西部地区能源供应的可持续研究

我国西部地区资源丰富,战略地位重要,社会经济发展潜力巨大.西部大开发战略实施以来,许多地区都希望通过开发本地区的能源资源,参与国家重大能源工程,加快自身的发展.但是,西部地区能源资源的开发利用仍未在观念和体制上摆脱旧的发展模式的束缚,资源的不合理开采、忽视生态和环境保护的倾向还比较严重.因此,必须走可持续发展的道路,使能源资源的开发利用与环境保护、生态建设相协调,促进和带动当地社会经济发展和人民生活水平提高.     

新疆能源资源生产结构演进分析及展望

各种能源资源生产结构的调整既反映了资源物藏量、资源开发技术、资源使用的政策导向,也反映了经济结构和社会生活方式。新疆是中国能源资源最丰富的地区之一,研究新疆能源结构具有研究经济结构的"信号"意义。借助于能源资源的数据分析研究新疆能源资源生产的结构演进,并结合定性分析方法对新疆能源资源结构演进的发展趋势展望预测。     

论西部中小学英语课程资源及其开发

西部地区中小学英语课程资源具有自身的特点,根据学科性质,具有稀缺性、非本土性、非生活性、纯记忆性、人为性;根据地域特征,在总体上较为缺乏、结构和品种单一、开发程度和水平低、更新换代步伐缓慢、英语教师的水平较低。主要存在开发意识淡薄、制约因素较多、结构不尽合理、缺乏地方特色等问题。要有效开发西部英语课程资源,就应充分发挥教材和教师的作用、努力实现英语课程活动的生活化。     

山东省生物质能源发展战略研究

发展生物质能源对改善能源结构、保护生态环境、发展农村经济有重要作用。山东省生物质资源丰富,技术条件和产业基础较好。山东省在户用沼气、生物质直燃发电、纤维素乙醇等领域的生物质能源利用上全国领先;但在产业发展中存在原料收集困难,产业布局不合理,综合效益低下等问题。促进生物质能源产业的可持续发展,应该在政府主导和政策扶持的基础上建立产业发展的市场运行机制,加强资源调查和产业规划,注重国际合作和科技创新,因地制宜,多元发展。黄河三角洲和海洋生物质能源的开发是山东省生物质能源发展的中长期战略重点。     

第15届应用物理知识竞赛几道能源问题的解析

能源问题，是21世纪人类社会发展所面临的主要问题之一，我国实施的西部大开发战略，是一个既能推动西部经济文化发展，又能在很大程度上解决东部能源资源相对短缺的双赢战略，就开发和利用能源方面来说，西气东输工程和西电东送工程，目前已基本完成，现就第15届初中应用物理知识竞赛几道有关能源问题的试题解析如下。     

林木生物质能源消费市场性分析

发展替代能源,改善能源结构,不仅是低碳经济的需要,也是保证未来能源供应之必需。本文以吉林西部木质煤示范项目为例,以木质煤敏感性分析为起点,从不同角度阐述了能源消费市场条件下的林木生物质资源市场性问题。笔者认为现阶段木质煤产业发展所处的市场和政策环境是完全有利于其产业发展的,但是在现阶段的能源区域市场能力上,政策因素对能源消费市场的引导作用十分重要,应结合市场因素发挥作用。     

生物能源开发和使用的进展

西部民族地区水电开发的必要性探析——以甘肃省甘南州为例

加快水电资源的开发利用是缓解能源压力、解决能源供求矛盾、改善能源消费结构、保护生态环境、促进社会经济可持续发展的必然选择和现实途径.我国先后确立一系列加快水电资源开发利用的战略和规划,特别是西电东送、西部大开发战略的实施,给水电资源富集的西部民族地区带来了千载难逢的发展机遇,水电资源开发利用势必将发展成为西部民族地区最具优势的支柱产业,极大地拉动民族区域经济发展.     

“能源资源的开发——以我国山西省为例”教材剖析（人教版）

本节教材以能源开发的重要省份——山西省为典型案例,从自然环境的整体性和差异性角度,以能源资源开发条件（区域的背景条件）、能源基地建设、能源的综合利用（最优战略）和环境的保护与治理（区域可持续发展）阐述能源资源合理开发与区域可持续发展的关系。教材开篇介绍“能源资源”这一核心概念,紧紧抓住“非可再生资源”的有限性、开发过程与生态环境质量的密切相关性以及煤炭在我国能源乃至世界能源结构中的重要地位,呈现出山西省能源基地建设中所面临的机遇和难题。紧接着以“四个框题”的形式,有序展开教材内容。     

评析西部地区的经济发展条件

西部地区的优势和劣势是什么 ?只有十分清楚地了解其发展条件 ,才能扬长避短 ,因地制宜 ,更有效地开发西部。文章分析了西部地区的优势 :矿产资源、能源资源、可开发利用土地资源、生物资源、旅游资源等自然资源丰富 ,对外开放条件相对有利 ;而劣势突出 :生态环境脆弱 ,高素质劳动力和建设资金等经济资源匮乏、基础设施薄弱。

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

Western and Eastern culture differences in commercial field

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity.

团图为数的图中的闭团贯数

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
