestirum L.） were studied by quantitative trait locus （QTL） analysis in a recombinant inbred line （RIL） population, a set of 131 lines derived from Chuan 35050 × Shannong 483 cross （ChSh）. Grains from RILs were assayed for 21 quality traits related to protein and starch. A total of 35 putative QTLs for 19 traits with a single QTL explaining 7.99-40.52% of phenotypic variations were detected on 10 chromosomes, 1D, 2A, 2D, 3B, 3D, 5A, 6A, 6B, 6D, and 7B. The additive effects of 30 QTLs were positive, contributed by Chuan 35050, the remaining 5 QTLs were negative with the additive effect contributed by Shannong 483. For protein traits, 15 QTLs were obtained and most of them were located on chromosomes 1 D, 3B and 6D, while 20 QTLs for starch traits were detected and most of them were located on chromosomes 3D, 6B and 7B. Only 7 QTLs for protein and starch traits were co-located in three regions on chromosomes 1D, 2A and 2D. These protein and starch trait QTLs showed a distinct distribution pattern in certain regions and chromosomes. Twenty-two QTLs were clustered in 6 regions of 5 chromosomes. Two QTL clusters for protein traits were located on chromosomes 1D and 3B, respectively, three clusters for starch traits on chromosomes 3D, 6B and 7B, and one cluster including protein and starch traits on chromosome 1D.     

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.
