1. 研究目的与意义（文献综述） 1.1 The aim of this research This research aims to evaluate two sets of textbooks that has used in WHUT for non-English learners, and determine if these textbooks fit both the students’ and teachers’ needs, and if there are some improvement to make in the future. 1.2 Literature review Textbook evaluation refers to the evaluation of teaching materials (textbooks, handouts, etc.). The content of a textbook should fit the outline, and keep a proper amount with a strong ideological、scientific and systematic features. In a word, textbook evaluation has a variety of specific methods. During this research, the evaluation model of McDonough and Shaw (2003) suggests that there are two stages on evaluation: external evaluation and internal evaluation. External evaluation is mainly through the cover of the textbook and the catalogue and other external elements. From the external evaluation, it can roughly contains an understanding of the applicable

1. 研究目的与意义（文献综述） This paper is aimed to reveal the current situation and problem existing in teaching writing in English, and think about some strategies in improving teaching English writing from the perspective in Core Competence as mentioned in the title. This paper mainly focuses on several aspects related to teaching English writing according to the standard of the Core Competence and values for Chinese students development: Firstly, it would offer introduction about the Core Competence and values, including the background, the process of development, main branches, aspects under each subcategory, as well as four aspects of Core Competence in English; The Core Competence was first proposed in China by Ministry of Education in 2014. Since the concept of Core Competence was put forward, the definition and connotation, the ways of training, the methods of evaluating have been under researches. Among the subcategories of Core Competence, English Core Competen

1. 研究目的与意义随着社会经济的发展,技术创新已成为企业发展的核心,更是推动现代经济增长的关键因素。改革开放30年以来,中国的经济发展取得了举世瞩目的成绩,但回首过去的发展历程不难发现,我们的高速增长是用高投入、高消耗、低产出的粗放型发展方式换来的。作为一个资源有限、人口众多的发展中国家,我们不能再一味追求这种成本极高的发展方式,对此,政府提出了建设创新型国家的发展战略,通过增强自主创新能力、加快产业升级步伐,最终实现经济增长方式的转变。在这样的经济背景下,研究金融发展对技术进步的促进作用及效率,对于深化中国金融发展模式的思考,加快金融体制改革,改善企业的融资环境,更好地为技术创新和经济发展服务,具有重要的现实意义。 2. 研究内容和预期目标技术创新已经成为经济增长的核心动力，是一国经济持

1. 研究目的与意义（文献综述） 装配式预应力混凝土连续箱梁在目前桥梁工程当中应用非常广泛，它是通过在工厂内先预制好各个节段，而后再吊装至桥位处拼接并张拉预应力，使得结构由简支转为连续体系的一种施工方法。这种方法能够充分利用各梁段的截面，使得材料消耗降低；预制过程和下部结构可以同步进行，从而缩短了工期；在施工过程中避免使用大量支架，减少了空间使用率及施工费用。而小箱梁本身具有较好的抗扭刚度，在活载作用下变形小，耐久性强，在同等跨径的结构中具有一定经济优势。由于该施工过程中，结构发生了体系转换，因而需要对其内力进行分析验算，以有利于对各施工阶段作出管理控制。 从国内外对该类桥梁的研究现状看，主要有设计和施工两方面的内容：设计方面，目前普遍采用有限元法作为结构分析的�

1. 研究目的与意义（文献综述） 目的：黄铁矿作为一种典型金属硫化物尾矿,在自然环境中容易被Fe3 、O2以及氧化亚铁硫杆菌等氧化,从而产生高酸、高重金属含量的酸性矿山废水(AMD)，以及发生自燃的现象，自燃后的黄铁矿体就会失去大量的有效硫，不能再用。因此分析和掌握粒度、升温速率和质量这三种因素对黄铁矿氧化自燃影响的规律。从而从宏观的角度判定黄铁矿石的自燃倾向性，有利于开采过程中在矿床的开拓、采矿方法选择、通风系统设计的同时，采取积极、有效、经济实用的防火措施，实现安全与生产效益的最优化。 意义：在黄铁矿的开采中，黄铁矿常温下在空气中极易发生自燃，产生大量的热和二氧化硫，使空气中的二氧化硫浓度升高，二氧化硫是一种无色的中等刺激性气体，主要刺激呼吸道，吸入后对作业人员的呼吸系统功能收

1. 研究目的与意义（文献综述） The purpose of the thesis: The society of materials and fierce job competition has witnessed the issue of the spoken English of English major student a heated debate among general public. There are higher requirement for job seekers or the graduates who go in for the re-examination. Therefore, speaking English fluently is crucial for the every English major students and if they can take advantages of the spoken English, they will have greater competitiveness. However, there is a problem among the students, that is the majority of students can’t meet the requirements of the enterprise or the college. The main reason i analyse is the different teaching measure has different effects, so the teaching measure is taking an important part for teaching of speaking. Oral English teaching is not satisfactory and many teachers face a problrm of considering how to develop learners' oral English proficiency. Thus, to find ways of systematically and prac

1. 研究目的与意义（文献综述包含参考文献）Literature Review Waiting, as Ha Jin#8217;s second novel, describes a story about waiting that lasts for 18 years among three persons: Lin Kong, Shuyu Liu and Manna Wu. At the beginning of the novel, Ha jin told the 17th time that Lin Kong attempted to divorce Shuyu, but still failed. As an officer of the army hospital in Muji, Lin Kong had a twelve-day leave every summer when he could return to Goose Village to see his wife and daughter. However, he would put forward the divorce since 1968 because he fell in love with another woman in the hospital, Manna Wu who was a nurse. Every time his wife Shuyu would go back on her word at the courthouse for she still loved Lin Kong. Time and time again, Lin Kong and Manna became desperate, only to wait the 18th year. There was a regulation in the hospital saying that if an officer had been separated with his wife for 18 years, ha could ask for a divorce whether his wife was
